1. Introduction
A UPS can be configured with either an internal or an external SNMP-32 card; this SNMP-32 card is then connected to the network. The SNMP-32 card contains a MIB agent. The agent communicates both solicited and unsolicited messages to the Network Management Station (NMS). Unsolicited messages are defined by the MIB and are built into the agent for critical items such as AC power failure and low battery detection. The agent recognizes these critical events and immediately forwards them to the Network Management Station. The network manager will immediately notice the alarm and the flashing icon of the SNMP-32 card. By clicking on the icon, you will be able to see the alarm messages. If nobody is present, the Network Management Station will shutdown the programs, the OS server and eventually the UPS safely.
1-1. Features
The SNMP-32 card connects directly to your UPS. It runs an embedded Simple Network Management Protocol (SNMP) software agent. This agent responds to SNMP GETS and SETS and also forwards traps to designated recipients when critical conditions occur within the UPS, such as the UPS going on battery backup mode during a power failure.
The SNMP-32 card features:
•Internet ready — It supports TCP/IP, UDP, SNMP, Telnet, SNTP, PPP, HTTP and SMTP protocols. The user can use a SNMP manager or a Web browser to monitor the UPS through a network.
•Multiple OS support — As long as there is Network Management software present.
•Remote setup support — Once an IP address is assigned the rest can be setup remotely through Telnet or a Browser.
•Remote monitoring — Monitors the status of one UPS from a remote workstation (Web browser or NMS).
•Remote Control — Turns the UPS off (or a battery test) when the NMS sends the proper command.
•NMS To Receive UPS Alarms — These traps (unsolicited messages) inform the user about the power condition of the connected UPS.
•Works with most major NMS on Ethernet — SNMP-32 card works with the most widely used Network Management Systems: HP Open View, Sun NetManager, IBM NetView, and many more.
•Remote Software upgrade — The SNMP-32 card supports Software upgrade through the Ethernet remotely.
•Daily historical reports — Automatically emails daily history reports to the specified users.
•Auto-Sense — Auto-Senses 10/100M Ethernet.
•Event Notifications — Sends both SNMP Traps and Emails for event notification.
•3-Ports — Environmental Monitoring (Optional Kit), External Modem, and Ethernet.
