CMM controls and indicators

The Flex System Chassis Management Module (CMM) has LEDs and controls that you can use to obtain status information and restart the CMM.

The CMM has the following LEDs and controls:

Reset button

Use this button to restart the Chassis Management Module. Insert a straightened paper clip into the reset button pinhole; then, press and hold the button in for at least one second to restart the CMM. The restart process initiates upon release of the reset button but might not be immediately apparent in some cases.

Attention

If you press the reset button, hold it for at least 10 seconds, then release it, the CMM will restart and reset back to the factory default configuration. Be sure to save your current configuration before you reset the CMM back to factory defaults. The combined reset and restart process initiates upon release of the reset button but might not be immediately apparent in some cases.

Note

Both the CMM restart and reset to factory default processes require a short period of time to complete.

Power-on LED

When this LED is lit (green), it indicates that the CMM has power.

Active LED

When this LED is lit (green), it indicates that the CMM is actively controlling the chassis.

Only one CMM actively controls the chassis. If two CMMs are installed in the chassis, this LED is lit on only one CMM.

Fault LED

When this LED is lit (yellow), an error has been detected in the CMM. When the error LED is lit, the chassis fault LED is also lit.

Ethernet port link (RJ-45) LED

When this LED is lit (green), it indicates that there is an active connection through the remote management and console (Ethernet) port to the management network.

Ethernet port activity (RJ-45) LED

When this LED is flashing (green), it indicates that there is activity through the remote management and console (Ethernet) port over the management network.
