7.3 SNMP adapters

Figure 7.2 SNMP Adapters

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 a browser-based application.

The UPS management software can make your UPS data available in this SNMP format thanks to the

software agent built in to the SNMP adapter. Uninterruptible Power Supplies Ltd offer software with SNMP

functionality for Novell, OS/2, and Windows that run both on INTEL and on ALPHA, DEC VMS and Apple.

Two models of SNMP adapters are available for use with the PowerWave 1000, both of which share the

same functionality. An internal SNMP card can be fitted into the communications card expansion slot located

on the UPS rear panel and communicates with the UPS via a serial interface. An optional external SNMP

adapter can be used, located remotely and connected to the UPS via its RS232 port.

The SNMP adapter can be configured via Telnet, http (browser) or serial connection. For normal operation, at

least one Ethernet network connection is necessary. Further details are provided in the manual that is

supplied on the WAVEMON installation CD.

RCCMD

RCCMD (Remote Console Command Module) for ‘multi-server shutdown’, is an independent software

module intended for transmitting and receiving ‘remote commands’. The new version RCCMD2 is, similar to

WAVEMON, available for the most widespread operating systems. Using the ‘RCCMD send’ function, the

SNMP adapter can send status messages to connected users or initiate automatic shutdown throughout the

whole network. Our SNMP adapters are fully compatible with RCCMD.

7.4 AS400 (dry contact) card

The DCE dry contact card provides volt-free

outputs that can be used for the automatic and

orderly shutdown of servers (AS400) or used as

control inputs to building management systems.

The signal descriptions of the 10 pins of the dry

contact card are shown below. Note that all pins

except Pins 9 and 10 (which are isolated) are

link-selectable to be either short-circuited or

open-circuited to the common Pin 8 when the

monitored parameter is ‘active’.

The pin assignment of the 10-pin terminals are:

To shut down the UPS, you must connect a DC voltage of 5.5V~25V between pin 9 (+) and pin 10 (-).
