Emergenc Power Control A primar power switch that can disconnect all electronic equipment in the data center is specified b NFPA 70 and NFPA 75 (National Fire Protection Association specifications) at each point of entr to the data center. Therefore. All properl installed Sun s stems are grounded through the power cable. However. The batter backup for the UPS should be capable of maintaining the critical load of the data center for a minimum of 15 minutes during a power failure. A properl designed grounding s stem should have as low an impedance as is practicall achievable for proper operation of electronic devices as well as for safet . but in both cases. Power Constraints All servers covered b this guide are shipped with a sufficient number of power supplies to provide all power needed b all Sun supported configurations. Enlist the aid of a qualified electrician to install grounding cables. Use an antistatic wrist strap when working inside the chassis. dedicated ground for the entire power s stem to avoid a ground differential between various grounds.
