Monitoring the Power Supply in a Junos Space Appliance

 

Purpose

For optimal performance of the Junos Space appliance, verify the condition of the power supply module or modules installed in the appliance.

Note

Routinely check the LED on the power supply module. The Power Supply Module LED is green when the power supply module is powering the appliance, and amber when the power supply module is on but not powering the appliance (standby mode). If there is a problem with the power supply module, the Hardware Fault LED, located on the front panel of the appliance, starts blinking and an alarm sounds.
