Processor

8.2.1

Processor Debug Methodology

1) Enter Setup, startup options, select processor retest – Save and Exit (F10) reset system.

2) Run Platform Diagnostic test (located on Resource CD); if error persists perform the

following checks and steps:

Turn off and remove AC source power; remove top cover and processor air duct.

Reseat DC harness to power pod. Check to see that processor is locked (locking flag

or tab on the side of processor socket is visible).

Check to see that the four processor screws are tightened to 6-inch pounds (Use T-

15 Torx – do not over tighten). If tab is not visible, loosen the four captive mounting

screws and lock the processor (if tab is visible = locked, use 2.5mm Allen clockwise

¼ turn to lock) tighten the four mounting screws replace covers, reconnect AC

source, re-boot / re- run test.

If failure symptom persists:

1. Turn off and remove AC source power; remove top cover and processor air duct.

2. Remove DC power harness from power pod, remove power pod (loosen 4 captive

screws / slide pod away from processor to disengage).

3. Remove and inspect pins on processor (loosen 4 captive screws on processor, turn lock

tab counterclockwise ¼ turn, "tab not visible", lift processor to disengage).

4. Reseat processor and power pod (repeat above steps in reverse order) and re-run tests.

5. Replace / swap power pods or BSP (1st) with APP (2nd) processor.

6. Replace covers, reconnect AC source, restart system.

7. Re-run test in single processor mode (socket 1 must be populated to boot, Socket 2 will

auto terminate).

8.2.2

Processor Component Isolation

If after reseating or swapping component positions, the suspect component cannot be located

(i.e. DC harness, Power pod or Processor) and the failure persists - Replace the main board.
