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.

Solution

DISPATCH INSTRUCTIONS

WHAT SKILLS ARE REQUIRED?: No special skills required, Customer Replaceable Unit (CRU) procedure

TASK COMPLEXITY: 0

TIME ESTIMATE: 15 minutes

HOT replacement

REMOVAL/REPLACEMENT INSTRUCTIONS:

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? : N/A

WHAT ACTIONS ARE REQUIRED?:

Removing a Power Cord

Caution

Do not remove more than one power cord at a time, to avoid affecting system performance.
You can only remove a power cord with the server running if you have a single power cord that is faulty and if you have a replacement power cord.

1. Document which chassis (CMIOU chassis or Switch Chassis) and which exact AC input socket you are going to disconnect the power cord from.

2. Document which PDU (Right or Left) and which exact PDU AC output socket you are going to disconnect the power cord from.

3. Disconnect the power cord from the PDU socket.

4. Disconnect the power cord from the Chassis socket.

5. Remove the power cord.

Installing a Power cord

1. Connect the power cord to the singe free Chassis AC input socket.

2 Connect the power cord to the single free PDU AC output socket

WHAT ACTIONS ARE NEEDED TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

1. Verify that the fault has been cleared and the replaced component is operational

2. Verify that the Power OK LED is lit, and that the Fault LED and front and rear Service Required LEDs are not lit.

3. Verify that there is no faulty components

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

4. Perform one of the following tasks based on your verification results

If the previous steps did not clear the fault, refer to doc 1309092.1 for information about the tools and methods you can use to diagnose and clear component faults.
If the previous steps indicate that no faults have been detected, the component has been replaced successfully. No further action is required
