Space Clearance:
The S9705-48D 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
S9705-48D chassis is 30 inches (76.2cm) without the field replaceable units (FRUs). The handle
of fan FRU is 1 inch (2.5cm) and the handle of the PSU FRU is 1.5 inches (3.8cm). Therefore, to
accommodate the fan, power supply handles, airflow and cabling, a minimum space
clearance of 6 inches (15.2cm) is needed at front and back of the S9705-48D. A total
minimum reserve depth of 42 inches (106.6cm) is required.
