To clean the transceivers, use an appropriate fiber-cleaning device, such as RIFOCS
Fiber Optic Adaptor Cleaning Wands (part number 946). Follow the directions for the
cleaning kit you use.
After you clean an optical transceiver, make sure that the connector tip of the fiber-optic
cable is clean. Use only an approved alcohol-free fiber-optic cable cleaning kit, such
as the Opptex Cletop-S Fiber Cleaner. Follow the directions for the cleaning kit you
use.

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

PEM 0 status:

Make sure that the power and grounding cables are arranged so that they do not
obstruct access to other router components.
Routinely check the status LEDs on the power supply faceplates and the front panel
to determine if the power supplies are functioning normally.
Check the alarm LEDs on the front panel. 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
