Installing a fan tray

grounded.
2. Unpack the fan tray and verify that the fan tray model is as required.
3. Orient the fan tray with the TOP mark facing up.
4. Align the fan tray with the fan tray slot. Holding the fan tray handles, slide the fan tray into the
slot along the guide rails. Make sure the fan tray is fully seated in the slot and has a firm contact

you encounter a hard resistance while inserting the fan tray, pull out the fan tray and insert it
again.
