Checklist for Monitoring Redundant MCSs
Purpose 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 “Checklist for Monitoring the
MCS” on page 455.
Table 151 on page 675 provides a checklist of tasks you perform to monitor redundant
MCSs.
