Chapter 3 Installing the Cisco 7206
General Tabletop or Workbench Installation
This completes the procedure for installing the rack-mount brackets and cable-management brackets on
the Cisco 7206. Proceed to the following section, “
Installing the Chassis in the Rack .”
Installing the Chassis in the Rack
After installing the brackets on the chassis, mount the router by securing the rack-mount brackets to two
posts or mounting strips in the rack using the six slotted screws provided. Because the brackets support
the weight of the entire chassis, be sure to use all six slotted screws to fasten the two rack-mount brackets
to the rack posts.
Figure 3-2 , Figure 3-3 , Figure 3-4 , and Figure 3-5 show typical installations in
19-inch, four-post and telco-type equipment racks.
We recommend that you allow at least 1 or 2 inches (2.54 or 5.08 cm) of vertical clearance between the
router and any equipment directly above and below it.
To install the chassis in the rack, complete the following steps:
Step 1 On the chassis, ensure that all captive screws on the network processing engine, the I/O controller, and
each power supply are tightened and the port adapter levers are in the locked position.
Step 2
Make sure that your path to the rack is unobstructed. If the rack is on wheels, ensure that the brakes are
engaged or that the rack is otherwise stabilized.
Note
Two people should perform Step 3 through Step 6.
Step 3
Position the chassis so that the front end is closest to you. Lift the chassis and move it to the rack. To
prevent injury, avoid sudden twists or moves.
Step 4 Slide the chassis into the rack, pushing it back until the brackets (installed at the front or rear of the
chassis) meet the mounting strips or posts on both sides of the equipment rack.
Step 5
While keeping the brackets flush against the posts or mounting strips, position the router so the holes in
the brackets are aligned with those in the mounting strips.
Step 6 Insert all six 10-32 x 3/8 slotted screws (three on each side) through the brackets and into the mounting
strip (use the top and bottom bracket holes, as shown in
Figure 3-2 , Figure 3-3 , Figure 3-4 , and
Figure 3-5 ). Using a 1/4-inch, flat-blade screwdriver, tighten all the screws.
This completes the procedure for installing the chassis in the rack. Proceed to the “Connecting Port
Adapter Cables” section on page 3-14 to continue the installation.
General Tabletop or Workbench Installation
The router should already be in the area where you will install it, and your installation location should
already be determined. If not, refer to the
“Site Requirements” section on page 2-2 in Chapter 2,
“Preparing for Installation.”
When installing the Cisco 7206 on a workbench or tabletop, ensure that the surface is clean and in a safe
location and that you have considered the following:
• The router requires at least 3 inches (7.62 cm) of clearance at the inlet and exhaust vents (the right
and left sides of the router).
