Removing an MX480 MPC
When you remove an MPC, the router continues to function, although the MIC interfaces
installed on the MPC being removed no longer function.
An MPC installs horizontally in the front of the router. The MPCs are hot-insertable and
hot-removable. A fully configured MPC can weigh up to 18.35 lb (8.3 kg). Be prepared to
accept its full weight.
To remove an MPC (see
1.
Have ready a replacement MPC or DPC blank panel and an antistatic mat for the MPC.
Also have ready rubber safety caps for each MIC using an optical interface on the MPC
that you are removing.
2.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
the strap to one of the ESD points on the chassis.
3.
Label the cables connected to each MIC on the MPC so that you can later reconnect
the cables to the correct MICs.
4.
Use one of the following methods to take the MPC offline:
•
Press and hold the corresponding online button on the craft interface. The green
OK/FAIL
LED next to the button begins to blink. Hold the button down until the LED
goes off.
•
Issue the following CLI command:
user@host>
request chassis fpc slot slot-number offline
For more information about the command, see the Junos OS Operational Mode
Commands.
5.
Disconnect the cables from the MICs installed in the MPC.
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.
6.
If a MIC uses fiber-optic cable, immediately cover each transceiver and the end of
each cable with a rubber safety cap.
