Chapter 3 Installing a Cisco 7200 VXR Router
General Tabletop or Workbench Installation
Installing the Chassis in the Rack
After installing the brackets on the chassis, you 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 two-post 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 services engine (NSE) or network
processing engine (NPE), 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.
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 3-19 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, see
Chapter 2, “Preparing for Installation,” the “Site Requirement
Guidelines” section on page 2-3 and the Site Preparation and Safety Guide.
When installing a Cisco 7200 VXR router 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).
• The router should be installed off the floor. (Dust that accumulates on the floor is drawn into the
interior of the router by the cooling fans. Excessive dust inside the router can cause overtemperature
conditions and component failures.)
• There must be approximately 19 inches (48.3 cm) of clearance at the front and rear of the router for
installing and replacing router field-replaceable units (FRUs), or accessing network cables or
equipment.
