to install the switch in a 19-inch or 24-inch rack (24-inch racks require optional mounting hardware), follow the instructions described in these procedures:
1 removing screws from the switch.
2 attaching brackets to the catalyst 3560 switch.
3 mounting the switch in a rack.
4 attaching the cable guide.
to prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. the following guidelines are provided to ensure your safety:
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
installing the switch in a 24-inch rack requires an optional bracket kit that is not included with the switch. you can order a kit containing the 24-inch rack-mounting brackets and hardware from cisco. the kit part number is rckmnt-1ru=.
removing screws from the switch
if you plan to install the switch in a rack, you must first remove screws in the switch chassis so that mounting brackets can be attached. figure 2-1 shows how to remove the chassis screws in a catalyst 3560 switch.

attaching brackets to the catalyst 3560 switch
the bracket orientation and the brackets that you use depend on whether you are attaching the brackets for a 19-inch or a 24-inch rack. for 19-inch racks, use bracket part number 700-8209-01; for 24-inch racks, use bracket part number 700-13248-01. figure 2-2 through figure 2-7 show how to attach each type bracket to one side of the switch. follow the same steps to attach the second bracket to the opposite side.

mounting the switch in a rack
after the brackets are attached to the switch, use the four supplied number-12 phillips machine screws to securely attach the brackets to the rack, as shown in figure 2-8.

after the switch is mounted in the rack, you need to do these tasks to complete the installation:
1 power on the switch. see the “verifying switch operation” .
2 connect to a 10/100 or 10/100/1000 port and run express setup. see the catalyst 3560 switch getting started guide for instructions.
3 connect to the front-panel ports. see the “connecting to the 10/100 or 10/100/1000 ports” and the “connecting to sfp modules” section to complete the installation.
for configuration instructions about using the cli setup program, go to appendix c, “configuring the switch with the cli-based setup program.”
attaching the cable guide
we recommend attaching the cable guide to prevent the cables from obscuring the front panel of the switch and the other devices installed in the rack. use the supplied black screw shown in figure 2-9 to attach the cable guide to the left or right bracket.
