Precautions for FANU replacement

Caution - Before you handle any components, be sure to 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 cooling fan of the SPARC M12 has a redundant configuration so that the
system will continue to run even if one cooling fan of a FANU fails. However,
avoid running the system for a long time with a cooling fan failed. Replace the
FANU with the failed fan.

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

Do not forcibly push the FANU when mounting it in the FANBP. When mounting
the FANU, push it at two points at the bottom of its front side. Pushing any points
other than the specified ones when mounting the FANU may damage the FANU
or FANBP.

Note - You can remove a FANU in the active state.

Releasing the FANU

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: FAN (Fan Unit).

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

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

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

Removing a FANU
1. Remove the front cover.

Note - The serial number of the server main unit is printed on a label affixed on the front
cover. Store this cover such that it is not mixed up with the front covers of other SPARC M12
units.

2. Pull up the removal lever of the FANU.
Pull up the removal lever of the FANU by pressing its leaf spring.

3. Remove the FANU.
Hold the removal lever of the fan, and pull out the FANU from the FANBP.

Installing a FANU

1. Insert the FANU into the FANBP.
Insert the FANU into the FANBP, with the FANU removal lever pushed up, and connect the FANU to the FANBP connector.

Note - To connect a FANU to the FANBP, push the FANU at two places at the bottom of the
front side. Pushing the meshed section of the FANU may cause contact
with the cooling fans inside, resulting in the FANU malfunctioning.

2. Secure the FANU.
Insert the FANU into the FANBP, and fold back the FANU removal lever to secure the FANU.

3. Incorporate the FANU into the system.
If you have performed maintenance on a FANU when the server main unit is in the hot state, incorporate the FANU into the system.

4. Install the front cover.

Incorporating the FANU

1. Incorporate the FANU into the system.
After mounting the replacement FANU, return to the operation screen of the replacefru command and enter "f".
2. Check the result of incorporating the FANU.
Check that Normal is displayed under Status. Then, enter "f" to finish the maintenance of the FANU.

If the displayed status is abnormal (Degrade or Fault), finish the maintenance of
the FANU and return to the maintenance start screen. Perform maintenance on
the FANU again, and check whether the FANU 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 FRU Status After Maintenance
