Checking The Indicator Lights - IBM Netfinity FASt T500 User Reference

Checking the indicator lights

The controller unit indicator lights display the status of the controller unit and its
components. Green indicator lights mean normal operating status; amber indicator lights
mean a possible failure.
It is important that you check all the indicator lights on the front and back of the controller
unit when you turn on the power. After you turn on the power, the indicator lights might
blink intermittently. Wait until the controller unit completes its power up before checking
for faults. It can take up to 15 minutes for the battery to complete its self-test and up to 24
hours to fully charge, particularly after an unexpected power loss of more than a few
minutes.
Use the following procedure to check the controller unit indicator lights and operating
status.
