SSR Chassis Manager

The SSR400 and SSR440 support an integrated Chassis Manager to help monitor connectivity, power, temperature, as well as providing insight into other vital operational data.

Chassis Manager​

Interaction with the Chassis Manager is performed through CLI commands and button presses on the front of the SSR400/SSR440 chassis. Components include the LED Manager and Temperature Manager.

LED Manager​

The LED Manager translates status updates from internal SSR components and provides a high level indicator of System Status via the System LED.

The System LED displays the following colors to report system state:

  • Steady Green: Operating normally
  • Amber: Device is starting up
  • Purple: Operation is degraded
  • Red: Error detected in the device

The presence of any major or critical alarms will cause degraded service, resulting in the system LED showing purple. If a Purple or Red LED is seen, use show alarms to view the details of the error or alarm.

Port LEDs have the following behavior to identify port status.

Left LED - Link Activity​

  • Blinking Green: The port and the link are active, and there is link activity.
  • Green On Steadily: The port and the link are active, but there is no link activity.
  • Off: The port is not active.

Right LED - Port Speed​

Port speed is indicated with the following behavior.

  • Unlit: Below 100 Mbps
  • Blinking Green: 100 Mbps (1 blink per second)
  • Green On Steadily: 1000 Mbps

Temperature Manager​

There are three temperature thresholds specified for each sensor:

  • Yellow: A MAJOR alarm is generated, warning of high temperatures, but no action is taken.
  • Red: A CRITICAL alarm is generated, warning of impending critical temperature reached shutdown The CPU is slowed and monitored to reduce heat generation.
  • Shutdown: When the critical temperature threshold is reached, the system generates a fatal error and immediately shuts down the SSR to prevent any damage to the device.

Use show chassis temperature-thresholds to see the thresholds for each alarm level.
