Remove a PIC Cable
To remove a PIC cable, follow this procedure:
1. If the PIC connects to fiber-optic cable, have ready a rubber safety cap for each cable
and transceiver.
2. If removing all cables connected to the PIC, use one of the following methods to
take the PIC offline:
•
Press and hold the PIC offline button until its failure indicator LED lights, which
usually takes about 5 seconds. The failure LED is usually red; for more information,
see the M5 and M10 Internet Routers PIC Guide. The offline button for each PIC is
located below it on the craft interface and is labeled with the PIC slot number.
•
Issue the following CLI command:
user@host>request chassis pic fpc-slot fpc-slot pic-slot pic-slot offline
For more information about the command, see the JUNOS Internet Software
Operational Mode Command Reference: Protocols, Class of Service, Chassis, and
Management.
