Installation Prerequisites
Safety
Following are safety guidelines that you should follow when working with any equipment that
connects to electrical power or telephone wiring.
Electrical Equipment
Follow these basic guidelines when working with any electrical equipment:
• Before beginning any procedures requiring access to the chassis interior, locate the emergency
power-off switch for the room in which you are working.
• Disconnect all power and external cables before moving a chassis.
• Do not work alone when potentially hazardous conditions exist.
• Never assume that power has been disconnected from a circuit; always check.
• Do not perform any action that creates a potential hazard to people or makes the equipment
unsafe.
• Carefully examine your work area for possible hazards such as moist floors, ungrounded power
extension cables, and missing safety grounds.
Telephone Wiring
Use the following guidelines when working with any equipment that is connected to telephone
wiring or to other network cabling:
• Never install telephone wiring during a lightning storm.
• Never install telephone jacks in wet locations unless the jack is specifically designed for wet
locations.
• Never touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
• Use caution when installing or modifying telephone lines.
Preventing Electrostatic Discharge (ESD) Damage
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are
improperly handled, results in complete or intermittent failures. The EIP comprises a printed circuit
board that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding, connectors, and
a handle are integral components of the carrier. Although the metal carrier helps to protect the board
from ESD, use a preventive antistatic strap whenever handling the EIP. Handle the carriers by the
handles and the carrier edges only; never touch the boards or connector pins. Following are
guidelines for preventing ESD damage:
• Always use an ESD wrist or ankle strap and ensure that it makes good skin contact and connect
the equipment end of the strap to a captive installation screw on an installed power supply.
• When installing an EIP, use the ejector levers to properly seat the bus connectors in the
backplane, then tighten both captive installation screws. (See Figure 12.) These screws prevent
accidental removal, provide proper grounding for the system, and they help to ensure that the bus
connectors are seated in the backplane.
• When removing an EIP, use the ejectors to release the bus connectors from the backplane. Use
the handle to pull the EIP out slowly while keeping your other hand underneath the carrier to
guide it straight out of the slot.
