Monitor Redundant MCS Tasks
1. Check the Redundant MCS Environmental
Status on page 678
2. Check the Redundant MCS Status from
the Craft Interface on page 679
3. Check the Redundant MCS LED Status on
page 680
Display Redundant MCS Mastership
1. Check the MCS Environmental Status on
page 457
2. Check the MCS Status from the Craft
Interface on page 458
3. Check the MCS LEDs on page 459
Switch MCS Mastership

Redundant MCSs Overview on page 676
Inspect redundant MCSs to ensure that functions are interrupted, such as component
alarm messages; component power-up and power-down; Routing Engine, MCS, and
PCG mastership control; SONET clock generation and monitoring; and system clock
monitoring.
Redundant MCSs are two MCSs installed in the M40e or M160 router.
The MCS is a component of the host module. Each MCS requires a Routing Engine to be
installed in an adjacent slot.
RE1 . Even if an MCS is physically installed in the chassis, it does not function if there is no
Routing Engine present in the adjacent slot.
Command or Action
show chassis environment mcs
show chassis craft-interface
Check the LEDs on the MCS faceplate.
show chassis environment mcs
show chassis craft-interface
Check the LEDs on the MCS faceplate.
Manually take the MCS offline by pressing the
offline button on the component faceplate.
1. Take the host module offline.
2. Take the MCS offline.
3. Remove the MCS and replace it with one
that you know works.
See "Return the Failed Component" on page
or follow the procedure in the M40e or M160
router hardware guide.
