Installing a Replacement Fan Tray Assembly
You will need a Phillips screwdriver to install a replacement fan tray.
Procedure
To install a replacement fan tray:
1. Hold the replacement fan tray horizontally and guide its tabs into the two card
guides located inside the right and left side plates.
WARNING:
If the chassis is powered on, when the fan tray’s connector is seated in the
backplane, 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.
