Installing the Mounting Brackets
Cisco 12008 Gigabit Switch Router Installation and Configuration Guide 3-4
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.
