1 INTRODUCTION
The Rack PDU Card (RPC2™) Communications Module provides network connectivity to the Vertiv™ rack PDU family of
products.
The RPC2™ communications module allows you to monitor the components connected to the rack PDU using various tools,
including the module's web user interface and optional units, the Basic Display Module (BDM) device and Liebert® SN™
sensor. The handheld display, the RPC BDM, allows you to view monitored data and the Liebert® SN™ is a sensor that can
be connected to rack PDUs to monitor temperature, humidity, door contacts and digital inputs.
The RPC2™ is factory installed in managed versions of the Vertiv™ MPH2™ Rack PDUs. It can be field-installed in Vertiv™
MPH™ and MPX™ rack PDUs to provide network monitoring and control capabilities. The communications module is
factory set for service in DHCP-based applications. It can be configured for static IP applications.
In this guide, you will find sections dedicated to explaining how to use the web interface, as well as the optional devices.
These devices, used in conjunction with the RPC2™ communications module, give you easy access to the data from the rack
PDUs.

2.3 Monitoring and Configuration Overview
The following sections outline how rack PDUs are configured and managed.
2.3.1 Vertiv™ Rack PDU monitoring structure
Vertiv™rack PDUs are managed at three levels:
•Rack PDU Level - provides aggregate input power monitoring of rack PDUs.
•Branch Level - provides status information of a branch circuit breaker and aggregate power monitoring of
branch receptacles.
Vertiv | RPC2™ Communications Module Installer/User Guide | 4

•Receptacle Level - provides status information and power monitoring of each receptacle (available on certain
models of the Vertiv® MPH2™ and MPX™ rack PDUs).
2.3.2 Rack PDU component ID
An alphanumeric ID consisting of up to three parts helps you identify components when displayed on the web interface or
the RPC BDM device. The component ID uses the format PDU-Branch-Receptacle. For example, the component ID 1-A-3
identifies PDU1, Branch A and Receptacle 3.
NOTE: MPH2™ rack PDUs use alphabetical characters to designate a branch whereas MPX™and MPH™ rack PDUs
use numerical characters. So Branch Aon an MPH2™ PDUis effectively Branch 1 on an MPX™or MPH™ PDU.
Figure 2.3 MPH2™ Branch and Receptacle Labeling Example
ITEM DESCRIPTION
1 Letters displaying the branch level.
2 Numbers displaying the receptacle level.
Table 2.3 Rack Component ID Descriptions
2.4 Creating a Rack PDU Array
Up to four MPH2 or Liebert MPX rack PDUs may be integrated into a rack PDU array, which permits central control and
monitoring of each rack PDU through a single web interface. Each rack PDU must have an RPC2 communications module
installed.
NOTE: Creating a Rack PDU array does not require rebooting or powering off either the MPH2 rack PDUs or the
connected load. The level of monitoring and control depends on the model of rack PDU.
To set up a rack PDU array:
1. Log in with the required privileges.
2. Connect an Ethernet cable from a computer or network switch to the Network port of the master RPC2
communications module.
3. Connect an Ethernet cable to the Link port of the master RPC2 communications module.
4. Connect the other end of the Ethernet cable to the network port of a slave RPC2 communications module on a
second MPH2. This RPC2 module is a sibling unit, accessible through the master RPC2 module.
NOTE: The RPC2 module connected to the LAN is the master and is positioned first in the rack PDU array.
5. The second RPC2 communications module automatically detects the connections and is discovered as a
sibling unit.
NOTE: If the sibling order needs to be changed, disconnect the cabling for 30 seconds and then reconnect in the
desired sequence. You do not need to reboot or power cycle the module.
6. Connect additional RPC2 communications modules as shown in the following figure. The Ethernet cable
attaches from the link port of an RPC2 module that has been added to the array to the next module’s network
port. Each newly added module is discovered as the next sibling.

NOTE: MPHX BRM, MPH2-C, MPH2-M and MPH2-Rrack PDUmodels support the circuit breaker status. MPH2-B rack
PDUmodels utilize a software Loss of Load detection, which detects a sudden reduction of branch current after its
overcurrent alarm threshold is breached. This active event implies the circuit breaker has opened.
To edit a branch:
1. Log in with the required privileges.
2. From the PDU Explorer tab, click the rack PDU with the branch to be edited.
3. Click in a branch field to highlight the branch and open its receptacle window.
4. In the table at the bottom of the window, click the Settings tab.
5. Check the boxes next to the settings to be edited.
6. Click the Edit icon.
7. Enter the new values.
-or-
Use a drop-down menu to do one of the following:
•Enable or disable software overcurrent protection.
•Change whether the branch is designated critical or non-critical.
8. When finished, click the Save icon to make the change or click the Cancel icon to abort the change. The icons
will be in the column formerly occupied by the Edit icon.
3.4.5 Receptacle settings
The following procedures help you configure the receptacle settings. Review the table in this section for the receptacle
settings descriptions.
SETTING DESCRIPTION
Over Current Alarm Threshold Percentage of receptacle current rating to exceed before the corresponding event notification occurs.
Over Current Warning Threshold Percentage of receptacle current rating to exceed before the corresponding event notification occurs. The
value must be less than the alarm threshold.
Under Current Alarm Threshold Percentage of receptacle current rating to fall below before the corresponding event notification occurs.
The value must be less than the warning threshold. Azero value disables the alarm.
Power Up State
After mains power is applied, the receptacle is either immediately turned on, turned off or is restored to the
last power state before the loss of power occurred and after the Power On Delay has expired. If the last
power state was off, the power remains off.
Power On Delay The amount of time, in seconds, before the receptacle power is restored after mains power is applied.
Power Cycle Delay The amount of time, in seconds, that receptacle power is momentarily turned off.
Post On Delay The amount of time, in seconds, before receptacle power is turned on.
Post Off Delay The amount of time, in seconds, before the receptacle power is turned off.
Software Over Temperature Protection
(SWOTP)
If enabled, affected receptacles automatically have power turned off after the measured temperature
breaches the over temperature alarm threshold of a temperature sensor for at least the duration of the
SWOTP delay. The SWOTP can be configured for local mode which is only affected by alarm of
temperature sensor(s) connected to its RPC2 module, or array mode which is affected by alarm of
temperature sensor(s) connected to any RPC2 module in the array.
Receptacle Criticality
If disabled, the receptacle automatically turns off if SWOTP is enabled and the condition is active. SWOTP
automatically turns off receptacle power to non-critical and unloaded receptacles (no current draw) when
input and/or branch overcurrent alarm conditions occur in order to mitigate a possible opening of circuit
breakers in the unit or upstream at the service.
