Cisco Systems Cisco 12008 manual Installing the Mounting Brackets

Installing the Mounting Brackets

You can install a single Cisco 12008 at any height in the rack, or you can “stack” as many as three routers in the rack to make maximum use of available rack space. Each installed router requires 25 inches of rack space (63.5 cm). The height of each router is 24.85 inches (63.1 cm), leaving a minimum of tolerance between each rack-mounted router.

In all cases, you should consider current and future equipment needs in determining the appropriate height for installing your router, while at the same time attempting to maintain as low a center of gravity as possible for all rack-mounted equipment.

If you choose not to install the mounting brackets, proceed to the following section entitled “Removing Components from the Router.”

To install the mounting brackets (see Figure 3-1), perform the following steps:

Step 1 Determine the proper height to install the mounting brackets in the rack.

To promote rack stability and a low center of gravity once the router is installed, attach the mounting brackets at the minimum practical height suitable to your equipment and cabling requirements.

Step 2 Position a mounting bracket on one of the posts at the desired level.

The mounting bracket is designed in a way that enables one of the lowest three holes in the bracket to match a hole in the mounting posts of the rack; the same is true for the highest three holes in the mounting bracket. Thus, you can secure the mounting bracket to the mounting post in the rack with two screws.

Step 3 Secure the bracket to the post using two screws provided in the accessory kit.

Step 4 Repeat Step 2 and Step 3 to secure a second mounting bracket on the opposite post, making sure that both brackets are installed at the same height.

Note If you intend to mount the router in a 4-post equipment rack, you have the option to install four mounting brackets on the posts. In this case, you can follow the general procedure outlined above to install the two additional mounting brackets.
