Components in the line cards are fragile. To extend the lives of your line card cables and
to avoid problems that can result from cable damage, follow these procedures:
To maintain line card cables in switches:
Place excess cable out of the way. Do not allow fastened loops of cable to dangle
from the connector. Placing fasteners on the loops helps retain their shape.
Keep the cable connections clean and free of dust and other particles, which can cause
drops in the received power level. Always inspect cables and clean them if necessary
before connecting an interface.
Label both ends of line card cables to identify them.

For optimum switch performance, verify the condition of the installed power supplies.
On a regular basis:
Check the status of the power supplies by issuing the
command. The output is similar to the following:
