Appendix C Repacking the router
Removing cables from the router
Before repacking the router, remove all cables such as the power cords, console cable, twisted pair
cables, optical fibers, and grounding cable from the router.
Removing the power cords
1. Switch off the circuit breakers at the input ends of all power cords.
2. Wear an ESD wrist strap, and make sure it makes good skin contact and is reliably grounded.
3. Remove power cords.

For an AC power cord, remove the cable tie, and then remove the power cord connector.

For a DC power cord, loosen the screws on the power cord connector, and then remove the
connector.
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 on the router.
2. Pull the DB-9 connector of the console cable out from the serial port on the PC or the terminal.
Removing the grounding cable
1. Loosen the two screws from the grounding point at the rear bottom of the chassis, and then
remove the grounding cable from the chassis.
2. Use a wrench to remove the hex nut from the grounding post on the grounding strip, and
remove the other end (ring terminal) of the grounding cable from the grounding post.
Removing the twisted pair cables and optical fibers
You must remove all twisted pair cables and optical fibers from the ports on the router.
NOTE:
After pulling out an optical fiber from a transceiver module, cover the connector of the optical fiber
with a dust cap to keep the connector clean.
