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.

Figure 2-14through Figure 2-19show 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.
