 Netra 240 - How To Remove and Replace Netra 240 Memory DIMM

Fix

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

Netra 240 product training is desirable but not required, as the part is a CRU

TIME ESTIMATE: 45 mins

TASK COMPLEXITY: 1

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: Memory Faulure - Faulty Memory Dimm/s

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?:

The following procedures describe how to remove and install individual Memory Dimms into the Netra 240 server.
Memory Modules

There are eight DIMM slots on the system board, with four DIMM slots adjacent to each CPU socket. Because memory is installed as matched DIMM pairs, these slots are divided into two DIMM banks per CPU. Therefore, CPU0 has four corresponding DIMM slots divided into two banks, Bank0 and Bank1. CPU1 has four corresponding DIMM slots divided into two banks, Bank0 and Bank1.

Memory Configuration Rules

When you install memory, follow these configuration rules:

All memory must be installed on the system board as matched DIMM pairs, where each DIMM in the pair shares the same characteristics.
All DIMM pairs on the system board must share the following characteristics:
   - Vendor
   - Type
   - Capacity
   - Speed

On a single-processor system board, install the first DIMM pair in the memory bank next to the CPU. For example, on a single-processor system board, the CPU is installed in the CPU0 slot. Therefore, you must install the first DIMM pair in CPU0 DIMM Bank0.  

A dual-processor system board must have a minimum of one DIMM pair installed in CPU0 DIMM Bank0

Removing Memory Modules

1. Power off the server.

2. Remove the server cover.

3. Open the rotating service module.

4. Ensure that the server is properly grounded.

5. Rotate the air duct and rear fan assembly up.

 - Note that you only have to rotate the assembly up, not remove it from the server.

6. Press down on the latches at the sides of the memory socket.

7. Remove the memory module from the socket.

Installing Memory Modules

1. Prepare the server for servicing, if you have not done so already:

a. Power off the server.

b. Remove the server cover.

c. Close the rotating service module.

d. Ensure that the server is properly grounded.

e. Rotate the air duct and rear fan assembly up.

 - Note that you only have to rotate the assembly up, not remove it from the server.

2. Locate the correct memory socket

3. Ensure that the socket latches are open.

4. Press the memory module in the memory socket.

5. Press down until the socket latches snap into place.

6. Close the air duct and rear fan assembly.

7. Close the rotating service module.

8. Install the server cover.

9. Power on the server.

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

Bring system back up to a functioning state.
Restart software applications per applicable administration guides to resume system operation.
