1.0 INTRODUCTION
The RPC2 communications module is a network interface module that provides network connectivity
to the Liebert
®
rack PDU family of products.
The RPC2 (Rack PDU card) is factory-installed installed in managed versions of Emerson Network
Power’s MPH2
™
Rack PDU’s. It can be field-installed in Liebert MPH
™
and Liebert MPX
™
rack PDU’s
to provide network monitoring and control capabilities.
The module is factory-set for service in DHCP-based applications. It can be quickly and simply
configured for duty in static IP applications.
The RPC2 serves as the integration point for several rack accessory products. Available options
include a handheld display, the RPC BDM, to view monitoring data and Liebert SN
™
sensors that
may be connected to monitor temperature, humidity, door contacts and digital inputs.
1.1 Features and Benefits
Interoperability
The RPC2 communications module integrates network management of the MPH rack PDU family
and environmental sensors with a local display interface. This ensures consistency of information
available to both remote and local users — those in the data center — thus reducing mistakes during
commission/decommission.
Cable Standardization
The RPC2 communications module uses standard cables that are readily available in a data center;
no special cables are required. The LAN port is compatible with 1Gbps Ethernet speeds with the
recommended CAT5E or CAT6 Ethernet cabling. The USB port connection uses standard USB
cabling.
Consolidation of IP Addresses
The RPC2 communications module can be used to create a Rack PDU Array
™
by interconnecting
multiple MPH2 Rack PDUs to minimize the number of IP addresses, consolidate monitoring and
reduce overhead.
Receptacle Group Control
The RPC2 communications module enables grouping receptacles to apply the same action to all
receptacles in the group with one operation. It also permits monitoring and management of receptacle
groups through Liebert Nform
™
software.
MPH2 Rack PDU Power Conditioning Monitoring
The RPC2 communications module enables monitoring of Emerson’s MPH2, Liebert MPX and Liebert
MPH rack PDU’s collectively known as Liebert and Emerson Network Power rack PDU. It provides
rack PDU receptacle voltage and current draw, provides load balancing capability and monitors rack
environmental conditions.
Energy Metering
The RPC2 communications module reports power consumption (kWh) at the PDU, branch and
receptacle levels as calculated by the MPH2’s circuitry.
Receptacle Load Control
The RPC2 communications module interface permits controlling the power-up / wake-up state and
sequencing of receptacles.
Local Display Support
The RPC2 communications module provides an interface for a display option, the RPC BDM, to
facilitate installation and local troubleshooting of interconnected MPH rack PDUs. The display may
be user-mounted on or near racks for optimal placement and viewing.
Event Notifications
The RPC2 communications module sends comprehensive event notifications via SNMP, e-mail, SMS
text messages and cellular paging. It also provides notification status via a Web page.
