Installing the Switch in a Rack

The switch is shipped with two brackets for mounting the unit in a rack. The brackets can be attached to the chassis four ways. You can install the chassis so that it is flush with the front of the rack or so that it extends forward from the rack. Figure 12 illustrates the different ways that you can install the brackets and how much the chassis extends from the front of the rack.

ˆMethod A - Flush with front of rack

ˆMethod B - 4.5cm (1.75 in.)

ˆMethod C - 18.4 cm (7.25 in.)

ˆMethod D - 21.6 cm (8.5 in)
