Horizon II macroBSS12 Operation & Maintenance Objectives State the functional areas of the Horizon II macro cabinet. • Describe the functions and operation of the Horizon II macro Digital modules. • Describe the cabinet RF Components. • Describe the RF Configurations used with the Horizon II macro cabinet. By the end of this chapter the student will be able to :- Site Controller (HIISC) CTU2 Cooling Fans Power Supply Units (PSU) Circuit Breaker Card (CBC) Alarm Board HORIZON II macro Cabinet Front View Site I/O Panel Tx Blocks Link Interface Board SURF2 Power Supply EAS Alarm, PIX 0 & 1 HORIZON II macro Cabinet Top View Power Supply Units Cabinet Power Supply Maximum 4x PSU per cabinet – One for Redundancy Depends on the number of Radios fitted. The Cabinet can support the three types of power supply • +27V (negative earth) • -48V (positive earth) • Nominal 120/240V AC -48v Power Supply Units Power supply unit Power Supply Units All three unit types support the same PSU Alarms: • O/P over/under voltage. • I/P under voltage. • Over temperature. • Internal Fan failure. Circuit Breaker Card (CBC) 6x CCB for CTU2 2x Push Button HIISC 2x Push Button SURF2 1x Tx RF Blocks 1x FAN trays Temperature control Cabinet Temperature Control • Operating range -5 C to +45 C • Three Internal FAN units – speed controlled • 3x Cabinet Temperature Sensors – » 1x (70 C) for cabinet alarm » 2x (85 C) to shutdown the cabinet, reset at 55 C. Cabinet Fan unit Alarm Module Cabinet Alarm Module • Collects All internal Cabinet Alarms • Controls the PIX connection (customer external alarms) • Process Antenna VSWR alarms Note: NOT backwards compatible to the Horizonmacro cabinet Alarm Board Mains Door 1 LVD Fan 0 Fan 1 & 2 ALL LEDs are GREEN when the equipment is OK RED when equipment is faulty Only 4x active Displays HorizonII Site Controller (HSCII) Horizon II Site Controller (HIISC) • Performs functions of: MCUF, NIU, FMUX and BPSM in Horizonmacro cabinet. • Cabinet supports 2x HIISC cards Master/Slave ( redundancy) • Compact Flash card (32 Mbyte memory) Status LEDs •States LEDs – GREEN (normal operation) RED (Fault). Compact Flash Slot •Compact Flash Card slot – contains 32Mb of memory. TTY MMI •TTY MMI – connection for 9 pin D type connector. Reset Buttons Reset Buttons CPU – is a Soft Reset (Reset Controllers Main Processors. Software remains in RAM). FULL – is a Hard reset. Removes software from memory. CAL Port •CAL PORT – Calibrates the Sync Block. The 8K Reference is used in GCLK calibration. NIU Ethernet Port Synch/NIU TTY PORT •The NIU Ethernet and SYNC/NIU TTY Port are for factory use only.
