LED Description Action
IMM2 heartbeat LED Indicates the status of the boot process of
the IMM2.
When the server is connected to power
this LED flashes quickly to indicate that the
IMM2 code is loading. When the loading
is complete, the LED stops flashing briefly
and then flashes slowly to indicate that the
IMM2 if fully operational and you can press
the power-control button to start the server.
If the LED does not begin flashing within 30
seconds of when the server is connected to
power, complete the following steps:
1. (Trained technician only) Recover the
firmware (see “Recovering the server
firmware (UEFI update failure)” on page
143).
2. (Trained technician only) Replace the
system board.
Microprocessor error LED Microprocessor has failed, is missing, or
has been incorrectly installed.
Note: (Trained technician only) Make
sure that the microprocessor is installed
correctly, see “Replacing a microprocessor
and heat sink” on page 242.
1. Check the system-event log to
determine the reason for the lit LED.
2. (Trained technician only) Reseat the
failing microprocessor.
3. Replace the following components one
at a time, in the order shown, restarting
the server each time:
a. (Trained technician only) Failing
microprocessor.
b. (Trained technician only) System
board.
Slot 1 to 2 error LEDs A PCIe slot device has failed or is incorrectly
installed. 1. Check the system-event log to
determine the reason for the lit LED.
2. Remove the slot PCIe device that has
the lit error LED.
3. Reseat the failing device.
4. Replace the following components one
at a time, in the order shown, restarting
the server each time:
a. PCIe device.
b. (Trained technician only) System
board.
System-board error LED System-board CPU VRD and/or power
voltage regulators have failed. (Trained technician only) Replace the
system board.
RTMM heartbeat LED Power-on and power-off sequencing. 1. If the LED flashes at 1Hz, it is
functioning properly and no action is
necessary.
2. (Trained technician only) If the LED is
not flashing, replace the system board.
Power-supply LEDs
This section describes the power-supply LEDs on the rear of the server and the suggested actions to
correct the detected problems.
The following minimum configuration is required for the server to start:
• One microprocessor
• One 1 GB DIMM
• Power supply
