Mounting the rear bracket
The Switch 4500G 24-Port and Switch 4500G 48-Port series do not need
rear brackets. The description on mounting rear brackets is only for the
Switch 4500G PWR 24-Port and Switch 4500G PWR 48-Port series.
Mount a screw on the back of the switch to closely connect the switch with
the rear bracket to support the switch. There are three positions for screw
mounting as shown in Figure 12.
