Checking the Installation

Perform the following steps to verify that the new blower is installed correctly.
Step 1:
Turn all power supplies back ON. The AC Power LED on all power supplies
should light. If any do not, or if the DC Fail LED is lit, the power supply has
failed. Check the power cables to ensure they are connected.
Step 2:
Listen for the blower; you should immediately hear it operating. If you do
not hear it, turn OFF the system power and do the following:
Remove the top and bottom front chassis panels (refer to "Removing and
Replacing the Front Chassis Panels" on page 6).
Check the blower power connector and ensure that it is fully seated in
the backplane port by pinching the sides and pushing it firmly into the
port.
Check the two wires between the blower and the power connector: the
red or purple +24V wire and the black ground wire. Ensure that they
have not pulled out of the power connector by pinching each wire near
the back connector and pushing it firmly into the connector.
Replace the front chassis panels, turn the power supplies back ON, and
listen for the blower.
Step 3:
If after several attempts the blower does not operate, or if you experience
trouble with the installation (for instance, if the captive blower screws do not
align with the backplane holes), contact a service representative or refer to
"Obtaining Technical Assistance" on page 2.
This completes the blower replacement.
