HP DC SAN Backbone Director Switch Hardware Reference Guide (5697-2158, August 2012)

DC SAN Director
The power subsystem is a redundant +48 VDC power distribution system with a provision for up
to four 1,000 W, 48 VDC bulk power supplies. Four bulk power supplies produce the intermediate
distribution voltage in the distributed power system.
The power specifications in Table 25 (page 103) 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 blower assemblies.
Table 25 DC SAN Director power specifications
ValueSpecification
A fully loaded switch requires a maximum of 750 VA. This results in a main
current of 3.2 A at 240 VAC line voltage or 3.6 A at 208 VAC line voltage.
The rated AC input range is 180 to 264 VAC or 110 to 120 VAC.

The supply outputs remain within specified regulation for a minimum of 20
msec after the AC mains are disconnected.
Ride through
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.

Power cords
The power cords provided with the DC SAN Director are specific to the country where it is installed.
For each of these types of power cords (see Table 26 (page 103)), the end that connects to the
Director chassis has an IEC 60320/C19 cable connector. The two AC power receptacles on each
chassis are equipped with IEC 60320/C20 power connectors.
Contact HP to order a power cord.
CAUTION: Never use the power cord supplied with your DC SAN Director for other products.
