User Manual
1.0 Introduction
The Emerson Network Power
®
MPH2
™
is the most intelligent, high-availability line of managed rack PDUs.
It offers remote monitoring and control capabilities as well as environmental sensors with multiple power
input selections and output configurations.
Metering Levels
Four types of MPH2 are available that offer metering of all electrical information including input, branch
and receptacle levels, as well as integration with environmental sensors. The available information varies
by type of MPH2. See 1.2 - Model Types, page 7 for descriptions.
Mounting
Rack PDUs are available for mounting in vertical and horizontal configurations in standard racks or
network enclosures.
Because the power cord is connected at the end of the vertical-mount (0-U) MPH2 models, the rack PDUs
may be oriented to accommodate top or bottom cable-entry into the rack.
Locking Receptacles - IEC Type Only
Locking receptacles are available on models with IEC receptacles. The locking feature requires optional
locking power cords to be installed on devices powered by the MPH2.
The receptacles require no modification to function properly with non-locking power cords.
Overcurrent Protection
All MPH2 Rack PDU units with input current rating of 30 A and higher feature 100% rated
hydraulic-magnetic breakers. For all UL-listed models, the maximum cord and plug-connected loading is
limited to 80% continuous loading, as required by UL in accordance with the National Electric Code.
Low-profile circuit breakers are used on all MPH2 0-U Rack PDUs with two or three branch circuits.
Standard-profile circuit breakers are used on MPH2 horizontal models and on certain vertical models that
have 6 branch circuits or have a 240 VAC rating. Each type of circuit breaker is a flush-mount, rocker style
(see Figure 3-17).
Integrated Monitoring and Management
The factory-installed Emerson RPC2
™
communications module permits managing the MPH2 Rack PDU
over a secure Web page and SNMP-based network management system. The RPC2 permits
interconnecting up to 4 rack PDUs in a Rack-PDU array configuration for monitoring and management.
NOTE
Do not interconnect RPC-1000 with RPC2 Rack PDUs in an array. They are incompatible and will
not interoperate.
NOTE
Refer to the RPC2 communications module user manual, SL-20841, for detailed instructions on
installing and using the RPC2 module. The document is available at Emerson’s Web site:
