DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED: OPL system training

TASK COMPLEXITY: 2

TIME ESTIMATE: 60 minutes

FIELD ENGINEER INSTRUCTIONS

PROBLEM OVERVIEW:
Motherboard Faulty

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?

A data backup is not a pre-requisite but is a wise precaution.
The customer should conduct an orderly software system shutdown.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

If this is a COD board and running XCP < 1115 a servicemode password should be obtained before the start of maintenance.
Check for COD status using "showboards -va".

A faulted DDC will continue to be faulted after replacing the MBU.  The fault will need to be cleared using "clearfault".  XCP < 1115 will need to obtain a servicemode password before performing the maintenance.

Caution - There is an electrical hazard if power cords are not disconnected. All power cords must be disconnected to completely remove power from server.
1. Power off server.
Turn key switch to Service position, confirm POWER LED is off, and disconnect power cables.
Caution - To prevent equipment rack from tipping, deploy anti-tilt feature, if applicable, before you slide server out of rack.
Note - When drawing out Server to front, release cable tie holding PCI cables on rear of server.
2. Remove top cover.
Deploy rack's anti-tilt features (if applicable), slide
server out of rack, and remove top cover.
Caution - Use proper ESD grounding techniques when handling components.
3. Remove all CPU modules and filler panels.
4. Remove all memory boards.
Caution - Use proper ESD grounding techniques when handling components.
5. Release latch and pull two (2) CPU module baffles out of server
6. Remove eight (8) bus bar screws at front of server using a magnetic screwdriver.
7. Loosen two (2) captive screws in center of motherboard unit to release motherboard unit handles.
8. Pull motherboard unit handles until vertical, unseating motherboard unit from backplane.
Caution - The motherboard is heavy. Two people are recommended to lift the unit.
If the unit is too heavy the memory boards can be removed prior to lifting unit.
9. Lift unit out of server.
The unit has small feet so that it can rest on its bottom without damaging motherboard connectors.
10. Align new motherboard unit feet with rails and lower unit into server.
11. Push motherboard unit handles down until horizontal to seat board.
12. Tighten two (2) captive screws in center of motherboard unit to secure motherboard unit handles in place.
13. Secure eight (8) bus bar screws at front of motherboard unit using a magnetic screwdriver.
14. Install two (2) CPU module baffles and secure with latches.

Securing Server
15. Install CPU modules and filler panels.
16. Install all memory boards.
17. Install top cover.
18. Power on server
Reconnect power cables, verifying state of LEDs, and turn keyswitch to Locked position.
19. If this is a COD board replacement change to servicemode and run "enablecodboard <cmu#>"

20. Confirm hardware fix.
Run programs to be certain all components are mounted again and then boot OS

xscf> showstatus
xscf> showhardconf -M

If the MBU was replaced due to a faulted DDC the fault will remain after replacing the MBU.  The fault will need to be cleared using "clearfault".   Once "clearfault" is run the platform will have to be power cycled for it to take effect.

Note: Please be aware when running XCP1114 the MBU status may become "degraded" and won't be able to be cleared. See doc 1538391.1 for more information.

XCP < 1115 will need to obtain a servicemode password before performing the maintenance.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
Boot system and start application per sys-admin procedure
