Route Switch Processor (RSP8) Installation and Configuration Guide
OL-4920-02
Installation Prerequisites
Electrical Equipment Guidelines
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 anyaction 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 Guidelines
Usethe 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 Damage
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are
improperly handled, can result in complete or intermittent failures. Each processor module contains a
printed circuit card that is fixed in a metal carrier.
Electromagnetic interference (EMI) shielding, connectors, and a handle are integralcomponents of the
carrier.Although the metal carrier helps to protect the board from ESD, use an ESD-preventive wrist or
ankle strap whenever you handle any electronic system component.
Following are guidelines for preventing ESD damage:
Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact.
Whenyou workat the interface processor end of the router, connect the equipment end of the strap
to the captive installation screw on an installed interface processor, or to the chassis grounding
receptacle that is located next to each power supply.
When you install a processor module, use the ejector levers to properly seat the bus connectors in
the backplane, and then tighten both captive installation screws. These screws prevent accidental
removal, provide proper grounding for the system, and help to ensure that the bus connectors are
seated in the backplane.
Handle processor modules by the carrier handles and carrier edges only; never touch the board or
any connector pins.
