Appendix C Repacking the switch
This chapter describes how to repack the switch chassis, power modules, and modules.
Removing cables from the switch
Before repacking the switch, remove all cables such as the power cords, console cable, twisted pair
cables, optical fibers, and grounding cable from the switch.
Removing the power cords
1. Switch off the circuit breakers at the input end of all power cords.
2. Wear an ESD wrist strap, and make sure it makes good skin contact and is reliably grounded.
For more information, see "Attaching an ESD wrist strap."
3. Remove power cords.

For an AC power cord, remove the cable tie, and then remove the power cord connector
from the power module.

For a DC power cord, loosen the screws on the power cord connector, and then remove the
connector from the power module.
4. Perform the same step to remove the other power cords.
Removing the console cable
1. Pull the RJ-45 connector of the console cable out from the console port of the switch.
2. Pull the DB-9 connector of the console cable out from the serial port of the PC or the terminal.
Removing the grounding cable
1. Loosen the two screws at the grounding holes (located at the lower right of the rear panel and
marked with a grounding sign) of the chassis, as shown by callouts 1, 2, and 3 in
FigureC-1 , and
then remove the grounding cable from the chassis.
2. Use a wrench to loosen the hex nut on the grounding post of the grounding strip, and remove
the other end of the grounding cable (with a ring terminal) from the grounding post, as shown by
callouts 4 and 5 in
FigureC-1 .
