Installation Environment Requirements

• Power Reserve: The S9705-48D power supply is available with:
1. DC Version: 1+1 Redundant and hot swappable, active/active -48V voltage DC power supply
field replaceable unit or;
2. AC Version: 1+1 Redundant and hot swappable, active/active 200V to 240V AC power
supply field replaceable unit.
To ensure the redundant, active/active feed power design functions properly, a field with
dual power circuit is recommended with a reserve of at least 1500 watts on each power
circuit.
• 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.
• Cooling: The S9705-48D airflow direction is front-to-back. Make sure the equipment on
the same rack have the same airflow direction.
