Chapter 9: Maintaining E-series Routers
Removing the Fan Tray
To remove the fan tray:
1. (ERX-14xx models only) Place a flathead screwdriver in the groove where the
top bezel meets the chassis on the top of the system, and lever the top bezel off
the front of the system.
2. With an appropriate screwdriver, loosen the captive screws located at the
corners of the fan tray.
3. Pull the fan tray halfway out of the shelf.
4. Pull the tray out of the chassis.
Installing the Fan Tray
To install the fan tray:
1. 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.
2. 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.
3. Push the fan tray toward the back of the shelf until it stops.
There is an electrical connector on the back of the fan tray that pairs with an
electrical connector at the back of the shelf.
4. 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.
5. (ERX-14xx model only) Push the top bezel back on the front of the system.
WARNING: Do not place your fingers near the fans when removing the fan tray. The
blades may still be moving.
WARNING: Slowly slide the fan tray out of the chassis. The tray does not have stops
to prevent it from sliding all the way out.
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.
