UID Switch and LED Indicator (UID LED & UID-SW)
The rear UID LED is located next to the UID switch. The front UID LED is located on the front
panel. When you press the UID switch, both rear 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).
BMC Hearbeat LED (LEDM1)
A BMC Heartbeat LED is located at LEDM1 on the motherboard. When LEDM1 is blinking,
the BMC is functioning normally. See the table below for more information.
