Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, which occurs when electronic boards or components are
improperly handled, can result in complete or intermittent failures. The processor modules each
comprise 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. The LED board, however,
is not intended to be handled and has no frame or shielding. Handle the LED board by the edges only;
never touch the board components, traces, or connector pins.
Caution
traces, or connector pins.
10 Cisco 7000 and Cisco 7507 Chassis Replacement Instructions
Multimode Fiber Distributed Data Interface (FDDI) connectors use small plastic arms on two
sides of the connector that act like springs and are constrained by the inside of the connector port.
To remove a multimode cable from a FIP port, pinch the two plastic arms inward while pulling
the connector out of the port.
Number 2 Phillips or 3/16-inch flat-blade screwdriver for the captive installation screws on each
processor module. (Most systems use Phillips screws, but some of the earlier systems produced
use slotted screws.)
A 1/4-inch flat-blade or Number 2 Phillips screwdriver to install the power supply. Earlier power
supplies (the first few hundred shipped) have a slotted-head captive installation screw.
ESD-prevention equipment or the disposable grounding wrist strap included with all upgrade kits
Antistatic mat, foam pad, or bag for removed processor modules in case you are not able to
immediately insert them into the new chassis.
Number 2 Phillips screwdriver
3/16-inch flat-blade screwdrivers
Tape measure
Level
One 7/16-inch open-end (or adjustable) wrench if you will remove the chassis feet
Always handle an LED board by the edges only; avoid touching the board components,
