Installing a DC Power Supply
Caution Do not attempt to remove the fan cables without first depressing the tab as shown in Figure 6-27. You
can damage the fan cables by applying stress if the connector is not removed properly.
Step 4 Disconnect the fan cable as shown in Figure 6-27, and set the fan aside.

Step 5
Remove the next fan and disconnect its cable.
Step 6 Remove the cables for the two remaining fans. Remove the last two fans.
Step 7 Replace the fans, starting with the fan farthest away from the power supply. If the bezel is removed, make
sure the fan farthest away from the power supply does not cover the bezel holes.
Note Make sure that the label on the fan faces the chassis wall to ensure proper airflow direction.
Step 8 Install cable clamps onto the fans by aligning cable clamp holes over fan mounting holes and pressing
rivets through both. (See Figure 6-28.)
