Example 1: Single Expansion Cabinet System
(Field-Integrated)
Figure 3-11 shows a field-integrated system with one expansion cabinet. Note these
features:
• A second (switchless) PDU (identified as the UPS PDU) has been installed. This PDU
receives its power from the IEC320 C19 connector on the PowerTrust UPS.
• For this example, all peripherals in the cabinet are being powered via the UPS PDU. 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 UPS PDU.
• The system SPU is being powered from the 30A output of the PowerTrust UPS.
• The expansion cabinet fan is powered from the UPS PDU to ensure that the cabinet is
cooled in the event of power failure.
