Space Clearance:
The S9701-82DC chassis width is 17.16 inches (43.6cm) and is shipped with
an adjustable mounting rail kit suited for standard 19 inch (48.3cm) wide racks. The depth of
the S9701-82DC chassis is 24 inches (60.9cm) without the field replaceable units (FRUs). The
fan FRU handle will extend outwards by 1.2 inches (2.9cm) and the power supply handles will
extend outwards by 1.1 inches (2.7cm). Therefore, to accommodate the fan handles, power
supply handles, airflow and cabling, a minimum space clearance of 6 inches (15.2cm) is
needed at front and back of the S9701-82DC. A total minimum reserve depth of 36 inches
(91.4cm) is required.
