UID LED Indicator (LED1)
A UID LED is located at LED1. The front UID LED is located on the front panel. When you
press the UID switch, both rear LED1 and front UID LED indicators will turn on. Press the
UID switch again to turn off the LED indicators. Use this UID Indicator to 'mark' the system,
so the system can be easily identified whether on the front or back (e.g., a system rack with
multiple units installed).

and the onboard power status is ok. Turn off the system and unplug the power cord before
