3.5 Installing Optional Items
The following items may be added to an MPH2™ Rack PDU system but are not required:
•
RPC Basic Display Module
•
Liebert® SN temperature/humidity sensors
3.5.1 RPC Basic Display Module Installation
The RPC Basic Display Module (BDM) provides local display of parametric data, including electrical status,
temperature and humidity for all connected MPH2™ Rack PDUs. Display information is accessed via a
navigation switch on the BDM. The RPC BDM is connected by cable to the MPH2™ Rack PDU, allowing the
user to install the display to suit the local reading preferences. A 6.5-ft. (2-m) cable and general mounting
provisions are provided. A single display can be used for up to four rack PDUs connected in a Rack PDU
Array™.
The RPC BDM can be mounted in the rack with either the included hardware or with a cable tie through
the slot on the back of the module. Either method permits moving the BDM to a different place in the
same rack or to another rack.
NOTE: See the RPC2™ Communications Module Installer/User Guide for more detailed information
about operating the BDM.
