Monitoring CMM Modules
Front Panel LEDs
The CMM provides a series of status LEDs on the module’s front panel. These LEDs offer basic status
information for the following switch functions:
• CMM hardware operation (OK1)
• System software (OK2)
• CMM redundancy (PRI and SEC)
• Chassis ambient air temperature (TEMP)
• Fan status (FAN)
• Ethernet management port (LINK and ACT)
Refer to page 4-3 for detailed information on CMM front panel LEDs.
Accessing General CMM Information
The switch’s Command Line Interface (CLI) offers CMM monitoring commands. These commands allow
you to access general CMM hardware information as well as the current operating status of CMM-related
components.
