Installing an M120 Fan Tray
To install a fan tray (see Figure 67 on page 192 and Figure 68 on page 193):
1. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
2. Grasp the fan tray by its handle and insert it straight into the chassis. Note the correct
orientation by the "this side up" label on the top surface of the fan tray.
3. Tighten the captive screws on each side of the fan tray faceplate to secure it in the
chassis.
4. Lower the cable management system back into position, if necessary.
