There are two types of checkpoint codes: field programmable gate array (FPGA)

hardware checkpoint codes and UEFI checkpoint codes. The UEFI checkpoint

codes might change because of code sequence and timing changes or when the

server firmware is updated.

v Reset button: Press this button to reset the server and run the power-on

self-test (POST). You might have to use a pen or the end of a straightened paper

clip to press the button. The reset button is in the lower right-hand corner of the

diagnostics panel.

For more information about EasyLED diagnostics, see the Hardware Maintenance

Manual.

The following table lists the LEDs on the EasyLED diagnostics panel and suggested

actions to solve the detected problems.

v Follow the suggested actions in the order in which they are listed in the Action column until the problem

is solved.

v See the parts listing in the Hardware Maintenance Manual to determine which components are customer

replaceable units (CRU) and which components are field replaceable units (FRU).

v If an action step is preceded by “(Trained service technician only),” that step must be performed only by a

trained service technician.

LED Description Action

None, but

the

system-

error LED

is lit.

An error has occurred and cannot be

diagnosed, or the IMM has failed. The

error is not represented by an EasyLED

diagnostics LED.

Use the Setup utility to check the system-event log for

information about the error.

OVER

SPEC

The server was shut down due to a

power-supply overload condition on one

of the power channels. The power

supplies are using more power than the

maximum rating.

1. If any of the 12v power channel error LEDs (A, B, C, D, E,

or AUX) on the system board are lit also, see “Power

problems” on page 138. (See “System-board LEDs” on

page 27 for the location of the power channel error LEDs.)

2. Check the power supply LEDs for an error indication (AC

LED and DC LED are not both lit, or the power-supply error

LED is lit). Swap power supplies 1 and 2 with each other.

v If the error follows the power supply, replace the failed

power supply.

v If the error remains with the power bay, (trained service

technician only) replace the system board.

Remove optional devices from the server.

LOG An error message has been written to

the system-event log

Check the IMM system event log and the system-error log for

information about the error. Replace any components that are

identified in the error logs.

LINK Reserved.

PS A power supply has failed.

1. Check the power supply LEDs for an error indication (AC

LED and DC LED are not both lit). See Table 16 on page

149 for more information.

2. Make sure that the failing power supply is correctly seated.

3. Replace the failed power supply.
