With powerful alarm collection (64 discretes), 8 serial ports, two separate Ethernet cards, SNMP v3 support, and versatile alarm reporting via SNMP Trap, email and text message, the NetGuardian 864A G5 can handle any alarm monitoring need.


Key Features

  • Monitors up to 8 analogs
  • Controls up to 8 relays
  • High-capacity RTU with 64 discrete alarm points
  • Pings up to 32 network elements
  • 8 RS232 ports for increased terminal server functionality

The NetGuardian 864A G5 is a powerful, compact LAN-based alarm collector that provides network managers with remote visibility of their IP network elements. With 32 ping alarms, 64 discrete alarms, 8 analog inputs, and 8 controls, this versatile unit is the ideal network monitoring solution.

If an element fails to respond to successive pings, or if anything goes wrong with the environmental controls, the NetGuardian 864A notifies personnel using a variety of methods with a complete status message. Notification types include email, text messages, SNMP trap messages, and pager. The unit also stores up to 100 events in its event log.

In addition to network and environmental alarms and controls, the NetGuardian also acts as a terminal server for 8 serial ports, thereby eliminating the need for dedicated circuits and the recurring monthly costs associated with such transports.

The NetGuardian 864A is easy to install, with connectors for all serial and LAN ports, alarm, analog, and control wiring. A hinged back panel with all wire wrap connections is also available for other installation options. The unit mounts quickly in either 19" or 23" equipment racks while occupying only one rack unit of space.

Provisioning of the NetGuardian 864A can be easily accomplished using any Web Browser or generic TTY terminal. This can be done on-site, using the front panel craft port, or remotely via LAN (TELNET) or dial-up modem. The entire configuration is saved on the NetGuardian 864A where it remains secure through power outages in non-volatile RAM.

The NetGuardian 864A's web browser interface is easy and convenient for alarm management and for unit configuration via the Internet or Intranet. The user-friendly interface allows complete access to all the functions of the unit and enables the user to quickly set up alarm point descriptions, view alarm status, issue controls, and configure notification information, as well as additional options.

Additional options include a built-in sensor power supply, dual power feeds, integrated temperature and battery sensors, and external temperature sensor port.

The versatility, capacity, and reliability of the NetGuardian 864A are the reasons why it is the standard for network alarm monitoring needs.
