To replace the disk drive bay fans:
1. Disconnect the fan power cable from the power supply connector.
2. Note the cable position and airflow direction of the old fan. Pull up on the metal tab
attached to the fan until it clears the chassis, carefully guiding the wires and connectors on
the fan out of the cable access hole at the bottom of the fan cage. Note the routing of the
wires and connectors on the old fan, as the new fan cables and connectors should be
routed the same way. See the following figure.
