Calculating Specifications for Enclosure
Combinations
The example configuration in this subsection shows listed components installed in a
single modular (42U) HP modular cabinet. 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. The power and heat load is less when enclosures are not fully populated,
such as a Fibre Channel disk module with fewer disk drives.
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.
