Installing the Fan Tray

To install the fan tray, follow this procedure (see Figure 70):

When sliding the fan tray into the chassis, take care not to catch and pinch any dangling PIC cables with the edges of the tray. Also make sure your fingers are not near the fans, which start spinning as soon as the fan tray contacts the midplane.

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. Make sure the router is attached to a proper earth ground. For more information about ESD, see Preventing Electrostatic Discharge Damage.
2. Grasp the sides of the fan tray and align the rear of the tray with the guides inside the chassis.
3. Slide the fan tray all the way into the chassis.
4. Tighten the thumbscrew at each end of the cable management system.
5. Rearrange the PIC cables in the cable management system. For more information about proper cable arrangement, see Maintaining PICs and PIC Cables.
