Rack-Mounting the Chassis

•Install and use the cable management brackets included with the router to keep cables organized and out of the way. Consider the equipment and cabling that is already installed in the rack. Ensure that cables from other equipment will not impair access to the interface processors, or require you to disconnect cables unnecessarily to perform equipment maintenance or upgrades.

•If you plan to use an equipment shelf, ensure that the shelf is constructed to support the weight and dimensions of the chassis. Figure 2 shows the chassis footprint, which you will need if you are designing a customized shelf.

•If you use Telco-type racks, be sure that the rack is bolted to the ﬂoor and secured. One end of the chassis mounts to the two rack posts with the chassis ears, and the rest of the chassis is cantilevered off of the posts. Ensure that the weight of the chassis does not make the rack unstable. Some Telco-type racks are also secured to ceiling brackets, if warranted by the weight of the equipment in the rack.

To mount the chassis in a rack, you will attach two ears to the sides of the chassis, then mount the ears to the rack-mounting strips or posts. The chassis is cantilevered off the ears. The chassis ears attach to either the front or back of the chassis, so that you can position either the interface processor or noninterface processor end at the front of the rack. In a four-post equipment rack with mounting strips in the rear posts, you can also mount the ears to the two rear posts; however, ﬁrst ensure that the rear posts are free of obstacles such as structural supports or a power strip.

Figure 3 shows a typical 19-inch equipment rack with a power strip along one of the back posts.

Note For this procedure, the Cisco 7010 and Cisco 7505 chassis are functionally the same.

If your rack has this feature, mount the interface processor end of the router away from the power strip to avoid problems accessing processor modules and cables. Also, if you will install the cable management brackets, ensure that the power strip will not block the sides of the brackets and prevent you from routing the cables through them. Install the cable management brackets after you install the chassis in the rack.
