The Switch 4500G 24-Port and Switch 4500G 48-Port units 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. 

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.
