Power specifications
WARNING! Disconnect both power cables to remove all power from the 4/256 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 listed in Table 50 are calculated for fully loaded systems with four power
supplies. A fully loaded system has eight FC4-32 port blades, two CP4 cards, and three blower
assemblies.
NOTE: HP ships two power supplies standard. Users can purchase optional Director power
supplies for the remaining two slots as required.
