Solution

CAP PROBLEM OVERVIEW: Replacing an X4540 System Controller

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED: General HW Service Skills

TASK COMPLEXITY: 1

TIME ESTIMATE: 60 minutes

FIELD ENGINEER INSTRUCTIONS

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

A replacement system controller does not include the CPU, memory (DIMMs), GRASP board (X4500) or Service Processor (X4540), or PCI cards. If these components are good, you must remove them from the old system controller and install them on the replacement system controller.

Suggestion:

You may want to move the CMOS battery from the old system controller onto the new one
Reason is that logistics motherboard which have been shelved for a long time may have depleted battery.

If such a thing is not noticed then this ends up with a PSU_fault led lit and some lines in the system eventlog.
Usually, because of CSAT reasons (directly related to the previous visit) one ends up sending a FSE which costs $$ and another downtime.
Even sending a cmos battery (costs 1$?) is very expensive.

Depending on the TSE this could lead to some confusion and could even end with replacing PSU's or other unnecessary components

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Shut down the power from the front panel and then unplug both power supply cords.
Remove the CMA
Unscrew the captive screw on the system controller handle.
Pull the system controller out of the chassis.
Use the handle to pull the system controller from the chassis with one hand while supporting the system controller weight with the other hand.
Loosen the two captive screws (with plastic green caps) under the system controller handle.
Remove the system controller cover.

To Install the System Controller

Place the cover onto the system controller.
Hand tighten the two captive screws to secure the cover.
Align the system controller with the empty bay in the chassis.
Push the system controller into the bay until it firmly engages with the connector on the power distribution board.
Push the system controller further until it is seated firmly. Close the system controller handle.
Lift the system controller handle until its latch clicks into place.
Connect the power cables to both power supplies and make sure to use the power cord retaining clips to keep power cords attached snugly.
Replace the cable management assembly if necessary.

Update the FRU information using servicetool.
(Refer to MOS Doc 1384913.1 under the References Section, if needed)

Use SSH to log into the sunservice account using the default password changeme
# ssh SP-IP-address -l sunservice SP-IP-address
password: changeme
At the prompt, enter the servicetool command to indicate that you have changed the board

# servicetool --board_replaced=name_of_board

name_of_board is mainboard (that is, the system controller).
service_processor is the X4500 GRASP board or the X4540 system processor.

At the prompt, enter the servicetool command to update the product serial number

# servicetool --fru_product_serial_number
