Figure 2 shows a PDU using the 1U rackmounting option. HP recommends this configuration in
installations where maximum accessibility to all components is important. 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

Modular PDU
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 15-A circuit
breaker for each of the four IEC C19 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 rackmounted 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 1.
