Power Configuration; Dynamic Power Capping; Hp Bladesystem Enclosure Single-Phase Power Configuration - HP BL685c - ProLiant - 4 GB RAM Site Planning Manual

Wiring connections must be properly torqued. Many equipment manufacturers specify the proper
connection torque values for their hardware.
Ground connections must only be made on a conductive, nonpainted surface. When equipment vibration
is present, lock washers must be used on all connections to prevent connection hardware from working
loose.
Data communications cables
Power transformers create high-energy fields in the form of EMI. Heavy foot traffic can create ESD that
can damage electronic components. Route data communications cables away from these areas. To
reduce the effects of external fields, use shielded data communications cables that meet approved industry
standards.

Power configuration

HP BladeSystem enclosures can be powered from single-phase AC, three-phase AC, or from -48V DC site
power sources. These options are available at the time of purchase through either the Build-to-Order or
Configure-to-Order processes.
Existing units can be converted from one power source to another when necessary. For more information
on converting an enclosure power source, see the HP website (http://www.hp.com/go/bladesystem).

Dynamic Power Capping

The Dynamic Power Capping feature limits the power consumption of the enclosure through enclosure
Dynamic Power Cap settings within the Onboard Administrator. The enclosure Dynamic Power Cap is
shared among all of the installed devices. Individual server blade power allotments are changed to match
the server blade load. This feature optimizes the performance of the server blades while ensuring that the
enclosure electrical load stays below the Dynamic Power Cap value.
