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.
Figure 1-17
Connecting Multiple Modules to a PDU
An optional three-phase PDU (used in 42U system racks only) has 18 outlet connections, of which
up to 16 may be needed to power eight IRUs. Each three-phase rack system houses a single PDU.
