Power Distribution Units (PDUs)
If your system includes the optional rackmounted HP R5500 XR UPS, the modular
cabinet will have one PDU located on the rear left side and four extension bars on the
rear right side. The PDU and extension bars are oriented inward, facing the
components within the modular cabinet. To provide redundancy, components are
plugged into the left-side PDU and the extension bars. Each extension bar is plugged
into the UPS. This illustration shows the AC power feed cables for the PDU and UPS
for AC power feed from the top of the cabinet when the optional UPS and ERM are
installed:
