Monitoring Redundant MCS Status on page 570
1. Check the Redundant MCS Environmental Status on
page 571
2. Check the Redundant MCS Status from the Craft Interface
on page 572
3. Check the Redundant MCS LED Status on page 573
You monitor and maintain redundant Miscellaneous Control Subsystems (MCSs)
installed in the M40e or M160 router to ensure that there is no interruption of
functions such as the following:
! Router component monitoring and control for failure and alarm conditions
! Component power-up and power-down control
! Redundant Routing Engine, MCS, and PFE Clock Generator (PCG) mastership
control
! Flexible PIC Concentrator (FPC) error detection and reset control
! SONET clock source generation and monitoring
! SONET reference clock (from the FPC and BIT interfaces) monitoring
! System clocks (from the PCG) monitoring
For more information about monitoring a single MCS, see "Monitoring the MCS" on
page 359.
Table 121 provides a checklist of tasks you perform to monitor redundant MCSs.
