Selecting a Wall Location
The following sections contain information on how to select a wall location
for the chassis.
Minimum
Dimensions of the
Reserved Wall
Area
This section discusses the recommended minimum dimensions of the
reserved wall area for the chassis.
Note
You might not be able to install or service the components of the
chassis if the reserved wall area is smaller than the recommended
minimum sizes given in this section.
The recommended minimum dimensions of the wall area for the unit
depend on whether the chassis has AC or DC power supplies. The
reserved wall area for a chassis that has AC power supplies has to be
larger than a chassis with DC power supplies, because AC power supplies
are powered on from the back panel of the chassis, whereas DC power
supplies are powered on from the front panel.
The minimum dimensions for the wall area for a chassis that has AC
power supplies are listed here:
 Height: 84 cm (33 in.)
 Width: 121 cm (48 in.)
The dimensions are illustrated in Figure 2 on page 15.
