General Tabletop or Workbench Installation Chapter 3 Installing a Cisco 7200 VXR Router 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 Step 2 Step 3 Step 4 Step 5 Step 6 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. 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. 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. 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. 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. 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. 3-14 Cisco 7200 VXR Installation and Configuration Guide OL-5013-09
