1 this unit should be mounted at the bottom of the rack if it is the only unit in the rack.
2 when mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.
3 if the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack. statement 1006
follow these steps to install a catalyst 4500 series switch in a rack:
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 you to move around the chassis.
b. use a 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) but not greater than 32 inches (81.3 cm).
c. measure the space between the inner edges of the left front and right front mounting posts to ensure that it is 17.75 inches (45.09 cm) wide. (the chassis is 17.25 inches [43.8 cm] wide and must fit between the mounting posts.)
d. open the rack-mount kit and check the component checklist in table 3-1 to verify that all parts are included.
some equipment racks provide a power strip along the length of one of the rear posts. if your 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 install the l brackets, which connect the chassis to the rack, as follows:
a. remove the screws from the front of the switch side-cover panels.
b. attach the left and right l brackets using the six m4 phillips pan-head screws (three screws per side) provided in the rack-mount kit.
see figure 3-1 for the catalyst 4503 switch, figure 3-2 for the catalyst 4506 switch, or figure 3-3 for the catalyst 4507r switch, or figure 3-4 for the catalyst 4510r switch.
c. attach the cable guide, if needed, using the m3 screws provided in the cable management kit. the cable guide attaches to the l bracket. attach the cable guide to the right side of the switch to prevent the cables from obscuring module leds.
see figure 3-5 for the catalyst 4503 switch, figure 3-6 for the catalyst 4506 switch, figure 3-7 for the catalyst 4507r switch, or figure 3-8 for the catalyst 4510r switch.
step 3 install the chassis in the rack as follows:
a. insert the rear of the chassis between the mounting posts.
see figure 3-9 to see how to install the catalyst 4503 switch in a rack.
see figure 3-10 to see how to install the catalyst 4506 switch in a rack.
see figure 3-11 to see how to install the catalyst 4507r switch in a rack.
see figure 3-12 to see how to install the catalyst 4510r switch in a rack.
b. align the mounting holes in the l bracket with the mounting holes in the equipment rack.
c. secure the chassis using at least six (three per side) 12-24 x 3/4-inch screws through the elongated holes in the l bracket and into the threaded holes in the mounting post.
d. use a tape measure and level to ensure that the chassis is installed straight and level.
step 4 make sure that the ejector levers are completely closed and the supervisor engine and switching modules are installed securely.
step 5 tighten any loose captive installation screws on the supervisor engine and the switching module.
step 6 connect the switch to an appropriate ground. refer to system ground connection guidelines, page 3-18. the system must have a ground connection before power is supplied to the switch.
