A PDU using the 0U rack mounting
option is shown in figure 4. 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
A PDU using the 1U rack mounting
option is shown in figure 5. 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 breakers
• easy viewing of circuit status LED
• easy access for service
replacement or upgrade

modular PDUs
The Modular PDU consists of a control unit that connects to the power bus (or to
a UPS) and four extension bars that distribute power to the equipment groups.
The control unit 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 a choice of three types of extension bars to accommodate a
variety of distribution requirements. The control unit may be rack-mounted in a
0U or 1U configuration. The extension bars include mounting brackets for
attachment to vertical rack supports.

Control Unit Extension Bar (I of 4)
Depending on configuration, extension bar deployment may be optional (i.e.,
equipment may be connected directly to the control unit with the appropriate
jumper cord). Several versions of Modular PDUs are available to meet a variety
of electrical requirements as indicated in table 5.
