I/O Subsystem Fan

Removal
1. Press the green Start Service button on the UEPO switch.
2. Locate the fan to be replaced.
3. Turn off the power as described in "Powering Off and Powering On the System" on page 825.
4. Remove the DASD cage from the front of the fan to be removed (see "I/O Subsystem DASD 4-Pack"
on page 977).
5. Slide the black retention latch on the fan assembly upward and, with the handle located on the fan,
pull the fan from the front of the I/O subsystem. A door automatically closes when the fan is removed,
preventing loss of airflow while the fan is out of the enclosure.
Replacement
Note: All four openings to the front of the fans must be covered either by a DASD 4-pack or by a DASD
4-pack filler.
Replace in reverse order. When you have completed the replacement of the DASD fan, turn on the power
as described in "Powering Off and Powering On the System" on page 825, and press the white Service
Complete button on the UEPO switch. This completes the replacement.
