Precautions for PSU replacement

Caution - Before you handle any components, be sure wear a wrist strap to ground any static
electricity. If you perform this procedure without a wrist strap, individual components or the
overall system may be seriously damaged

The power control of the SPARC M12 has a redundant configuration so that the
system will continue to run even if one PSU fails. However, avoid running the
system for a long time in a faulty condition. Replace the failed PSU.

When there are multiple PSUs to replace, replace them one by one. If redundancy
of the PSUs cannot be secured, system-stopped replacement must be performed.

When mounting a PSU in the BPU, make sure that the PSU is oriented so that its
power connector is on the left side. Mounting a PSU in the wrong orientation may
damage the BPU or PSUBP.

Releasing the PSU

1. Log in to the XSCF shell.

2. Execute the replacefru command to display the maintenance menu.

XSCF> replacefru

3. With a number key, select the chassis requiring maintenance.

4. With a number key, select the CRU requiring maintenance.

Example: PSU (Power Supply Unit).

5. With a number key, select the faulty CRU.
Example: /BB#x/PSU#x.

6. Confirm that the selected CRU is displayed, and then enter "r".

7. Remove the PSU to be replaced, as instructed in the onscreen message.
Do not enter "f" until you mount the replacement PSU.

Removing a PSU

1. Remove the power cord.
Remove the power cord from the cable clamp of the PSU requiring maintenance and then remove the power cord from the PSU.

2. Pull down the handle of the PSU.

3. Remove the PSU from the server main unit.

Note - For your safety, remove the power cord from the PSU before removing the PSU from
the server main unit.

Installing a PSU

1. Install a PSU to the server main unit.
Insert the PSU into the server main unit, push it until its latch locks, and then push up the handle of the PSU.

Note - When inserting the PSU into the server main unit, make sure that the PSU power
outlet is on the left side.

2. Install the power cord to the PSU.
Connect the power cord to the PSU and then secure the cord with the cable clamp.

Incorporating the PSU

1. Mount the replacement PSU, and connect the power cord to it. After connecting the power cord, wait for at least 10 seconds.

2. Check the result of incorporating the PSU.

Check that Normal is displayed under Status. Then, enter "f" to finish the maintenance of the PSU.

Note -If the displayed status is abnormal (Degrade or Fault), finish the maintenance of
the PSU and return to the maintenance start screen. Perform maintenance on the
PSU again, and check whether the PSU is correctly mounted.

3. End the replacefru command.
When the maintenance start screen appears, enter "c" to end the replacefru command.

- WHAT ACTIONS ARE REQUIRED TO RETURN THE SYSTEM TO AN OPERATIONAL STATE?:

Check the PSU status after maintenance

XSCF> showstatus
