Removing a 5-slot Passport switch shelf
Remove a 5-slot Passport switch shelf to replace a failed shelf or when
decommissioning a switch.
Prerequisites
• Remove the power cables and processor cards and disconnect cables
from any rear-mounted termination panels before removing the shelf.
Procedure steps
1 If necessary, disconnect the external alarm cable from the rear of the
switch.
2 If the switch is in a rack or cabinet, have one person remove the screws
that fasten the front brackets to the rails of the rack or cabinet while
another person supports the chassis. Remove the brackets from the
chassis if no longer required. See the figure “Removing the switch from a
rack” (page 348).
3 If the switch is a floor-mounted model, remove the feet. See the figure
“Removing the feet from the bottom of a floor-mounted switch” (page 349)
4 Remove any rear-mounted termination panels from the shelf, if no longer
required.
5 Pack the shelf in its original packaging.
CAUTION
Risk of equipment damage
You need two people to remove a 5-slot Passport switch
from a rack or cabinet: one person must hold the chassis
in place while a second person unfastens the screws.
CAUTION
Risk of damage to equipment by moving
When moving an uncrated cabinet or shelf assembly,
protect it from strain, shock, impact, and vibration. Lack
of protection can damage or warp the equipment.
