CHAPTER 4 SERVICE PROCEDURE
b. TO REPLACE THE FRONT FAN
1. Position the fan on the board guide.
An arrow on the side of the fan indicates the airflow direction. Make sure the fan is posi-
tioned so that the arrow points inside the iR-M2 and the fan cable can reach
motherboard connector FAN3.
2. Install the fan on the board guide using the two screws (and washers, if present) you re-
moved earlier.
3. Hook the board guide (with front fan attached) into the chassis.
4. Attach the board guide to the chassis using the two screws you removed earlier.
5. Connect the fan cable to motherboard connector FAN3.
6. Replace the front panel (see page 4-8).
7. Reassemble the iR-M2 (see page 4-13) and verify its functionality (see the connection
verification steps described on page 4-15).
