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:
• Attaching Brackets to the Catalyst 3550-12T and 3550-12G Switches,
page 3-10
• Attaching Brackets to the Catalyst 3550-24, 3550-24-DC, 3550-24-FX,
3550-24PWR, and 3550-48 Switches, page 3-14
• Mounting the Switch in a Rack, page 3-17
Note 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 3550-12T and 3550-12G
switches, order part number RCKMNT-3550-1.5RU=. For the Catalyst 3550-24,
3550-24-DC, 3550-24-FX, 3550-24PWR, and 3550-48 switches, order part
number RCKMNT-1RU=.
Attaching Brackets to the Catalyst 3550-12T and 3550-12G Switches
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 700-11523-01; for 24-inch racks, use bracket part number
700-12398-01. Figure 3-1 through Figure 3-6 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.
