Typically, a cabinet with an optional air filter is needed: • in places where dust is a concern • next to a dusty road with heavy traffic • in sandy terrain with the possibility of wind-blown sand in the air • next to an industrial plant with significant emissions of dust or other particles, such as cement factory, sawmill, and so on • nearby a cornfield with heavy straw dust during harvesting • in places where salt fog or acid rain caused by air pollution is a concern • in site locations where surrounding metal structures show signs of corrosion because of the extreme conditions (salt in air) • in locations with especially heavy rainfall and high humidity combined with air pollution • near sea shore: – with dense salt fog because of the breaking waves – with dense salt fog and line of sight to the sea (not behind a large building) 18 DN0951839 Issue: 04 Flexi Multiradio Base Station Installation Site Environmental requirements Requirements – where wind-driven salt fog from sea can be identified For a generic model for sea salt distribution, see Figure 2: Sea salt distribution over land masses. Typically, the further away from the sea the BTS is located the less salt is accumulated. However, because of the local environmental variables a general rule for determining the distance cannot be stated. Always check the local environmental conditions before installing a BTS in the proximity of the sea.

Ensuring public safety This equipment generates radio frequency energy, which has a thermal effect when absorbed by the human body. For this reason compliance boundaries specific to this equipment have been established. The thermal effects of radio frequency energy can exceed safety levels when a person is inside the established compliance boundaries. Observe the compliance boundary, and make sure the general public has no access to areas inside the established boundaries. The information shown in the section Warnings and cautions provided is taken from the relevant section of NSN product documentation containing warnings and cautions specific to the equipment. Installing base stations to ensure installer safety Installation engineers need to be aware of the potential risk of the thermal effects of radio frequency energy and how to protect themselves against undue risk. The information shown in the Warnings and cautions provided section is taken from the relevant section of NSN product documentation containing warnings and cautions specific to the equipment. Warnings and cautions provided Reference safety distances When working close to transmitter antennas, the proper safety distances must be observed. The minimum safe distance from an antenna is measured in metres. f The antenna generates electromagnetic fields at radio frequencies. Do not cross the compliance boundary. f This equipment generates electromagnetic fields. If performing installation or maintenance procedures on the antenna systems, make sure that all the transmitters in the area are switched off. 32 DN0951839 Issue: 04 Flexi Multiradio Base Station Installation Site Environmental requirements Requirements When assessing the applicable boundaries, the European standards EN 50383, EN 50384, EN 50385 and Council Recommendation 1999/519/EC for occupational and general public electromagnetic exposure limits - see Annex A - have been applied. The statements shown below are taken from the NSN product documentation containing warning and cautions specific to the equipment. Assessment applying Specific Absorption Rate (SAR) measurements European standards EN 50383, EN 50384 and EN 50385 do not include specifications for whole body SAR measurements. Whole body SAR measurements are not required for transmitters that have maximum output power levels too low to result in exposure levels that can reach the whole body SAR compliance limits under any conditions. Whole body SAR exclusion power levels have been based on the worst case assumptions. For details, see Table 28: Whole body SAR exclusion power levels. Table 28 Whole body SAR exclusion power levels Exposure category Maximum output power (rms) General public Max power [W] = general public whole body SAR limit [W/kg] * 12.5 kg: 4-year- old child body mass = 1 W Occupational Max power [W] = occupational whole body SAR limit [W/kg] * 42 kg: 16-year-old worker body mass = 16.8 W Localized SAR measurements can only be used when: 1. The separation between the phantom and the outer surface of the energy generating element is 40 cm (15.6 in.) or less. 2. The surface area of the energy generating element is less than 60 cm (23.6 in.) by 30 cm (11.8 in.). 3. The frequency is in the range of 800 to 3000 MHz. For the reasons above, SAR measurements are not applicable to Flexi Multiradio Base Station. Assessment of compliance boundary The compliance boundary is defined as the area around the antenna shown in Figure 3: Area around the antenna. The antenna is located at the origo. Distances from the antenna are shown. The top and side views are shown in Figure 4: Antenna side and top view.

If an exposure limit, antenna, and/or configuration is used which does not correspond to the levels given in tables 'Dimensions of compliance boundary in meters for general public (GP)' and 'Dimensions of compliance boundary in meters (Occupational)', the compliance boundary must be re-calculated according to EN50383. • The formula for calculating the compliance boundary using the far-field model, which is referenced in EN50383, is given in ANNEX B later in this section. This model is applicable for calculating the compliance boundary for the far-field region and over estimates the compliance boundary for the radiating near-field region, but is not applicable for calculating the compliance boundary for the reactive near-field region where the distance from the antenna is less than or equal to λ / 4.

Therefore, all calculations are valid when the compliance boundary is greater or equal to the antenna dimensions plus λ /4. The minimum safety distance (compliance boundary) in metres, or 'rmin', is calculated according to the equation in Figure 6: Formula for safety distances: Figure 6 Formula for safety distances DN02152589 The meaning of each formula component is as follows: • N is the number of transmitter units per one antenna Issue: 04 DN0951839 39 Environmental requirements Flexi Multiradio Base Station Installation Site Requirements • G is the antenna gain (in dB) • L is the minimum cable losses (in dB) • Pout is the maximum power of one transmitter unit (in W) • S is the maximum power density limit (in W/m²) Note that in the far-field, the field calculation does not take into account the antenna size, which is assumed to be a point source. Therefore, when calculating the compliance boundary, the far-field data, antenna size and reactive field criteria have to be taken into account. 5.10 Compliance with EMC, RF and safety In Europe, this means compliance with Directive 1999/5/EC of the European Parliament and of the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual recognition of their conformity.

Any special requirements for installation must also be identified during the survey. Steps 1 Check that the BTS can be installed safely: • The site is accessible, adequately lit and safe for working. • Safety distance calculations are made and taken into account. • The site is prepared according to drawings. • The site survey is complete. • The Site Survey Report is available. • The site is clean. • Product delivery is complete. • All wiring is done in accordance with national electric code. • Needed equipment is available as defined in the Site Survey Report. • Sufficient service clearances are available. 2 Verify that the following external cabinet connections are available: • Grounding busbar, • Mains power (AC or DC, depending on the site), • Transmission connection point. 6.2 General site requirements Ensure that the following BTS site requirements are met: 1. All required documentation is available, for example, site-specific installation instructions. 2. When radio link transmission is used, the line-of-sight to the far end radios has been ensured. 3. External connections for the cabinet are available: site grounding point, mains power (AC or DC according to the site), and transmission connection point. Furthermore, AC or DC distribution panel and AC electric are available for power tools. 4. Main grounding (earthing) is installed and tested. 5. Floor or wall surface is even (installation base flatness requirement is 2 mm (0.08 in.). Issue: 04 DN0951839 43 Site requirements Flexi Multiradio Base Station Installation Site Requirements 6. Wall or pole at the BTS site is strong enough to withstand the weight of the BTS. 7. Wall or pole at the BTS site is strong enough to meet earthquake requirement Telcordia GR-63-CORE Zone 4 (only applicable in earthquake areas). 8. Pole at the BTS site is strong enough to withstand the wind load. 9. The BTS is not taken out of its delivery package until the site construction work is finished and the site is clean and dry. 10. Site security is established so the BTS and other units can remain undisturbed at the site. 11. Make sure you can take the BTS to the installation site. For example, in roof top installations, the hole through which you take the BTS to the roof must be large enough. 6.2.1 Indoor site requirements If installing the BTS to an indoor site, ensure that the following indoor BTS site requirements are met: • Door and lock to site room are properly installed and operational (recommended). • Access to the site is secure. • The site is adequately lit. • Feeder entry hole and cable rack for feeder and power cables are ready, if needed. • Heater, or air conditioner, is installed and operational, if needed. This depends on the heat emission and the environment. 6.2.2 Choosing site for the Remote Radio Heads f CAUTION! Risk of personal injury. The unit might have very hot surfaces when operating in hot environments. The unit should be installed in a restricted access location so that unintentional touch of the unit hot surface is blocked. The Remote Radio Head is a heat dissipating unit and so it runs at a temperature notably above the local ambient. If the temperatures of the unit become excessive the unit runs less efficiently, therefore the unit should always be mounted vertically as detailed in these instructions, in an area with unrestricted airflow/ventilation. Solar radiation can also significantly increase the temperature of the unit and so should be taken into consideration when choosing a location for the unit. In particular it is recommended that the finned surfaces should be shaded from the sun. Ideally in the Northern Hemisphere the unit should be located on a North facing wall where it is shaded from the sun; or in a location where an adjacent object or building offers similar shade. In the Southern hemisphere the unit is should ideally be located on a South facing wall. In areas where the temperature can be considered to be moderately warm, or the ambient temperature could reach temperatures of approaching 30°C (86ºF) or above and shade is not given to the unit by any of the adjacent walls or buildings then a solar shield should be fitted to the unit. 44 DN0951839 Issue: 04 Flexi Multiradio Base Station Installation Site Site requirements Requirements 6.3 Feederless site and Distributed site solution requirements 6.3.1 NSN SFPs and cables properties Table 35 3 Gbps SFPs and cables properties Property SFP type (sales code) FOSG (472063A) FOSA (471546A) FOSL (472807A) Link length Up to 200 m over OM3 Up to 15 km Up to 2 km (recommended above 2 up to 200 m over OM2 km) using Standard Multi Mode ITU-T G651.1 or IEC 60793-2-10 (A1a,b/A1a.2) using Standard Single Mode, ITU G.652 or IEC 60793-2 Type B1.1 or IEC 60793-2 Type B1.3 or g Note that only two cables can be used for one link. corresponding fibre Link speed 3.072 Gbit/s Center Wave length 850 nm 1310 nm ± 50 nm 1310 nm ± 50 nm Total allowed attenuation for 3 dB 9.5 dB 3 dB the link Transmitter output power 247 µW 290 µW 150 μW (OMA) Receiver sensitivity (OMA) 61 µW 24 µW 23 µW Extinction ratio (min.)

Power Source (BBU) to Remote RF (not taking into account possible chaining of BBU Power source → FSM/PDU → FRM) – is assumed with guaranteed/maximized BBU time, that is voltage drop in cable is limited to 6,0V. – is calculated with worst case conditions, that is the lowest operational input voltage. g Note: • Cable Short circuit current maybe limiting cable maximum length. This depends on selected distribution Circuit Breaker. Site designer is responsible to calculate end select proper circuit protection case by case. • Installation method affects to the maximum allowed conductor current (Inside insulation, Inside conduit, surface installation, ground installation, etc.). • National variations exist and have to be taken into account by site designer. • Use of optional sales items (like FSES) might have impact to voltage drop calculations. • HW Limit is 25mm². If a thicker cable is needed, then external jumping is needed. • NSN recommended DC feeder cable type is MCCMK or MCMK shielded cable. An equivalent locally supplied DC cable might be used, it is also recommended to use shielded twisted pair cable type.

An equivalent, locally supplied DC cable might be used. Make sure that both ends of the connection to the Flexi RF Module or the System Module are IP65-protected. Shielded power feeder is always needed for installation when the power feeder length exceeds 4 m. The power feeder cable needs to be grounded at both ends. External surge protection is always needed for installation with the System Module DC input (FSMF with or without FPFD) if the input power feeder length exceeds 10 m (installed closely to DC input port). External surge protection is always needed for installation with the System Module DC output if the output power feeder length exceeds 10 m (installed at the System Module end only). Some RFMs require an OVP (FSES/FSEC) close to it if the power feeder length exceeds 10 m. See Table Lightning surge requirements for selected RF Modules. DC cable extension: • There is an additional NSN IP55 2 m DC cable in the FSEC sales package. By cutting both cables in one end and using IP55 protection to both the RF Module and System Module they can be used for extending the DC cable distance. • A long DC cable needs to be shielded and grounded. • Connection of the long DC cable and NSN IP55 cable is recommended to be done in an IP55 outdoor weather protected space, for example in Flexi External OVP box (FSEC). • The FSEC clamping range is from 19 mm to 28 mm DC cable diameters. t If the diameter of the cable is smaller than 19 mm (0.75 in.), use either self- fusing tape or heat-shrinkable tube to increase the cable diameter to 20 mm-21 mm (0.79-0.83 in.) to fulfil the IP67 requirement. The distance between the expansion and the stripped part of the cable must be at least 10 cm (4 in.).

Up to four 3U modules can be fitted on either pole mounting kit, and up to three Remote Radio Heads can be fitted on one FPKA. • Up to four 3U modules can be fitted on VMPB and FPKA/FPKC. • Up to three Remote Radio Heads can be fitted on one FPKA. • Up to two 2x60 W RRHs can be installed with an FMFA on the same FPKA. Only one 2x40 W RRH can be installed with an FMFA on the same FPKA. • A 2x60 W RRH can be installed next to an FMFA on an FPKA. A 2x40 W RRH cannot be installed next to an FMFA on an FPKA. • If there is an FMFA installed on the pole mounting kit, RRH can be installed next to FMFA. • If two FMFAs are installed on a pole mounting kit, RRH can be installed next to FMFA. f Excess torsion damages the casings. In wall and pole installation, do not install more than two modules per plinth. g Modules installed outdoors can be left non-operational for a maximum of one week. The fluctuation of temperature during one day can be 30°C (86°F) at the maximum. When installing modules on a pole, make sure that the pole at the BTS site is strong enough to withstand the weight of the BTS, to meet earthquake requirement Telcordia GR-63 core Zone 4, and the wind load requirement.

Follow these guidelines when selecting antenna jumper cables: • 1/2" or 3/8" antenna jumper cables can be used. 1/2" antenna cable connectors can be connected directly to the module. A right angle connector is required for connection to the RF Module. • The length should be determined based on the Flexi Multiradio BTS installation option (for example pole, wall, cabinet, third-party cabinet) and the distance of the BTS from the antenna feeder line. • Antenna jumper cables must be rated IP65 or better. • Super flexible antenna jumper cables with smaller connector heads make installation easier. 70 DN0951839 Issue: 04 Flexi Multiradio Base Station Installation Site Power requirements Requirements 7 Power requirements 7.1 Site earth and BTS grounding requirements BTS site grounding is divided into two contexts: site earthing and site equipment grounding. To protect the BTS from damaging over voltages through antenna equipment, communication cables, or power supply lines, grounding cabling must be planned and installed before the installation of the base station. To avoid interference, it is recommended that large grounding systems are designed case-specifically. The function of the site earth is to convoy the lethal and hazardous voltages and electric currents from the site main grounding point (main grounding busbar) to the earth. The impedance of the earth connection should be as low as possible: • The earthing (grounding) resistance target of the BTS site is ≤10 Ω. If it is not possible to reach this target because of the difficult conditions, for instance in areas such as solid rocks or dry desert, the earthing (grounding) resistance can be max. 150 Ω. • The cross-sectional area of the Main Earthing Conductor should not be smaller than live (L) and neutral never less than 6 mm2 (10 AWG), recommended size is 16 mm2 (6 AWG). For NEBS installations, 16 mm2 (6 AWG) or higher is required. Site equipment grounding is required to ensure personnel safety and to avoid electrostatic discharge which can damage the equipment. An AC power plug with a protective earth (PE) connection is not sufficient. Grounding must have a fixed, non-removable connection. BTS DC power input must be floating -48 VDC, or positive grounded. Negative grounding is not allowed. Note that the fuse protection does not work with negative grounding. Note also that surge and lightning protection may not work properly with negative grounding. In a +24 VDC system, a Flexi Power DC/DC Module (FPDA) or a similar safety-approved DC/DC converter must be used to convert the negative grounded +24 VDC to floating -48 VDC g Follow local requirements for earthing (grounding). The principles and requirements vary in different countries. Observe the following recommendations when planning the BTS grounding: • Grounding cable cross-section has to be more than any of AC or DC power feeding cable cross-section. • The grounding cable is connected with screws to the BTS mains grounding point. • The grounding cable must be connected to a main grounding busbar with a minimum of 6 mm2 (10 AWG) grounding cable. • Route the grounding cables as directly as possible from the equipment to the grounding point. Avoid unnecessary loops and sharp bending of the grounding cable. The grounding cables should not be run parallel with power cables. Issue: 04 DN0951839 71 Power requirements Flexi Multiradio Base Station Installation Site Requirements • The external antenna feeders must also be grounded according to the local legislation if the antennas are exposed to lightning. • The BTS is suitable for installation in a Common Bonding Network (CBN), Isolated Bonding Network (IBN) or both. 7.2 Mains power requirements f WARNING! Danger of lethal voltages. Make sure that the mains power breaker is off, and that the cabinet is properly earthed (grounded), before connecting or removing any mains power supply cables from the BTS cabinet. At the site there must be a main switch for disconnecting the BTS mains power. The disconnecting device should disconnect both input supply poles simultaneously. Table 46 Permitted operating voltage Property Nominal operating voltage Permitted operating voltage DC voltage 48 VDC 40.5 to 57.0 VDC AC voltage with 200 - 240 VAC 184 to 276 VAC (45 - 66 Hz) optional FPMA DC voltage with 24 VDC 18 to 32 VDC optional DC Module DC return connections can be isolated DC return (DC-I) or common DC return (DC-C). Check the power consumption. If the power demand exceeds 30A and you use a 30A source such as an integrated power distribution unit (PDU) or System Module Power Output port with 30A output capability, then it is recommended to use the dual power cable FPCA (472806A) with the PDU or System Module Power Output port. See Cabling Flexi Multiradio BTS LTE for instructions on how to connect the dual power cable. g Note that there are some variations in input voltages between different RF variants. For more information, see RF Module and Remote Radio Head power requirements in Flexi Multiradio BTS RF Module and Remote Radio Head Description. 7.2.1 Circuit breakers General guidelines for circuit breakers are provided below. Recommended sizes are provided in Table Recommended sizes for circuit breakers. • Medium delay type (B or C) is recommended to avoid tripping in rush current or minor lightning surges. 72 DN0951839 Issue: 04 Flexi Multiradio Base Station Installation Site Power requirements Requirements • Circuit breaker interrupt rating is recommended for exceeding maximum short circuit (breaking) capacity expected from the power source. • Voltage rating for overvoltage protection device should also be considered.

In a BTS site with AC feed only, Flexi Power Module (FPMA) is required to convert AC to DC. Flexi Power Module (FPMA) consists of mechanics, AC terminal, and four slots for AC/DC sub-module (FPAA) or battery sub- module (FPBA/B). Two FPMAs can be installed in a stack to support FPAA and FPBA/B operating in parallel. Table 48: Battery backup times shows the battery backup times depending on configuration and load scenario. 76 DN0951839 Issue: 04 Flexi Multiradio Base Station Installation Site Power requirements Requirements Table 48 Battery backup times FPMA Estimated typical battery backup time in 23°C for new battery [min.] Single FPMA Dual FPMA (stacked) Rectifying FPAA 1 x FPBA/B 2 x FPBA/B 3 x FPBA/B 4 x FPBA/B 5 x FPBA/B 6 x FPBA/B capacity [W] (rectifier) (battery) (battery) (battery) (battery) (battery) (battery) 250 1 32 64 96 128 160 192 500 1 16 32 48 64 80 96 750 1 11 22 33 44 55 66 1000 1 8 16 24 32 40 48 1250 2 - 13 19 26 32 38 1500 2 - 11 16 21 27 32 1750 2 - 9 14 18 23 27 2000 2 - 8 12 16 20 24 2250 3 - - 11 14 18 - 2500 3 - - 10 13 16 - 2750 3 - - 9 12 15 - 3000 3 - - 8 11 13 - 3250 4 - - - 10 - - 3500 4 - - - 9 - - 3750 4 - - - 9 - - 4000 4 - - - 8 - - g FPBA/FPBB maximum charge and heating power is 100 W per battery. The “per battery” charge power needs to be taken into account and subtracted from the available rectifying capacity, thus reducing the power available for the BTS. In redundant (n+1) configurations an extra FPAA provides rectifying redundancy and, additionally, takes care of battery charging.

ESMx consumption (including the FIxx transmission card) 2. RF Module/RRH idle consumption (with no RF output) 3. Branch (or pipe) level consumption The same applies for BTS power consumption when RRH (FHxx) is used. Note that RRH has 2 branches, each branch has one TX/RX antenna. The branch level consumption varies for different configurations and depends on factors such as "per TRX power" setting and number of active time slots. BTS heat dissipation can be estimated by subtracting total TX power from total BTS intake power. The BTS power consumption figures given below are measured under the following conditions: • Based on the measurements taken with ESMB/C, RF Module (FXxx) and RRH Module (FHxA) with BTS SW EX3.1 MP1.0 and EX3.1 PP2.1. • Power Level (PL) =0 (maximum power), room temperature, dedicated 2G mode with GMSK modulation, 54 VDC power supply, Optimized Cooling profile (default). • Measurements done in BTS Network Mode (under BSC control), TCH TRX(s) activated via 2G Flexi BTS Site Manager menu ‘Test’ and ‘TRX Continuous Transmission’ (activates all timeslots). • The RF Module idle consumption measured when BTS (sector) or BCF object is locked on BSC. • Fans rotating at typical speed at room temperature. The maximum fan speed can increase module level power consumption by 20 W. Note that RRH modules use convection cooling and do not have fans. g The following BTS level power consumption values are an estimate and a tolerance of ±10% compared to a real measured value is expected.

The inner parts of the Citytalk cabinet must be stripped out before Flexi BTS modules are installed, and certain parts of the Citytalk cabinet is to be replaced with new parts belonging to the Talk Conversion Kit. Standard Citytalk installation tools can be used for stripping out the cabinet. The Citytalk cabinet retains its outline dimensions and the mechanical shape when modified with the Talk Conversion Kit. The Flexi BTS within the modified cabinet fulfills the Flexi BTS temperature and environmental requirements. g To reduce the risk of temperature alarms or power reduction, average power across all TX branches should be limited to 60 W or less (or 4 kW total power consumption for all modules in cabinet) for ambient temperatures 46-55ºC (114.8-131ºF). Temperature alarms are based on internal module sensors. 110 DN0951839 Issue: 04 Flexi Multiradio Base Station Installation Site Third-party cabinet requirements Requirements 10 Third-party cabinet requirements Basic requirements for a third-party cabinet The basic requirements for a third-party cabinet are the following: • 19-inch cabinet with supporting side trays or plates (must meet the IEC 60297 Dimensions of mechanical structures of the 482.6 mm (19 in.) series standard) f In cabinet installations, Flexi Multiradio module casings are needed to ensure proper cooling and support for the module cores. When installing modules in a third-party cabinet, do not remove the module cores from their casings. • Minimum depth 600 mm (23.6 in.) • Rear air intake (Make sure that input air is evenly distributed between the installed modules.) • Front exhaust • Proper cable routing • The recommended constant ambient temperature for modules installed inside the cabinet must be -35ºC - +45ºC (-31ºF - +113ºF) • If the installation is a stand-alone rack (and no cabinet), NSN requires that the front and the rear covers are used for safety purposes. A casing is required to mount the rear cover. For more information on the third-party cabinet installations, see Installing modules inside a third-party cabinet in the Installing Flexi Multiradio Base Station and Flexi Multiradio 10 Base Station Modules in Cabinets document. Requirements for Flexi Multiradio BTS and Flexi Multiradio 10 Base Station module level cooling in a third-party cabinet Flexi BTS module is installed in the cabinet without the rear-side and front-side plastic covers. The air volume flow requirement and pressure drop caused by the cabinet back wall and front wall (door) for a single Flexi BTS module vary with module version, see Table 82: Air volume flow and cabinet pressure drop. The module cooling fans’ minimum distance to any obstacle in the rear side of the cabinet is 40 mm (1.6 in.). When planning site cooling, BTS power consumption must be taken into consideration.

DN70117692 The entire cabinet volume flow is dependent on the number of modules used (for example, if three Release 1 RF Modules are used, the entire cabinet volume flow is 420 m3/h (3*140 m3/h) and the pressure drop caused by the front and rear door maximum 25 Pa). All modules must receive cool ambient air, and the circulation from the front of the module to the rear side of the module must be prevented. There must be sufficient distance to the wall (or any other obstacle) in the rear side of the cabinet, so that the required airflow rate (for example 140 m3/h) is reached in all modules used. It is recommended that the module cables be routed so that they do not prevent the air outflow from the BTS. 112 DN0951839 Issue: 04 Flexi Multiradio Base Station Installation Site 19-inch open rack requirements Requirements 11 19-inch open rack requirements 19 in. Open Rack is designed for the installation of the Flexi modules in Indoor sites. Figure 35 19-inch open rack Basic requirements are listed below: • temperature range: -35ºC - +55ºC ( -31ºF - 131ºF) • minimum depth 600 mm (23.6 in.) • humidity resistant • RoHs compliance with the directive 2002/95/EC that requires that all new electrical and electronic equipment put on the EU market from July 1 2006 do not contain lead, mercury, cadmium, PBB and PBDE. • In a stand-alone 19 in. racks installations front and back covers must be installed for safety purposes. Since the cable support plate of the cable entry assembly does not fit into the rack, some modifications are required to the cable entry assembly.
