1.2.4 Power requirements
All Power 595 configurations are designed with a fully redundant power system. To take full
advantage of the power subsystem redundancy and reliability features, each of the two power
cords should be connected to different distribution panels.
Table 1-7 lists the electrical and thermal characteristics for the Power 595 server.

Table 1-8 on page 8 lists the electrical characteristics for 4.2 GHz and 5.0 GHz Power 595
servers, and the Powered Expansion Rack (U.S., Canada, and Japan).
