Connecting System Modules to a Rack Power Source

If your Altix 450 system is shipped from SGI in a rack, there will be at least one power distribution unit (PDU) installed in the rack. Note that each single-phase PDU can support a maximum of two Altix 450 IRUs. Plug both power cords from each IRU into the PDU(s) installed in your short or tall rack.

Figure 1-17 shows an example of cabling the system modules that reside in a rack to a PDU.
