Installing the Fan Tray

To install the fan tray:

Caution: Do not use the fan tray handle to carry the fan tray assembly. Use the handle only to push the tray into the chassis.

Hold the tray horizontally (ERX-14xx models) or vertically (ERX-7xx models and ERX-310 routers) or so that the captive screws point toward you and you can read text on the labels.
Place the bottom corners of the tray housing in the plastic shelf guides of the fan tray compartment; push toward the back of the chassis halfway, and stop.
Push the fan tray toward the back of the shelf until it stops.
An electrical connector on the back of the fan tray pairs with an electrical connector at the back of the shelf.
With an appropriate screwdriver, tighten the captive screws.
Alternate between screws when tightening them to ensure that the electrical connectors at the back of the tray fit tightly.
(ERX-14xx model only) Push the top bezel back on the front of the system.
