Device Status LED Behavior
Startup takes approximately one minute to complete. If you want to turn the device off
and on again, we recommend you wait a few seconds between shutting it down and
powering it back up.
There are three device status LEDs located on the left-side of the front panel:
•
Power
•
Hard disk access
•
Fault
Table 5 on page 49 lists the name, color, status, and description of each device status
LED.
