DISPATCH INSTRUCTIONS WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED?:

Ultra 5 Workstation product training is desirable but not required

TIME ESTIMATE: 60 mins

TASK COMPLEXITY: 1

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: CPU Module Failure

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 FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE?:

Removing the CPU Module

1. Power off the system, remove the system cover, and attach an antistatic wrist strap

Caution – Use proper ESD grounding techniques when handling components. Wear
an antistatic wrist strap and use an ESD-protected mat. Store ESD-sensitive
components in antistatic bags before placing them on any surface.

Caution – The static random access memory (SRAM) heatsinks are extremely
fragile. Do not touch the SRAM heatsinks.

2. If necessary, remove any PCI cards from PCI slots 1 and 3 to provide clearance.

3. Remove the CPU module as follows:

a. Using a No. 2 Phillips screwdriver, remove the screw securing the hold-down
brace to the riser. Remove the hold-down brace.

b. Using a No. 2 Phillips screwdriver, remove the screw securing the CPU module
hold-down clip to the motherboard. Remove the CPU module hold-down clip.

c. Using your fingers, gently lift the CPU module evenly to loosen it from the
motherboard CPU connectors MJ1 and MJ2.

d. Lift the CPU module upward from the motherboard CPU connectors until it
clears the system chassis.

e. Place the CPU module on an antistatic mat.

Replacing the CPU Module

1. Replace the CPU module as follows:

a. Position the CPU module onto the motherboard CPU connectors MJ1 and MJ2.

b. Grasping the CPU module, gently press on the CPU module rear edges and
then the front edges until the CPU module begins to seat.

c. Using both hands, align the CPU module, then press downward evenly on its
edges until the CPU module is properly seated in the motherboard CPU
connectors.

d. Push the hold-down clip forward over the edge of the CPU module.

e. Replace the hold-down clip. Using a No. 2 Phillips screwdriver, replace the
screw securing the CPU module hold-down clip to the motherboard.

f. Replace the hold-down brace. Using a No. 2 Phillips screwdriver, replace the
screw securing the hold-down brace to the riser.

2. Replace any PCI card(s) removed from slots 1 and 3.

Note – If you upgrade with a replacement CPU module that is faster than 420 MHz,
and the system is using either the Solaris 2.5.1 or 2.6 operating environments,
software patches are required for those Solaris releases to run at the faster CPU
speed. You can order the software patch CDs using part number 704-6657 (for
Solaris 2.5.1) or 704-6658 (for Solaris 2.6). Refer to the patch installation instructions
in the CD-insert document included with the CDs.

3. Detach the wrist strap, replace the system cover, and power on the system.

OBTAIN CUSTOMER ACCEPTANCE WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE TO
RETURN THE SYSTEM TO AN OPERATIONAL STATE:

Restart software applications per applicable administration guides to resume system operation.
