Chapter 3 Installing the Switch Installing the Catalyst 2948G and 2980G Switches Rack-Mounting the Catalyst 2948G and 2980G Switches To install Catalyst 2940G and 2980G switches in a 19-inch rack, follow these steps: Step 1 Prepare for installation as follows: a. Place the chassis on the floor or on a sturdy table, as close as possible to the rack. Leave enough clearance to allow yourself to move around the chassis. b. Use the tape measure to measure the depth of the rack. Measure from the outside of the front-mounting posts to the outside of the rear-mounting strip. The depth must be at least 19.25 inches (48.9 cm) and not greater than 32 inches (81.3 cm). c. Measure the space between the inner edges of the left front- and right frontmounting posts to ensure that it is 17.75 inches (45.09 cm) wide. (The chassis is 17.5 inches [44 cm] wide and must fit between the mounting posts. See Figure 3-2.) d. Open the rack-mount kit and refer to the component checklist in Table 3-1 to verify that all parts are included. Table 3-1 Rack-Mount Kit Checklist Part Description L brackets M4 Phillips pan-head screws 12-24 x 3/4-inch Phillips binder-head screws Quantity 2 4 6 Note Some equipment racks have a power strip along the length of one of the rear posts. If the rack has this feature, consider the position of the strip when planning fastener points. Before installing the L brackets on the chassis, determine whether to install the chassis from the front or the rear of the rack. Step 2 Attach the left and right L brackets using the four M4 Phillips pan-head screws provided in the rack-mount kit (see Figure 3-1). 78-6286-05 Catalyst 2984G, 2948G-GE-TX, and 2980G Switch Hardware Installation Guide 3-7
