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.
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, page 3-19
2?attaching brackets to the catalyst 3750g-24ts switch, page 3-20
3 attaching brackets to the catalyst 3750-24ts, 3750g-24t, 3750g-12s, and 3750-48ts switches, page 3-25
4?mounting the switch in a rack, page 3-28
5?attaching the cable guide, page 3-30
installing the switch in a 24-inch rack requires an optional bracket kit not included with the switch. you can order a kit containing the 24-inch rack-mounting brackets and hardware from cisco. for the catalyst 3750g-24ts switches, order part number rckmnt-3550-1.5ru=. for the catalyst 3750-24ts, 3750g-24t, 3750g-12s, and 3750-48ts switches, order part number 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 3-10 and figure 3-11 show how to remove the chassis screws in a one-rack-unit (ru) switch.

attaching brackets to the catalyst 3750g-24ts 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 part number 700-11523-xx; for 24-inch racks, use part number 700-12398-xx.
figure 3-13 through figure 3-18 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.

the bracket orientation and the brackets 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-xx; for 24-inch racks, use bracket part number 700-13248-xx. figure 3-19 through figure 3-25 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 3-26 and figure 3-27.
after the switch is mounted in the rack, you might need to perform these tasks to complete the installation, run the setup program, and access the switch:
1?(optional) connect the switches in the stacks. see the "connecting stackwise cable to stackwise ports?section on page 3-37.
2?connect to the console port, and start the emulation software. see the "connecting to the console port"?section on page 1-4 and the "starting the terminal emulation software"?section on page 1-6.
3?power on the switch. see the "connecting to a power source"?section on page 1-6. if the switches are stacked, see the “powering considerations” section on page 3-13.
4?run the setup program. see the "completing the setup" program?section on page d-11.
5?connect to the front-panel ports. see the "connecting to the 10/100 and 10/100/1000 ports"?section on page 3-44 and the "connecting to an sfp module"?section on page 3-46 to complete the installation.
to use the cli, enter commands at the switch] prompt through the console port by using a terminal program or through the network by using telnet. for configuration information, refer to the switch software configuration guide or the switch command reference. to use cms, go to the “accessing the switch from your browser” section on page 1-13.
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, as shown in figure 3-28 and figure 3-29 to attach the cable guide to the left or right bracket.
the catalyst 3750-48 switch ships with a special cable guide, as shown in figure 3-29. this cable guide secures up to 48 cables. use the supplied black screw to mount it on the left bracket.
