SNMP/ Modem slots for remote monitoring/control
Simple Network Management Protocol (SNMP) is a world-wide, standardised communication protocol that can be used to
monitor any network-connected device via a simple control language and display the results in an application running
within a standard web browser.
The PowerWave 9000 contains two SNMP slots; one is designed to house a Modem/Ethernet SNMP adapter card and the
other a Modem/GSM adapter (see Figure 7.1). Alternatively, SNMP connectivity can also be implemented using an
external SNMP adapter connected to the UPS RS232 output (JD11).
An SNMP/Ethernet adapter contains an RJ-45 connector which allows it to be connected to the network using a standard
network cable. Once connected, the UPS-Management software agent, which is already installed in the SNMP adapter,
then monitors the UPS operating parameters and outputs its data in SNMP format to the connected network. In a multi-
module UPS system the SNMP interface can communicate ‘system-wide’ data or data for an individual UPS module.
The SNMP adaptor requires a PC with terminal connections, and for normal operation at least one network connection
(Ethernet) is also required.

UPS Monitoring and automated control software
7.6.1 The importance of UPS management
The utility supply is inevitably unreliable every now and then; and assuring continuous power to all the facilities connected
to it can be a difficult task. The situation is further complicated if worldwide systems are managed via a Local Area
Network (LAN) or Wide Area Network (WAN).
However, by using the PowerWave 9000 UPS system in conjunction with purpose-designed network management tools, a
systems administrator can take measures to back-up data and prevent system errors or data loss even in the event of a
relatively long utility supply outage. In the case of an abnormal utility supply, suitable UPS management software will also
enable a system administrator to monitor all concerned networks from a central point and identify bottlenecks at an early
stage.
In spite of extensive system monitoring, if an administrator fails to intervene in a timely manner serious damage can still
occur. It is important therefore that the installed UPS software will react automatically in such a case and shut down the
supplied system in a safe and controlled manner.
Uninterruptible Power Supplies Ltd considers it important to have a complete solution for its UPS systems, and offers its
customers a number of remote control and monitoring tools to provide optimum protection.
