Make sure that the power and grounding cables are arranged so that they do not
obstruct access to other switch components.
Routinely check the status LEDs on the power supply faceplates and the craft interface
to determine whether the power supplies are functioning normally.
Check the major and minor alarm LEDs on the craft interface. Power supply failure or
removal triggers an alarm that causes one or both of the LEDs to light. You can display
the associated error messages by issuing the following command:
user@switch> show chassis alarms
Periodically inspect the site to ensure that the grounding and power cables connected
to the switch are securely in place and that there is no moisture accumulating near the
switch.

For optimum cooling, verify the condition of the air filters.
Regularly inspect the air filter. A dirty air filter restricts airflow in the unit, producing a
negative effect on the ventilation of the chassis. The filter degrades over time. You
must replace the filter every 6 months.
CAUTION: Always keep the air filter in place while the switch is operating.
Because the fans are very powerful, they could pull small bits of wire or
other materials into the switch through the unfiltered air intake. This could
damage the switch components.
Use spare filters within one year of manufacture. Check the date of manufacture printed
on the filter. Store spare air filters in a dark, cool, and dry place. Storing air filters at
higher temperatures, or where they can be exposed to ultraviolet (UV) radiation,
hydrocarbon emissions, or vapors from solvents, can significantly reduce their life.
