Procedure steps
NN10600-175 6.1S2
Remove a Nortel Networks Multiservice Switch 7420 to redeploy in another
location or to decommission.
CAUTION
Risk of equipment damage
You need two people to remove a Multiservice
Switch 7420 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.
Remove the power cables and processor cards and disconnect cables from any
rear-mounted termination panels before removing the shelf.
1 If the device is installed 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 "Rack-mounting brackets on
Multiservice Switch 7420" (page 423)
2 If the device is a vertical mount, remove the shelf plate, shelf assembly
and cable guide as show in the figure "Removing vertical mount shelf
hardware" (page 424).
3 If the device is a desk-top mount, remove the feet and cable guide. See
the figures "Removing the feet on a desk-top mounted Multiservice
Switch 7420" (page 425) and "Cable guide on desk-top mounted
Multiservice Switch 7420" (page 266).
4 Remove any rear-mounted termination panels from the shelf, if no longer
required.
