Removing and Installing the Cisco AS5300 Power Supply
Step 7 Disconnect the fan cable. (See Figure 7.)
Caution Do not attempt to remove the fan cables without first depressing the tab as shown in Figure 7. You can
damage the fan cables by applying stress if the connector is not removed properly.

Step 8
Remove the next fan and disconnect its cable. You can disconnect the cables for the two remaining fans
without removing the fans.
Note There are three different lengths of 2 wire +/- 12 VDC power cables. The two shortest cables go
to the two fans that were removed in Step 6 through Step 8. The two longer cables go to the two
remaining fans. The single medium-length cable goes to the power connector on the backplane.
If you use an incorrect cable to connect a fan or the backplane, then you are unable to make one
of the other connections.
