II. Replacing the fan tray
Step 1: Wear the ESD-preventive wrist strap. Screw off the captive screws on both
sides of the fan tray. Pull the fan tray outward with one hand contacting the switch top
and the other hand around the handle of the fan tray to separate the fan tray positioning
pin from the backplane.
Caution:
When you replace the fan tray of an operating switch, pull the fan tray out from the
chassis only after the fans stop rotating. In this case, there is still the possibility that
fans are still rotating. Therefore do not put your hand into the fan tray to avoid bodily
injury.
Step 2: Gently pull the fan tray out of the slot along the guides.
Step 3: Put the removed fan tray into the packing bag.
Step 4: Hold the handle of the fan tray with one hand and its bottom with the other and
pull them outward. Align the fan tray with the guides in the chassis and slide it gently
into the slot until its positioning pin touches the positioning hole in the chassis.
Step 5: Screw on the captive screws on both sides of the fan tray.
