*Click an image to enlarge

With FrameRelay/T1 support, an integrated 7-port hub, industrial temperature rating, and powerful alarm collection and reporting, the NetGuardian 216T can effectively monitor outdoor enclosures and provide Ethernet to sites without existing LAN.

Key Features

  • 7 analog alarms (4 general, 1 temp, 2 batt)
  • 2 control relays
  • 16 discrete alarms
  • LAN access for 7 network elements
  • 32 ping alarms
  • FrameRelay and PPP/T1 support for added versatility and responsiveness to dynamic network growth
  • Web browser support for monitoring and provisioning the units

The NetGuardian 216T is a powerful, compact LAN- and T1-WAN-based alarm collector that provides network managers with remote visibility of their network elements. With FrameRelay/T1 support, LAN access for 7 network elements, 16 discrete alarms, 32 ping alarms, 7 analog inputs (4 for general use, 1 for temperature, 2 for batteries), and 2 controls, this versatile unit is the ideal network monitoring solution for outdoor enclosures in areas without existing LAN.

When a problem occurs, the NetGuardian 216T notifies personnel with a complete status message. Notification types include SNMP Traps, text message, TCP text, T/MonXM, Email, and paging through email. The unit also stores up to 100 events in its event log.

In addition to network and environmental alarms and controls, the NetGuardian also includes terminal server functionality, allowing remote Telnet access to an external serial device. The NetGuardian is available in 1 or 5 port models.

The NetGuardian 216T is easy to install, with connectors for all serial and LAN ports, as well as alarm, analog, and control wiring. A 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 216T 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, T1 WAN, or dial-up modem. The entire configuration is saved on the NetGuardian 216T where it remains secure through power outages in non-volatile RAM.

Additional options include an external temperature sensor and a wire-wrap back panel for alternate connectivity options.

The versatility and reliability of the NetGuardian 216T make it an excellent choice for both inside- and outside-plant operations.
