Current Rating, Power Plug, Receptacle, and Connector for Three-Phase (60 Hz only)

Table 5.2 lists the current rating and power plug, receptacle, and connector requirements
for three-phase 60-Hz 9960 subsystems. In a three-phase 9960 subsystem the controller
frame (DKC) receives its AC input power from the first disk array frame (DKU) via internal
cabling, so that subsystem will not require any customer outlets for the controller frame.
The user must supply all power receptacles and connectors for both 60-Hz and 50-Hz
subsystems. Russell & Stoll type (R&S) connectors are recommended for 60-Hz systems.
Note: Each disk array frame requires two power connections to ensure power redundancy. It
is strongly recommended that the second power source be supplied from a separate power
boundary to eliminate source power as a possible single (nonredundant) point of failure.

Comments
If using three-phase power, the
Controller Frame receives its input
power from the first disk array frame. All
Controller single-phase features must be
removed to allow three-phase power for
the Controller.
Consists of two AC Boxes
