Example 3: Dual Expansion Cabinet System (Field-Integrated)
Figure 3-13 shows a field-integrated system with two expansion cabinets. Note these
features:
• A second (switchless) PDU (identified as the UPS PDU) has been installed in each
expansion cabinet. The UPS PDU in the left-hand expansion cabinet receives its power
from the 30A connector on the PowerTrust UPS located in the right-hand cabinet. The
UPS PDU in the right-hand cabinet receives its power from the IEC320 connector on
the same PowerTrust UPS.
• Peripherals in the expansion cabinet should be powered via the UPS PDU whenever
possible. If either the UPS or PDU ratings are insufficient to power all of the
peripherals, the switched PDU is still available for powering the additional peripherals,
but they will not be protected by the UPS.
• The system console is being powered from the switched PDU, not the UPS PDU; it is not
protected by the PowerTrust UPS. It is recommended that the console be protected by
the UPS.
• The system SPU is being powered from the 30A output of the PowerTrust UPS in the
left-hand expansion cabinet.
• The expansion cabinet fan is powered from the UPS PDU, to ensure that the cabinet is
cooled in the event of power failure.
