Installing The Ears On The Chassis - Cisco 7000 Series Hardware Installation And Maintenance Manual

Installing the Ears on the Chassis

The chassis should be unpacked, and you should have already verified the router configuration.
Each chassis ear has two studs that fit into holes in the chassis. The chassis has two pairs of holes on
each side: one pair near the interface processor end and one pair near the noninterface processor end.
Both ears must be installed at the same end on each side. Install the ears near the end of the router
that will be in the front of the rack. For example, if you plan to install the chassis with the interface
processor end of the router at the front and the noninterface processor end in the back of the rack,
install the ears near the interface processor end of the chassis. (See Figure 3-2.)

Installing the Ears on the Chassis
After attaching the chassis ears, we recommend that two people install the chassis in the
On the rack, measure the space between the inner sides of the left and right front posts or
mounting strips to ensure that it is at least 17.72 inches wide. (The chassis is 17.65 inches
wide with the ears installed and must fit between the mounting strips.)
Refer to Figure 3-2 and locate the guides in the chassis sides.
While referring to Figure 3-2, turn the chassis so that the end that will be in the front of the
rack is facing toward you. For example, Figure 3-2 shows the correct orientation for the
router if the noninterface processor end will face out the front of the rack.
On the sides of the chassis, locate the stud holes and tapped holes nearest you.
Attach the first chassis ear to the right side of the chassis. Hold the ear in the orientation
shown by the right ear in the Figure 3-2; the studs point toward the chassis and the
mounting holes face you.
Insert the studs into the holes on the side of the chassis, as shown in Figure 3-2.
