HP BladeSystem p-Class rack-centralized (3U) power solutions

Because the enhanced server blade enclosure splits the DC power into the left and right sides of each
server blade enclosure, customers must use two power enclosures to configure AC line cord
redundancy. Line feed redundancy is achieved between sides A and B of the two power enclosures
by wiring enclosure 1 side A to AC input 1, and enclosure 2 side A to AC input 2, as shown in
Figure 3.

Combining standard and enhanced server blade enclosures
Some customers may choose to deploy both standard and enhanced server blade enclosures in the
same rack to share the same power subsystem. Before doing so, administrators should be aware of
firmware and redundancy requirements. HP encourages customers to upgrade standard server blade
enclosures with the Server Blade Enclosure Upgrade Kit to take advantage of enhanced backplane
components and provide a single, physical iLO port for the enclosure.
