3-2 Control Panel Buttons
The chassis includes three push-buttons.
UID : Depressing the UID (unit identifier) button illuminates an LED on both the front
and rear of the chassis for easy system location in large stack configurations. The
LED will remain on until the button is pushed a second time. Another UID button
on the rear of the chassis serves the same function.
Power : The main power switch applies or removes power from the power supply
to the server system. Turning off system power with this button removes the main
power but standby power is still supplied to the system.
3-3 Control Panel LEDs
There are five LEDs that provide status information about the system.
Information LED
: Alerts operator of several states, as noted in the table below.

Overheating
There are several possible responses if the system overheats.
Overheat Temperature Setting
Some backplanes allow the overheat temperature to be set at 45, 50, or 55 by
changing a jumper setting. For more information, consult the backplane user manual
at www.supermicro.com. (Click Support, then the Manuals link.)
Responses
If the server overheats:
1. Use the LEDs to determine the nature of the overheating condition.
2. Confirm that the chassis covers are installed properly.
3. Check the routing of the cables and make sure all fans are present and operating
normally.
4. Verify that the heatsinks are installed properly.
