Emerson Liebert MPX PEM 230/400VAC 63A MPXPEM-EHBEXZ30 User Manual

A Liebert

®

 MPX

™

 can be operated with or without the optional Liebert RPC

™

 (Rack PDU Card). The 

card employs a Web-based interface to enhance monitoring and control, enabling users to manage 

rack equipment locally or from a remote location. The Liebert RPC can be used to determine power 

usage, switch receptacles on some units On and Off and troubleshoot input power supply problems.
The Liebert RPC will manage and monitor different types of MPX BRMs (Branch Receptacle 

Modules) installed on the same Liebert MPX. The feature can be valuable when some rack equipment 

connected to the Liebert MPX requires closer monitoring than other equipment.
The Liebert RPC supports managing and monitoring the Liebert MPX with SNMP, Liebert Nform

™

, 

Liebert SiteScan

®

 and third-party management systems.

When connecting the rack equipment to the Liebert MPX’s receptacles, arrange cables and 

connections to avoid tangling and crisscrossing the power cables. For power management purposes, 

record the receptacle where each piece of equipment is connected. Receptacles on the Liebert MPX 

have a numerical designation. A Liebert MPX with more than one circuit has the outlets named with 

numbers and are grouped by branch with a number referring to the proper circuit breaker.

The Liebert RPC is factory-configured for DHCP. If you require a Static or BootP network 

configuration, be sure to change the Boot Mode, as described below:
1. Insert an additional Ethernet cable (not included) into the Liebert RPC’s 

Expansion/Management port, identified by the icon on the right:

2. Insert the other end of the Ethernet cable into a computer.
3. Configure the computer’s IP settings to communicate on a 192.168.1.X network:

4. To connect to the card, open a Web browser and enter http://192.168.1.10 into the URL field, then 

press Enter.

5. Once the Rack PDU Web page is displayed, click the Configure tab, then click Network 

Settings in the left pane.

6. When prompted for a user name and password, enter Liebert (case sensitive) for both.

7. Click OK.
8. Click Edit in the right pane.
9. The default Speed/Duplex for the Ethernet port is Auto (automatic). To change this, choose from 

the Speed/Duplex drop-down list.

10. Choose the Boot Mode: DHCP, Static or BootP. (The default is DHCP.)
11. Click Save to save any changes (or Reset to cancel). A Notice window displays a reminder to 

reinitialize the card.

12. Click OK.
13. Make other changes as needed in the Configuration tab.
14. To complete the configuration, click Reinitialize in the left pane. A Reinitialize button appears 

in the right side of the window.
