Removing a Cable on an MX2008 MPC or MIC
Removing and installing cables on an MPC or a MIC does not affect router function, except that the
component does not receive or transmit data while its cable is disconnected.
To remove a fiber-optic cable:
1. If the component connects to fiber-optic cable, have ready a rubber safety cap for each cable and
transceiver.
2. If you are removing all cables connected to the component, use one of the following methods to take
the component offline:
To take an MPC offline:
Press and hold the corresponding online button on the craft interface. The green OK 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
Reference.
NOTE:
When you issue the request chassis fpc slot slot-number offline command, the
FRU loses power, and the system's total power increases.
To take a MIC offline:
Press the online/offline button on the MIC. Use a narrow-ended tool that fits inside the opening
that leads to the button. Press and hold the button until the MIC LED goes off (about 5 seconds).
Issue the following CLI command:
user@host> request chassis mic fpc-slot fpc-slot mic-slot mic-slot offline
For more information about the command, see the
Reference.
3. Unplug the cable from the cable connector port. If the MIC uses fiber-optic cable, immediately cover
each transceiver and the end of each cable with a rubber safety cap.
