Two-Sided Chassis
The two-sided chassis have 12 holes on each side, as shown in Figure 3-4. These holes
facilitate mounting in a 19- or 23-inch rack (48.2 or 58.4 cm). You can attach the front, middle,
or rear of this chassis to a rack, using the mounting brackets as previously shown for the
front-loading chassis with power supplies on the side. To place a two-sided chassis on a
tabletop, attach the mounting brackets to the two holes on the bottoms of the chassis sides.
Figure 3-4. Two-Sided Chassis Mounting Holes
Be sure both the front and rear of the chassis are accessible for inserting and removing cards.
The voice, data, and WAN cards, and the power cables, are attached to connectors at the rear
of the chassis. Table 3-1 lists the minimum clearances required between the system chassis and
the nearest objects.
