To add a chassis expander, follow the above steps.
You only need to leave a small space between the chassis and the
chassis expander. The air circulates from the side of the chassis. To
install the chassis expander, start at the next 5u pattern of mounting
holes (see Note

). This results in the chassis expander being

approximately 6 mm (1/4 in.) from the first chassis.

Note 1: The holes in the rack occur in sets of three, spaced at
16 mm (5/8 in.) + 16 mm (5/8 in.) + 12.5 mm (1/2 in.). Each set
of three holes is one "u" and spans 44.5 mm (1.75 in.). In a 5u
pattern, the chassis is mounted over five sets of holes.

Note 2: In addition to more chassis, you can install other Data
Communication Equipment in a rack/equipment cabinet with the
Chassis system. Refer to

"Multiple pieces of equipment in an

equipment rack/cabinet" (page 134)

for grounding instructions for

multiple pieces of equipment in a rack/equipment cabinet.
