Telco Rack
Figure 2-2c shows a telco-type rack. The telco-type rack is an open frame consisting of two posts tied together by a cross-bar at the top and a floor stand at the bottom.
This type of rack is usually secured to the floor and sometimes to an overhead structure or wall for additional stability. The router chassis can be installed in the telco-type rack either in a front-mounted position or a center-mounted position.
In the front-mounted position, you secure the chassis rack-mounting brackets directly to the rack posts (Figure 2-3).
