Installing an M320 Front Fan Tray

To install a front fan tray (see Figure 1):

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis. For more information about ESD, see Preventing Electrostatic Discharge Damage to an M Series, MX Series, or T Series Router.
2. Grasp the fan tray by its handles and insert it straight into the chassis.
3. Tighten the captive screws on each side of the fan tray faceplate to secure it in the chassis.
4. If you are installing the lower fan tray, follow these steps:
   1. Unlock the cable management system and lower it to the fully lowered position.
   2. Rearrange the PIC cables in the cable management system. For more information about proper cable arrangement, see Maintaining M320 PICs and PIC Cables.
