Routing cables out of a cabinet
Route cables through the top or bottom of a cabinet, depending on your
installation.
Procedure steps
1 Remove the smaller grill cutout in the top or bottom of the cabinet with a
3/8-in. box wrench.
2 Route each cable through the cutout into the channels in the cable guide.
The smaller channels in the cable guides are for fiber optic cables. See
the figure “Cable routing through the top or bottom of a cabinet”
(page 400).
3 Label all processor card cables near the connector to indicate the node
name, slot number of the processor card, port number, and whether it is
a receive or transmit cable.
4 Secure the cable to the sides of the cabinet at intervals to ensure proper
airflow around the shelves. Always ensure you do not pinch cables,
especially fiber cables.
After you connect cables between endpoints, you may want to cluster
groups of cables together.
