Removing the Existing Fan Tray Assembly
You will need a Phillips screwdriver to remove the vent cover and fan tray.
"
Procedure
To remove the existing fan tray
assembly:
1. Remove three screws from the
fan cover plate, and then remove
the cover plate from the chassis,
taking care not to damage the
LED protruding through the cover
plate.
2. Loosen (but do not remove) the
two screws on each locking
bracket, and use them to slide
both locking brackets toward
the middle of the front panel
until the ends clear the slots
in the side plates.
NOTE:
There are two cutouts in the front face of the fan tray labeled PULL AREA.
This is where you place your fingers to pull the fan tray out of the chassis.
!
WARNING:
A MECHANICAL HAZARD EXISTS DUE TO ROTATING FAN BLADES.
KEEP HANDS AND FINGERS AWAY FROM FAN BLADES DURING
REMOVAL OF FAN TRAY. USE ONLY THE DESIGNATED PULL AREAS
TO DISENGAGE THE FAN TRAY.
