Installing a Fan Tray
Caution If you are replacing a fan tray during operations, you must insert the new fan tray within 2 minutes of
removing the original fan tray.
To install a fan tray, follow these steps:
Step 1 Hold the fan tray with the sheet metal flange holding the connector on the bottom.
Step 2 Place the fan tray into the front chassis cavity so it rests on the chassis, and then push the fan tray into
the chassis as far as it can go until the captive screw makes contact with the chassis.
Step 3 Tighten the captive screw.
Step 4 Listen for the fans if the device is powered on. You should immediately hear them operating. If you do
not hear them, ensure that the fan tray is inserted completely in the chassis and the faceplate is flush with
the outside surface of the chassis.
Step 5 Verify that the LED is green. If the LED is not green, one or more fans are faulty. If this problem occurs,
contact your customer service representative for a replacement part.
