2.9 LED Indicators
LAN Port LEDs
The motherboard's Ethernet ports has two LED indicators. The Activity LED is yellow and
indicates connection and activity. The Link LED may be green, amber, or o󰀨 to indicate the
speed of the connection. Refer to the tables below for more information.
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.

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 o󰀨 the LED indicators. Use this UID Indicator to 'mark' the
