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 Figure 149 on page 347):
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 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 CLI Explorer.
5. Disconnect the cables from the MICs installed in the MPC.
