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: M8-8 / M7-8 / M7-16 Product Training/Experience

TASK COMPLEXITY: 4

TIME ESTIMATE: 60 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:

1. Power down the server (requires Oracle ILOM Reset and Host Control (r) user role)

-> stop /System
Stopping the server can take some time, and you must wait until the following message appears on the host(s) console before proceeding to the next step.
-> SP NOTICE: Host is off

2. Remove power using the circuit breakers on the appopriate PDU. Turn breakers off in the following sequence :

For a SPARC M8-8 / M7-8 server:
1. Bottom chassis in rack
  1. R8, R7, R6
  2. L2, L1, L0
2. Middle chassis in rack
  1. R5, R4, R3
  2. L5, L4, L3
3. Top chassis in rack
  1. R2, R1, R0
  2. L8, L7,L6
For a SPARC M7-16 server:
1. R4, R5, L5, L4
2. R0, R1, R2, L8, L7, L6
3. R6, R7, R8, L2, L1, L0

where R indicates the right PDU from the rear of the server, L indicates the left PDU from the rear of the server, and the number represents the PDU group number.

Caution - Because standby power is always present in the server, you must switch off the circuit breakers on the PDUs before accessing any cold-serviceable components.

3. Locate the power module at the rear of the server.

4. Remove all CMIOUs or switch units from the impacted chassis.

Check M8-8 / M7-8 / M7-16 - How to replace a Faulty CMIOU in a CMIOU chassis (Doc ID 1951961.1) for details.
Check M7-16 How to replace a Faulty Switch Unit in a Switch Chassis (Doc ID 1987712.1) for details.

5. Remove the SPs or SPPs and SP tray from the impacted chassis.

6. Unseat the power supplies in the impacted chassis. Check M8-8 / M7-8 / M7-16 How to replace a Faulty Power Supply in a CMIOU chassis or in a Switch chassis (Doc ID 1951408.1) for details.

7. Remove all PDECBs from the impacted chassis. Check M8-8 / M7-8 / M7-16 How to replace a Faulty PDECB in a CMIOU chassis or in a Switch chassis (Doc ID 1952350.1) for details.

8. Remove the Power Module from the CMIOU or Switch chassis

Loosen two T-20 captive screws from the top and bottom of the power module to free it from the chassis.
Slide the power module out of the server.
Place the removed Power Module on an ESD safe surface
Put the removed Power Module into its ESD safe packaging

9. Install the Power Module in the CMIOU or Switch chassis

remove the Power Module from its ESD safe packaging.
Slide the power module part way in and position it with the slot in the side wall.
When the module is about 1inch from being seated in the chassis, locate the spool standoff on the left side and the slot in the chassis side wall. Press the side wall while sliding the module into the chassis to ensure that the spool slides properly into the chassis slot.
Tighten two T-20 captive screws on the top and bottom of the power module to secure it to the chassis.

10. Re-install all the PDECBs to the impacted chassis. Check M8-8 / M7-8 / M7-16 How to replace a Faulty PDECB in a CMIOU chassis or in a Switch chassis (Doc ID 1952350.1) for details.

11. Re-seat the power supplies in the impacted chassis. Check M8-8 / M7-8 / M7-16 How to replace a Faulty Power Supply in a CMIOU chassis or in a Switch chassis (Doc ID 1951408.1) for details.

12. Re-install the SPs or SPPs and SP tray to the impacted chassis.

13. Re-install all CMIOUs or switch units to the impacted chassis.

Check M8-8 / M7-8 / M7-16 - How to replace a Faulty CMIOU in a CMIOU chassis (Doc ID 1951961.1) for details.
Check M7-16 How to replace a Faulty Switch Unit in a Switch Chassis (Doc ID 1987712.1) for details.

14. Switch on PDU Circuit Breakers. Turn breakers on in the following sequence.

For a SPARC M8-8 / M7-8 server:
1. Bottom chassis in rack
  1. R8, R7, R6
  2. L2, L1, L0
2. Middle chassis in rack
  1. R5, R4, R3
  2. L5, L4, L3
3. Top chassis in rack
  1. R2, R1, R0
  2. L8, L7,L6
For a SPARC M7-16 server:
1. R4, R5, L5, L4
2. R0, R1, R2, L8, L7, L6
3. R6, R7, R8, L2, L1, L0

where R indicates the right PDU from the rear of the server, L indicates the left PDU from the rear of the server, and the number represents the PDU group number.

15. As soon as PDU circuit breakers are switched on, standby power is applied, and the SP boots.

Return the faulted component to Oracle.

If the replacement included safety covers on the connectors, install the covers on the component that you are
In the shipping container that contained the replacement component:
1. Using the same material used to pack the replacement component, position the component so that it is not free to move.
2. Add any required paperwork or other documentation in the container.
3. Except when packing CMIOUs, include any tools that were loaned to you by Oracle. Do not place tools inside a container that is being used to return a CMIOU.
Close the shipping container and seal it with the packaging tape supplied by Oracle.
Apply the shipping label to the shipping container.
Notify Oracle or an authorized shipper that the carton container is ready for pickup.

OBTAIN CUSTOMER ACCEPTANCE

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

1. When SP ILOM is available, verify that there is no faulty components

-> show faulty
-> show /System/Open_Problems
faultmgmtsp> fmadm faulty

2. Start the server by running the ILOM command "start /System" (requires Oracle ILOM Reset and Host Control (r) user role).
