Routing card cables on a Multiservice Switch 7460
Route processor card cables through the Nortel Networks Multiservice
Switch
7460 cable management bracket, to keep them organized.
Procedure steps
1 Route the cables from the faceplate of each processor card through the
cable management bracket as shown in the figure “Cable path from
processor cards in a Multiservice Switch 7460” (page 515).
Processor card cables are intended to be routed to the left side of the shelf
to accommodate offset connectors. If you route any cables along the right
side of the shelf, you must ensure that they do not reduce or restrict the
intake airflow from the right.
2 Label all processor card cables near the connector to indicate the node
name, slot number of the processor card, port number, and if it is a receive
or transmit cable.
3 Secure cables to the sides of the cabinet away from the side of the shelf
assembly to ensure unrestricted or unreduced exhaust airflow from the
left side of the shelf assembly. The shelf requires a minimum air flow
space of 5
cm (2 in.) on each side of the shelf.
When dressing cables, always ensure that you do not crimp, pinch, snag,
or over bend cables, especially fiber cables. The bend radii of cables is
provided in NN10600-170 Nortel Networks Multiservice Switch 7400
