Goal

How to Replace an Exadata Compute/Storage Node Power Supply Unit (Doc ID 1997443.1)

Solution

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED: General Sun X64 Servers Knowledge.

TASK COMPLEXITY: 0

TIME ESTIMATE: 30 minutes

FIELD ENGINEER INSTRUCTIONS:

- PROBLEM OVERVIEW: Power Supply Replacement

- WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?:

If the server has a redundant power supply, you are able to remove or install the power supply without shutting down the server, provided that the other power supply is online and working.
If the server does not have a redundant power supply unit, the server must be offline.
If a power supply unit fails and you do not have a replacement available, to ensure proper airflow, either leave the failed power supply unit installed in the server or remove the failed power supply unit and install a filler panel.

- WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1. Attach an antistatic wrist strap

2. Identify which power supply unit (0, 1, 2 or 3) requires replacement

3. Disconnect the power cord from the faulty power supply unit

4. Grasp the green power supply unit handle and press the release latch

5. Pull the power supply unit out of the node chassis

6. Install the replacement power supply by reversing this procedure

Caution – Whenever you remove a power supply unit, you should replace it with another power supply unit or a filler panel. Otherwise, the server might overheat due to improper airflow.

OBTAIN CUSTOMER ACCEPTANCE

- WHAT ACTION DOES THE FIELD ENGINEER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

If the platform supports iLOM fault management architecture, verify the fault is cleared when inserting the new power supply using the commands:

Otherwise, no further action is required
