3.3.1 Installing a fan tray

Select appropriate fan trays as needed. For the optional power modules and their
specifications, see "Hot swappable fan trays".
CAUTION:
To prevent damage to the fan tray or the connectors on the backplane, insert the fan tray gently. If you
encounter a hard resistance while inserting the fan tray, pull out the fan tray and insert it again.
To install a fan tray:
1) 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 Figure 3-15).
4) Fasten the captive screw on the fan tray with a Philips screwdriver until the fan tray is
securely attached in the chassis (see Figure 3-15).If the captive screw cannot be
tightly fastened, check the installation of the fan tray.
