Figure 3-1, Example Duplex Configuration, on page 3-14 shows components installed
in 42U modular cabinets. Cabinet weight includes the PDUs and their associated
wiring and receptacles.
Power and thermal calculations assume that each enclosure in the cabinet is fully
populated; for example, a NonStop Blade Element with four processors. The power
and heat load is less when enclosures are not fully populated, such as a NonStop
Blade Element with fewer processors or less memory, a Fibre Channel disk module
with fewer disk drives, or an LSU enclosure with fewer LSUs.
AC current calculations assume that one PDU delivers all power. In normal operation,
the power is split equally between the two PDUs in the cabinet. However, calculate the
power load to assume delivery from only one PDU to allow the system to continue to
operate if one of the two AC power sources or PDUs fails.
Note. 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. To provide redundancy, components are plugged into the left-side PDU and the extension
bars. Each extension bar is plugged into the UPS.
