Chapter 2 Preparation for Installation

Site Requirements

If you use twisted-pair cable in your plant wiring with sufficient distribution of grounding conductors, the plant wiring is unlikely to emit radio interference. If you exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal when applicable.

If the wires exceed the recommended distances or if wires pass between buildings, carefully consider the effect of a lightning strike in your vicinity. The electromagnetic pulse caused by lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic devices. If you have had problems of this sort in the past, you may want to consult experts in electrical surge suppression and shielding.

Shock and Vibration

Cisco SFS 7000P and SFS 7000D Server Switches have been shock- and vibration-tested for operating ranges, handling, and office vibration and criteria, transportation vibration and criteria, and packaged equipment shock. (See Table A-1 on page A-1.)

Power Source Interruptions

Systems are especially sensitive to variations in voltage supplied by the AC power source. Overvoltage, undervoltage, and transients (or spikes) can erase data from memory or even cause components to fail. To protect against these types of problems, power cables should be grounded properly. Also, place the system on a dedicated power circuit (rather than sharing a circuit with other heavy electrical equipment). In general, do not allow the system to share a circuit with any of the following:

•Copy machines

•Air conditioners

•Vacuum cleaners

•Space heaters

•Power tools

•Teletype machines

•Laser printers

•Facsimile machines

•Any other motorized equipment

Besides these appliances, the greatest threats to a system power supply are surges or blackouts that are caused by electrical storms. Whenever possible, turn off the system and any peripherals, and unplug them from their power sources during thunderstorms. If a blackout occurs—even a temporary one—while the system is turned on, turn off the system immediately and disconnect it from the electrical outlet. Leaving the system on may cause problems when the power is restored; all other appliances left on in the area can create large voltage spikes that can damage the system.

Preventing Electrostatic Discharge Damage

ESD damage, which can occur when modules or other FRUs are improperly handled, results in intermittent or complete failures. Modules consist of printed circuit boards that are fixed in metal carriers. EMI shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the circuit board from ESD, always use an ESD grounding strap when handling modules.
