Chapter 3: Installing the Chassis in an Equipment Rack
80
Adjusting the Equipment Rack Brackets
The chassis has two pre-installed equipment rack brackets. You may
adjust the brackets so that the front of the chassis is flush with, extends
beyond, or is recessed behind the front of the equipment rack. You may
also install the brackets so that the rear panel of the chassis is flush with
the front of the equipment rack.
You adjust the brackets by removing them and re-installing them in
different positions on the sides of the chassis. The bracket positions are
listed in Table 20 and illustrated in Figure 35 on page 81 and Figure 36 on
page 81. Please review the following information before moving the
brackets:
Position A, the default position, positions the chassis so that the
front of the unit is flush with the front of the equipment rack.
Position B recesses the front of the chassis by 27.39 mm (1.1 in).
Positions C to E extend the front of the chassis beyond the front of
the rack from 27.39 mm (1.1 in) to 140.85 mm (5.545 in).
Position F installs the chassis with the rear panel flush with the
front of the equipment rack.
To install the rack mount brackets in position “E,” you have to
remove the two chassis screws from the bottom-middle section of
the chassis and re-install them in front where the rack mount
bracket screws were originally, as shown in Figure 35 on page 81.
The dimension (X) between the front panel and the rack rails is
given for each rack mounting bracket position in Table 20.
