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

Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well
grounded.
2.
Unpack the fan tray and check that the fan tray model is correct.
3.
Grasp the handle of the fan tray with one hand and support the fan tray bottom with the other, and
slide the fan tray along the guide rails into the slot until the fan tray seats in the slot and has a firm
contact with the backplane (see callout 1 in

).
4.
Fasten the captive screw on the fan tray with a Philips screwdriver until the fan tray is securely
attached in the chassis (see callout 2 in
