ESD Caution:

Circuit boards and drives contain electronic components that are extremely sensitive to static electricity. Ordinary amounts of static electricity from clothing or the work environment can destroy the components located on these boards. Do not touch the components along their connector edges.
Use a Antistatic Wrist strap. Attach one end of the strap to your wrist and the other end to the chassis, depending on what type of strap you use, with the adhesive end or the metal plug.
Use an Antistatic Mat. Place ESD-sensitive components such as motherboards, memory, and other PCBs on an antistatic mat.

Contamination Caution:

Dust particles of packaging material are number one cause of datacenter contamination. Make sure to remove all packaging material, up to the ESD safe packaging material, while still being outside the datacenter.

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED: Mx-32 Product Training/Experience

TASK COMPLEXITY: 2

TIME ESTIMATE: 180 minutes COLD replacement

FIELD ENGINEER INSTRUCTIONS

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? : Physical Domains must be shut down. Server must be powered off.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Remove an IO Power Cable Assembly

1. Prepare an adequate amount of space to store the Front Filler Panel and Upper Fan Cage. After the procedure all components must be reinstalled in their original order and all cables must be reinstalled in original positions.

NOTE - remove these steps and add reference to 'how to shut down and power off a M5-32 server' document (when it is created)

2. Halt the server and turn off all AC power.
a. Turn the key switch on the Front Panel of the server to the Service position
b. Use one of the methods to turn off the server:
■ For a graceful shutdown (data will be saved), use one of two methods:
■ Log into Oracle ILOM and issue this command:

-> stop /System

Note this command requires the Oracle ILOM Reset and Host Control (r) user role.
■ Alternatively, momentarily press the On/Standby button on the Front Panel. The SP LED flashes to show that the server and its domains are shutting down.
The other two methods are force methods and should not need to be used.

3. Remove the Front Filler Panel

For instructions, see:

M5-32 How to Service the Front Filler Panel Assembly (Doc ID 1539427.1)

4. Remove the Upper Fan Cage

For instructions, see:

M5-32 - How to Replace a Faulty Upper Fan Cage Assembly (Doc ID 1531620.1)

5. Unlock the I/O Power Cables

There are two metal locking levers on each I/O data cable. The metal locking levers push against plastic locking tabs that are part of the I/O power cable.

a. Push up slightly on the plastic locking tab, then pull down a metal lever.
b. Repeat to unlock the second lever.

6. Remove the T20 Torx screws that hold the upper ends of the red and black power cables to the bus bar assembly.

The I/O power cable assembly includes three red cables and three black cables.
The upper end of each cable is held in place by two screws, for a total of 12 screws for the six cables.

Caution – These are not captive screws.

7. Detach the lower section of the I/O power cable:

Loosen two captive T20 Torx screws that hold the plastic housing of the I/O power cables to the midplane, then pull the assembly out of the midplane.

Note – Do not place screws or other loose hardware on the “shelves” of the midplane. Small items can easily fall inside the cabinet.

Install the IO Power Cable Assembly

1. Use a grounding strap to protect the equipment from ESD damage.

2. Install the lower plastic block of the I/O assembly power cable assembly.

Note – The cable connectors in the plastic block are keyed with flat tops. Align the tops in the plastic block to avoid difficulty inserting the block in the midplane connector. If the block does not insert easily, twist the individual cable ends so that the flat portions of the cable ends are toward the top.

3. Use 12 T10 Torx screws to connect the red and black power cables to the bus bar
assembly.

4. Lock the I/O assembly data cable block to the I/O assembly power cable block.

5. Install the upper fan cage.

For instructions, see:

M5-32 - How to Replace a Faulty Upper Fan Cage Assembly (Doc ID 1531620.1)

6. Install the front filler panel.

For instructions, see:

M5-32 How to Service the Front Filler Panel Assembly (Doc ID 1539427.1)

7. Restart the server.

8. Return the faulted component to Oracle.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

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