Maintaining the JRR200 Power System
Maintaining the JRR200 Route Reflector Power Supplies
Purpose
For optimum performance, verify the condition of the power supplies.
Action
On a regular basis:
To check the status of the power supplies, issue the
show chassis environment pem
command. The output shown below is an example.user@host> show chassis environment pem PEM 0 status: State Online Airflow Front to Back Temperature OK DC Output Voltage(V) Current(A) Power(W) Load(%) 12 10 120 18 PEM 1 status: State Online Airflow Front to Back Temperature OK DC Output Voltage(V) Current(A) Power(W) Load(%) 12 10 120 18
Make sure that the power and grounding cables are arranged so that they do not obstruct access to other JRR200 route reflector components.
Routinely check the status LEDs on the power supply faceplates to determine whether the power supplies are functioning normally. Each power supply faceplate displays three LEDs to indicate the status of the power supply.
Check the power LED on the front panel of the device. Power supply failure or removal triggers an alarm that causes LEDs to light. You can display the associated error messages by issuing the following command:
user@host> show chassis alarms
Periodically inspect the site to ensure that the grounding and power cables connected to the device are securely in place and that there is no moisture accumulating near the device.
Replacing the JRR200 Route Reflector AC Power Supply
Each AC power supply is a field-replaceable unit (FRU) installed in the rear panel of JRR200 route reflector. You can remove and replace the power supplies without powering off JRR200 route reflector or disrupting route reflector functions.
All the power supplies must be installed and operational for optimal functioning of JRR200 route reflector.
