Chapter 3 Installing the Cisco XR 12410 Router

Rack-Mounting the Router Chassis

In a center-mounted position, an optional set of center-mount brackets are secured to the rack posts and the chassis rack-mounting flanges are then secured to the center-mount brackets. The center-mountedposition moves the center of gravity of the chassis closer to the vertical axis of the rack posts, which adds to the security and stability of the rack installation.

Verifying Rack Dimensions

Before you install the chassis, measure the space between the vertical mounting flanges (rails) on your equipment rack to verify that the rack conforms to the measurements shown in Figure 3-12.

Step 1 Mark and measure the distance between two holes on the left and right mounting rails.

The distance should measure 18.31 inches ± 0.06 inches (46.5 cm ± 0.15 cm).

Note Measure for pairs of holes near the bottom, middle and top of the equipment rack to ensure that the rack posts are parallel.

Step 2 Measure the space between the inner edges of the left front and right front mounting flanges on the equipment rack.

The space must be at least 17.7 inches (45 cm) to accommodate the chassis which is 17.25 inches (43.8 cm) wide and fits between the mounting posts on the rack.
