Label the cables connected to each MIC on the MPC so that you can later reconnect
3.
the cables to the correct MICs.
Use one of the following methods to take the MPC offline:
4.
Press and hold the corresponding online button on the craft interface. The green
LED next to the button begins to blink. Hold the button down until the LED
OK/FAIL
goes off.
Issue the following CLI command:
user@host>request chassis fpc slot slot-number offline
For more information about the command, see the
Disconnect the cables from the MICs installed in the MPC.
5.
WARNING: Do not look directly into a fiber-optic transceiver or into the
ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable
connected to a transceiver emit laser light that can damage your eyes.
CAUTION: Do not leave a fiber-optic transceiver uncovered except when
inserting or removing cable. The safety cap keeps the port clean and
prevents accidental exposure to laser light.
CAUTION: Avoid bending fiber-optic cable beyond its minimum bend
radius. An arc smaller than a few inches in diameter can damage the cable
and cause problems that are difficult to diagnose.
If a MIC uses fiber-optic cable, immediately cover each transceiver and the end of
6.
each cable with a rubber safety cap.
Simultaneously turn both the ejector handles counterclockwise to unseat the MPC.
7.
Grasp the handles and slide the MPC straight out of the card cage halfway.
8.
Place one hand around the front of the MPC (the MIC housing) and the other hand
9.
under it to support it. Slide the MPC completely out of the chassis, and place it on the
antistatic mat or in the electrostatic bag.
CAUTION: The weight of the MPC is concentrated in the back end. Be
prepared to accept the full weight—up to 18.35 lb (8.3 kg)—as you slide
the MPC out of the chassis.
