1.0 INTRODUCTION
The Emerson Network Power
®
MPH2
™
is the most intelligent, high-availability line of managed rack
PDU’s. 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 outlet levels, as well as integration with environmental sensors. The available
information varies by type of MPH2.
Mounting
Rack PDU’s are available for mounting in vertical configuration in standard or network enclosures.
Power cords on MPH2 models that mount vertically in a zero-U configuration may be switched from
one end to the other to accommodate top or bottom cable entry into the rack.
Locking Outlets - IEC Type Only
Locking outlets are available on models with IEC outlets. The locking feature requires optional power
cords to be installed on devices powered by the MPH2.
The outlets require no modification to function properly with non-locking power cords.
Overcurrent Protection
All MPH2 rack PDU units with input current rating of 30A 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 rack PDU’s with two or three branch circuits.
Standard-profile circuit breakers are used on MPH2 rack PDU’s that have six branch circuits or have
a 240VAC rating. Each type of circuit breaker is a flush-mount, rocker style (see Figure 29).
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 four rack PDU’s for monitoring and management.
A rack PDU can be monitored locally through its onboard LCD, through a Web interface or through
an optional display module, either the RPC BDM (Part# RPCBDM-1000). The display module
connects directly to the RPC2 communications module. It can be handheld, mounted in or on the rack
or mounted on a wall near the rack PDU it is monitoring.
Multiple MPH2 rack PDU’s can be managed with these software applications:
•Avocent
®
Rack Power Manager software
•Avocent DSView
™
management software
• Emerson’s Trellis
™
Real-Time Infrastructure Optimization platform software
•Liebert
®
Nform
®
, which adds group-based outlet management
• Liebert SiteScan
