Power Problems

 

 

 

Symptom

 

FRU or Action

 

 

The device does not power up.

1. Verify the following items:

 

 

a. The power AC LEDs are on.

 

 

b. The power cables are properly connected to the device.

 

 

c. The electrical outlet functions properly.

 

 

d. The type of memory installed is correct.

 

 

e. If you just installed a hardware option, remove it, and restart

 

 

the device. If the device now powers up, you might have

 

 

installed more hardware options than the power supply

 

 

supports.

 

 

2. If LEDs for CPUs or VRMs are on, verify these items:

 

 

a. A VRM is populated for each microprocessor.

 

 

b. All microprocessors have identical cache sizes, dock speeds,

 

 

and clock frequencies.

 

 

c. Override the front panel push button by turning on switch 7

 

 

of SW1; if power comes on, then there is a service processor

 

 

error and the power reset card needs to be replaced.

 

 

3. See the “Undetermined Problems” section on page 5-25.

 

 

The device does not power

1. Determine whether you are using an ACPI 1or non-ACPI

down.

 

operating system. If you are using a non-ACPI operating system:

a.Press Ctrl+Alt+Delete.

b.Power down the system by holding the power control button for 4 seconds.

c.If the device fails during BIOS POST and the power control button does not work, remove the AC power cord.

2.If the problem remains or if you are using an ACPI-aware operating system, suspect the system board.
