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.

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 IOU

1. Prepare an adequate amount of space to store the contents of the IOU in an orderly manner and prepare labeling materials sufficient for all IO cables attached to the IOU.
    After the procedure all components must be reinstalled in their original order and all cables must be reinstalled in original positions and ports.
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. Label and disconnect all IO cables to the IOU.
Label the cables with their IOU numbers and slot numbers to avoid confusion during the installation steps.

4. Empty all IOU slots.
    Use a grounding strap to protect the equipment from ESD damage. Set the components aside in orderly groups so you can put them back in their proper slots during the installation steps.
    a. Remove the I/O boards
    b. Remove the upper set of eight IO cards and carriers

c. Remove all four EMSs

d. Remove all eight HDDs

e. Remove the lower set of eight IO cards and carriers
f. Remove the two disk cages

5. Remove the IOU.
a. Use a T20 Torx screwdriver to loosen the captive screws on the two extraction levers
b. Fully open the extraction levers.

Caution – The open extraction levers may be easily damaged and might slip down to eye level and pose a physical danger. Once the IOU has been removed, keep the levers closed and locked whenever possible.

c. Pull the IOU out of the cabinet.

Caution – The connectors on the rear of the IOU are easily damaged. Do not rest the IOU on its connectors on a work surface. Rest it on it's side to avoid having it fall over accidently.

d. Close the IOU extraction levers and secure the captive screws.

Install an IOU

1. Use a grounding strap to protect the equipment from ESD damage.
2. Install the IOU.
a. Loosen the captive screws on the two extraction levers
b. Fully open the extraction levers.

Caution – The open extraction levers might slip down to eye level and pose a danger. Keep the levers closed and locked whenever possible.

c. Slowly slide the IOU into its slot. Keep the IOU as perfectly vertical as possible.
When the IOU is almost completely into the slot, stop when you feel some resistance.

Caution – There is a danger of bending pins in the connector at the back of the IOU.
Do not hold the IOU at an angle when inserting it into the slot.

d. Complete the insertion by closing both extraction levers at the same rate so that they both completely close at the same time.

Note – Because of the large number of connector pins at the rear of the IOU, it is normal to feel a larger than normal resistance as you seat the IOU. If you are not sure that you inserted the IOU at the proper angle (exactly 90° to the midplane), pull the IOU out and inspect the connector sockets and pins for damage. If there is no damage, try inserting the IOU again.

e. Use a T20 Torx screwdriver to tighten the captive screws on the extraction levers.

3. Fill the IOU slots.

Note – Install all components in their original locations.

a. Install the two HDD disk cages.

e. Install the upper eight CARs.

4. Install the IO cables. Leave some slack in the cables to allow the cables to be moved aside when necessary.
5. Turn on AC power to the server.
6. Restart the server.
7. Return the faulted component to Oracle.
