Activate a DC Power Supply Module

Perform the following procedure to activate a DC power supply:

1. Verify the power supply operation by checking whether the respective power supply front panel LED

(PS0 or PS1) is green.

2. If the LEDs indicate any issues with power problem, see Troubleshooting.

3. If you are also connecting a redundant DC power supply, repeat these steps for the second power source.

Note

The operating voltage range is -20V to -72VDC.

Port Connection Guidelines

To prevent damage to the fiber-optic cables, we recommend that you keep the transceivers disconnected from

their fiber-optic cables when installing the transceiver in the line card. Before removing a transceiver from

the router, remove the cable from the transceiver.

To maximize the effectiveness and life of your transceivers and optical cables, do the following:

• Wear an ESD-preventative wrist strap that is connected to an earth ground whenever handling transceivers.

• Do not remove and insert a transceiver more often than is necessary. Repeated removals and insertions

If you are connecting a redundant DC power supply, ensure that each power supply is connected to a

separate power source in order to prevent power loss in the event of a power failure.

The router is typically grounded during installation and provides an ESD port to which you can connect

your wrist strap.
