Chapter 3: Installing the Chassis in an Equipment Rack
84
Adjusting the Equipment Rack Brackets
You may change the positions of the two pre-installed equipment rack
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
chassis so that the rear panel is flush with the front of the equipment rack.
The different bracket positions are listed in Table 24 and illustrated in
Figure 38 on page 85 and Figure 39 on page 85. 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 38.
The dimension (X) between the front panel and the rack rails is
given for each rack mounting bracket position in Table 24.
