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: 60 mins

TASK COMPLEXITY: 2

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:
PROBLEM OVERVIEW: Faulty System Board or included component on system board

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?:

Engineer will need to have a 5mm wrench to remove board from system.

The following procedures describe how to remove and install the System Board of a Netra 240 server.

Caution - The assembly might be very hot. Let it cool before beginning this procedure.

Removing the System Board

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. Completely remove the air duct and rear fan assembly.

6. Remove all PCI cards from the PCI riser card assembly.

7. Using a No. 2 Phillips screwdriver, unscrew the two captive screws that secure the PCI riser card assembly to the system board.

8. Pull the PCI riser card assembly straight up to detach it from the system board

9. Disconnect the PDB wiring harness from the system board

10. Lift the SCSI/IDE cable clamp out of the way

 - The clamp has a green cap that is attached to the chassis, and holds the SCSI interface cable and the IDE cable.

11. Disconnect the interface board SCSI and IDE cables from the system board

12. Disconnect the front fan assembly cables from the system board connectors

13. Remove the Hardware Cryptographic Module.

14. Unscrew and remove the DB-9 and SCSI jackposts on the server back panel (using the 5mm wrench)

15. Unscrew the two screws and remove the PCI card support.

16. Remove the ten screws that secure the system board to the bottom of the chassis.

17. Lift the front of the system board slightly and slide the system board toward the front of the chassis so that the SCSI, Ethernet, and serial connectors come free from the chassis.

18. Lift the system board out of the chassis.

Installing a System Board

Caution - The system board ships with CPU heat sinks containing fans. Before installing the replacement system board into the Netra 240 server chassis, you must first remove the fans from the CPU heat sink assemblies.

1. Place the replacement system board on a clean, static-free worktable.

2. Locate the CPU heat sink assemblies on the system board

 - Depending on your system board FRU, there are either one or two CPU heat sink assemblies.

3. Detach the fan power cable connectors from the system board

 - Follow the fan power cables from the fans to the cable connectors on the system board.

Note - The connectors for the CPU0 heat sink fans are labeled P0 F0 and P0 F1. The connectors for the CPU1 heat sink fans are labeled P1 F0 and P1 F1.

4. Unlock the heat sink from the CPU socket by first pressing down on the fasteners securing the heat sink assembly and then lifting them up.

 - Repeat this step for both fasteners on the heat sink.

5. Carefully pull the heat sink up from the CPU socket.

6. Using a No. 1 Phillips screwdriver, remove the screws securing the fans to the heat sink and remove the fans.

 - Two screws secure each fan. Set the fans and screws aside after removing them from the heat sink.

7. Carefully replace the heat sink on the CPU socket, and secure the heat sink by first attaching the rear clips and then pushing down the two front fasteners to the CPU socket.

8. If your system board has two CPU heat sinks, repeat Step 3 through Step 7 for the second heat sink.

9. Position the new system board so that the SCSI, Ethernet, and serial connectors are firmly positioned in their slots at the rear of the chassis and insert the board into the chassis.

10. Install all ten of the system board screws.

 - Do not put any screws in the holes for the PCI card slide retainer. These holes are identified by a circle printed around their circumference.

11. Replace the PCI card support and install the two screws that secure it.

 - Ensure that the arrow embossed on the slider points to the rear of the server.

12. Install and secure the DB-9 and SCSI jackposts to the server back panel (using the 5mm wrench)

13. Install the Hardware Cryptographic Module.

14. Connect the front fan assembly cables to the system board connectors.

Note - Refer to the chassis label for an illustration of the correct routing of the cables.

15. Connect the interface board SCSI and IDE cables to the system board.

16. Press the SCSI/IDE cable clamp back down to secure the SCSI interface and IDE cables.

 - The cable clamp is attached to the chassis and has a green cap.

17. Connect the PDB wiring harness to the system board.

18. Place the PCI riser card assembly in position in the server

a. Press down on the top of the assembly to fully seat it into the system board.

b. Tighten the two captive screws that secure the PCI riser card assembly to the system board.

19. Insert all PCI cards back into the PCI riser card assembly.

20. Install the air duct and rear fan assembly.

21. Close the rotating service module.

22. Install the server cover.

23. 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.
