DC SAN Director
The power subsystem is a redundant +48V DC power distribution system with a provision for up to
four 1000-watt, 48V DC bulk power supplies. Four bulk power supplies produce the intermediate
distribution voltage in the distributed power system.
The power specifications in
Table 47
are calculated for fully loaded systems with four power supplies.
A fully loaded system has eight FC8-48 port blades, two CP8 blades, two CR8 blades, and three

Specification
A fully loaded switch requires a maximum of 750 Volt-Amps This results in
a main current of 3.2 amps at 240V AC line voltage or 3.6 amps at 208V
AC line voltage. The rated AC input range is 180 to 264V AC or 110 to
120 VAC.

The DC SAN Director power supply self-protects from any input voltage,
static or dynamic, from zero volts to its operating ranges. It recovers to
normal operation upon returning to its operating range.
Under voltage protection
DC04 SAN Director
The power subsystem is a redundant +48V DC power distribution system with a provision for up to
two 2000-watt, 48V DC bulk power supplies. Two bulk power supplies produce the intermediate
distribution voltage in the distributed power system.
