Figure 3. Minimum Area Dimensions When the Chassis has DC Power
Supplies
The minimum space on the back panel of the chassis can be reduced to
15 cm (6 in.) when the device has DC power supplies because the power
wires are connected to the front panel of the power supplies. However, the
minimum space on the front panel must remain at 51 cm (20 in.) to allow
for the installation of the line cards and power supplies.
Wallboard
Requirements
Please observe the following guidelines if you are installing the chassis on
wallboard:
 The brackets are designed for wood studs at 16” intervals.
 You should use a stud finder to locate and mark the middle of the
studs and to identify the locations of metal conduits and any hot
AC wiring in the reserved wall area.
 All four bracket screws should be fastened to studs in the
wallboard. Refer to Figure 4 on page 17.
