Connection to IP networks
There are 2 ways of connecting a UPS to an IP network:
◗ adding a network management card to the UPS which becomes the interface to the network.
◗ using a nearby PC or server connected to the network as a proxy.
Network Management Card
These cards are recommended for central UPS systems that protect a complete network
or for UPS systems providing back-up for critical equipment.
With its embedded card, the UPS has its own IP address with local intelligence to:
◗ serve Web pages with reports, settings and alarms;
◗ interface with SNMP-based network management consoles such as HP Openview, IBM Tivoli
Netview and Computer Associates Unicenter;
◗ communicate with shutdown software installed on the servers to be protected.
A more specialised XML/Web card is recommended for the advanced supervision of three-phase UPS’s
Network Management Proxy
The NMP is a more economical solution for small UPS systems. It allows a UPS to be
controlled over the network without adding to the basic cost of the UPS.
The proxy software agent is installed on the system to which the UPS is connected via a
USB or RS232 port.
The NMP agent provides both XML and SNMP protocols and is used to manage a UPS
remotely using a standard browser or a network management console.
Protection: shutting down servers
To ensure system and data integrity, a computer operating system must be shut down
in the correct sequence.
A software module must be installed on the protected servers to automate various
functions in case of a power problem, such as:
◗ executing a script to close all applications running on the server;
◗ initiating a shutdown sequence or hibernation after a pre-set timeout or just before
total battery discharge to maintain service continuity;
◗ restarting the operating system automatically or in manual mode when the mains
power is restored;
◗ personalising alarm messages for events concerning the UPS, etc.
MGE shutdown modules can be used with both Network Management Cards as well as
with the Network Management Proxy.
The shutdown module is a highly efficient
program with quiet installation and
centralised configuration.
UPS systems supervision
Supervision using a Web browser
UPS systems can be supervised using a standard Web browser to provide
details of all UPS parameters, measurements and settings, from any point in
the network, simply using the IP address of each UPS.
Supervision using a Network Management System
Enterprise network administrators have the same level of details for UPS
systems as for servers and switches using one of the snap-ins designed for
the best known Network Management Systems, such as HP OpenView, IBM
Tivoli and CA Unicenter. MGE UPSs meet SNMP standards (MIB RFC 1628 or
MIB MGE), which cover all the MGE UPS SYSTEMS product specific functions.
They can be easily incorporated into Network Management Systems or server
management systems such as HP/Compaq Insight Manager 7 for auto-
detection, monitoring, colour-coded alarms on each device's icon, etc.
