5.0 OPERATION AND CONFIGURATION
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.
5.1 Configure the Liebert RPC
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.
15. Click Reinitialize in the right pane to commit the changes and reboot the card. The card is now
fully operational.
NOTE
The Liebert RPC’s Expansion/Management port should be used ONLY for local configuration
through interconnection to a computer or for interconnecting an additional Liebert MPX or
Liebert MPH
™
.
