Power Components
The Silicon Graphics Prism platform can contain the following power components:
• One or two power distribution units (PDUs). The second PDU is added to the
system only when more than 10 AC power receptacles are needed within the rack.
The PDU inputs AC voltage from an external power receptacle and it can output
AC voltage to the base compute modules, XG2N graphics modules, CPU expansion
modules, CMPX modules, router modules, and TP900 storage modules.
See Figure 1-9 on page 14 for an example.
