For optimum router performance, verify the condition of the power supplies.
On a regular basis:
Make sure that the power and grounding cables are arranged so that they do not
obstruct access to other router components.
The power supplies require an unobstructed airflow at both the front and rear of the
chassis. Periodically check the site to ensure that both the air intake at the bottom
front of the chassis and the exhaust from the power supply faceplates are unobstructed.
Periodically inspect the site to ensure that the grounding and power cables connected
to the router are securely in place and that no moisture is accumulating near the router.
To review grounding and site wiring requirements for the router, see
