SwitchBlade x3112 Installation Guide

Before installing the AT-SBx3112 Chassis, you need to determine where
the horizontal position of the chassis front panel will be relative to the
vertical rack rails. The AT-SBx3112 Chassis rack mounting brackets come
installed from the factory so that the chassis is flush with the rack rails after
installation. See position “A” in Figure 29 on page 58.
You may decide to extend (positions “B” through “E” in Figure 29 on page
58) or recess (position “F” in Figure 30 on page 59) the horizontal position
of the chassis relative to the rack mounting rails. You can do this by
removing both rack mounting rails and re-attaching them in the
appropriate holes on each side of the chassis. The dimension (X) between
the front panel and the rack rails is given in Table 16 for each rack
mounting bracket position.
