Fix

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:(IS A SITE ENGINEER AVAILABLE?)

General Sun X86 Blade servers hardware knowledge.

TIME ESTIMATE: 60 minutes.

TASK COMPLEXITY: 1

DELIVERY REQUIREMENT: Immediate, during a maintenance window.


FIELD ENGINEER INSTRUCTIONS

PROBLEM OVERVIEW: Replace a Sun Blade X8400/X8420/X8440 Memory Module

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?
This replacement can not be performed with the system being online.
This replacement implies a complete shutdown and power off of the server.
Replacement during a maintenance window is required.

X8400/X8420/X8420 Server Module Memory Module Configuration Rules:

For X8400
Each X8400 CPU supports up to 4 DIMMs
All X8400 DIMMs must be populated in pairs, for example:
DIMM pair 0 = DIMM slots 0 and 1. These DIMM slots are the farthest slots from the respective CPU.
DIMM pair 1 = DIMM slots 2 and 3. These DIMM slots are the nearest slots to the respective CPU.
If the CPU has only a single DIMM pair, then you must install that single DIMM pair into the farthest slot locations from the respective CPU, which are slots 0 and 1.

For X8420
Each X8420 CPU supports up to 4 DIMMs.
All X8420 DIMMs must be populated in pairs, for example:
DIMM pair 0 = DIMM slots 0 and 1. These DIMM slots are the nearest slots to the respective CPU.
DIMM pair 1 = DIMM slots 2 and 3. These DIMM slots are the farthest slots to the respective CPU.
If the X8420 CPU has only a single DIMM pair, then you must install that single DIMM pair into the farthest slot locations from the
respective CPU, which are slots 2and 3.
All X8420 DIMM pairs must be identical with respect to manufacturer, size, and speed.

For X8440
Each X8440 CPU supports up to 8 DIMMs
All X8440 DIMMs must be populated in pairs, for example:
2-DIMM = DIMM pair 3 (DIMM slots 6 and 7 installed)
4-DIMM = DIMM pairs 2 and 3 (DIMM slots 4, 5, 6, and 7 installed).
6-DIMM = DIMM pairs 1, 2, and 3 (DIMM slots 2, 3, 4, 5, 6, and 7 installed)
8-DIMM = DIMM pairs 0, 1, 2 and 3 (DIMM slots 0, 1, 2, 3, 4, 5, 6,and 7 installed
If the X8440 CPU has only a single DIMM pair, then you must install that single DIMM pair into the farthest slot locations from the respective CPU, which are slots 6 and 7.
All X8440 DIMM pairs must be identical with respect to manufacturer,size and speed.


WHAT ACTION DOES THE ENGINEER NEED TO TAKE:
A. Removal of the faulty Memory DIMM
A.1 Power off the server. Recommendation is to leave this to the customer.
A.2.Pull out the server out from the Chassis.
a. Press together and hold green ejector buttons
b. Open ejector levers by rotating them out from server module
c. Pull server module out. Put it on antistatic surface
A.3 Remove the server module cover by performing the following steps:
a. Place the server module on a stable, antistatic work surface. For example, place the server module on top of an antistatic mat; or, place the
server module on top of the server module™s plastic packaging.
b. Remove Screws holding cover in place, Using a Phillips screwdriver, remove the four middle cover screws and fully loosen the four captive screws.
c. Slide the cover up until the cover clears the tabs at the front of the server module, then remove the cover.
A.4 Locate and attach the antistatic wrist strap. Follow instructions provided with the wrist strap.
A.5 Locate and unpack the new DIMM pair from its antistatic container.
A.6 To remove a DIMM:
a. Rotate both DIMM slot ejectors outward as far as they will go. The DIMM is partially ejected from the socket.
b. Carefully lift the DIMM straight up to remove it from the socket.
c. To Remove the second DIMM, repeat Steps a and b.

A.7 To install a DIMM:
a. Ensure that the DIMM ejector levers are open (angled outward) then align the DIMM notch to the DIMM connector key.
b. Using both thumbs, press the DIMM straight down into the DIMM connector slot until both ejector levers close, locking the DIMM in the DIMM connector slot.

Note The DIMMs must be inserted evenly, straight down into the DIMM connector slot, until the ejector levers lock into place.

c. Verify that the DIMM ejector levers are upright, seated, and tight. Press on the ejector levers to ensure that they are engaged properly.
d. To install the second DIMM, repeat Steps a through c.
A.8 To reinstall the server module cover, slide the cover under the tabs at the front of the server module, then reinstall and tighten all screws.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
Boot up of the server.
Use the ILOM component tab to check any fault.
