Syntax: ge-fpc/pic/port where:

  • fpc: Slot in the router where the MPC is installed

  • pic: 0 (left grouping of 10 ports) or 1 (right grouping of 10 ports) when installed in MIC slot 0; 2 (left grouping of 10 ports) or 3 (right grouping of 10 ports) when installed in MIC slot 1

  • port: 0 through 9

For example, ge-1/3/0 is the interface for port 0 in the right grouping of ports on the MIC installed in MIC slot 1 on an MPC installed in slot 1.

OK/FAIL LED, one bicolor:

  • Green—MIC is functioning normally.

  • Red—MIC has failed.

Link LED, one green per port:

  • Off—No link.

  • On steadily—Link is up.
