WARNING:
If the chassis is powered on, once the fan tray’s connector is seated in
the backplane’s connector, the fan blades start spinning. Proper care
should be taken to prevent contact with the spinning fan blades.
2. Pressing on the front of the fan tray bracket, push the fan tray half way in and
attach the ground wire. Then, fully seat the fan tray.
NOTE:
When the fan tray is running at full speed the Fan ALARM LED will go
out, indicating that all fans are operating properly.
3. Loosen the two screws slightly on each locking bracket and slide the locking
brackets outward until they engage the slots located on the left and right side
plates.
NOTE:
When properly extended or locked, the brackets should be extended into
the slots on the side plates and a threaded insert on the locking bracket
should be aligned with (and visible through) the two outermost holes of
the fan tray.
4. Tighten the two screws on each bracket, making sure that the bracket’s
inserts stay aligned with the holes in the fan tray.
