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. This feature is only supported on the SSR400 and SSR440 platforms.

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.

CLI Commands

The following show commands allow you to see the chassis status from the CLI.

note

The following commands are only available on the SSR400 and SSR440 platforms. While they are visible on other platforms, they do not provide data. When executed, they return an error and state they are intended for the SSR400 and SSR440 platforms.

CLI Command	Function
show chassis	Display information about the chassis
show chassis firmware	Show information about the chassis firmware
show chassis hardware	Show information about the chassis hardware
show chassis led	Show the status of the chassis LEDs
show chassis led phy	Show the status of the port LEDs
show chassis led system	Show the status of the System LED
show chassis power	Show chassis power
show chassis temperature	Show chassis temperature sensor readings
