10.1
Post Code Diagnostic LEDs
A bank of eight POST code diagnostic LEDs are on the back edge of the server next to the Serial Port A
connector. During the system boot process, the BIOS executes many platform configuration steps, each of
which is assigned a specific hexadecimal POST code number. As each configuration step is started, the BIOS
displays the given POST code to the POST code diagnostic LEDs. The purpose of these LEDs is to assist in
troubleshooting a system hang condition during the POST process. The diagnostic LEDs can be used to
identify the last POST process to be executed. See
for a complete description of how these LEDs
are read, and for a list of all supported POST codes.
10.2
System ID LED
The server board includes a blue system ID LED that is used to visually identify a specific server system
installed among many other similar systems.
Note:
In an Intel Server System M50CYP2UR or M50CYP1UR family, there are two options available for
illuminating the System ID LED:
•
The front panel ID LED button is pushed that causes the LED to illuminate to a solid on state until the
button is pushed again.
•
An IPMI Chassis Identify command is remotely entered that causes the LED to blink.
10.3
System Status LED
The server board includes a bi-color system status LED. This LED indicates the current health of the server.
Possible LED states include solid green, blinking green, solid amber, and blinking amber.
When the server is powered down (transitions to the DC-off state or S5), the BMC is still on standby power
and retains the sensor and front panel status LED state established before the power-down event.
When source power is first applied to the system, the status LED turns solid amber and then immediately
changes to blinking green to indicate that the BMC is booting. If the BMC boot process completes with no
errors, the status LED changes to solid green.
