FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: A Sun Fire X4500 System Controller needs replacement

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

The server does not have a motherboard as a component; however, the I/O controller board and the CPU board together serve the function of a motherboard.

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:

1. Shut down the power from the front panel and then unplug both power supply cords.

2. Remove the cable management assembly if necessary.

2.1 Remove the old system controller.

2.2 Unscrew the captive screw on the system controller handle.

2.3 Pull the system controller out of the chassis.

2.4 Use the handle to pull the system controller from the chassis with one hand while supporting the system controller weight with the other hand.

2.5. Loosen the two captive screws (with plastic green caps) under the system controller handle.

2.6 Remove the system controller cover.

Push the system controller cover toward the rear and lift it off the chassis.

3. Move components to new system controller.

If the DIMMs, CPUs, heat sinks, optional PCI cards, and GRASP board (X4500) are operational and need to be moved to your new system controller, remove them from the old system controller

To install the system controller

1. Place the cover onto the system controller.

2. Hand tighten the two captive screws to secure the cover.

3. Align the system controller with the empty bay in the chassis.

Before replacing the system controller, make sure the cover is installed.

4. Push the system controller into the bay until it firmly engages with the connector on the power distribution board.

5. Push the system controller further until it is seated firmly. Close the system controller handle.

6. Lift the system controller handle until its latch clicks into place.

7. Connect the power cables to both power supplies and make sure to use the power cord retaining clips to keep power cords attached snugly.

8. Replace the cable management assembly if necessary.

9.Update the FRU information using servicetool.

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:Customer to check that the system has initialised correctly after poweron and booted without error.
