Modular PDU

HP recommends using power distribution units (PDUs) in installations where a number of
server units can place serious loading demands on the AC power bus. HP offers PDUs
that provide safety and reliability to multi-server installations.
The PDUs described in this white paper offer 0U and 1U mounting options and feature
circuit-breaker protection of equipment in groups.
Figure 1 shows a PDU using the 0U rack
mounting option. This configuration may be
preferable in a high-density installation
requiring the maximum amount of vertical
space for servers and other active
components. The 0U configuration offers
the following advantages:
Saves vertical rack space for
equipment requiring more operator/
maintenance accessibility.
Easy access to power connections
Figure 1. 0U Rack Mounting Option
The Modular PDU consists of a control core that connects to the power bus (or to a UPS)
and four extension bars that distribute power to the equipment groups. The control core
includes a 15A circuit breaker for each of the four C19-type extension bar outputs.
Available in low- and high-voltage versions, the modular PDU comes with three types of
extension bars to accommodate a variety of distribution requirements. The control core
may be rack-mounted in a 0U or 1U configuration. The extension bars include both
single-bar and double-bar mounting brackets for attachment to vertical rack supports.
Several versions of Modular PDUs are available to meet a variety of electrical
requirements as indicated in Table 3.
Figure 2 shows a PDU using the 1U rack
mounting option. This configuration may be
preferable in installations where operator
or maintenance accessibility to all
components is key. The 1U configuration
offers the following advantages:
Easy access to all switches and circuit
beakers.
Easy viewing of circuit status LED.
Easy access for service replacement or
upgrade.
