New Product Announcement: The NetGuardian 832A G4

FRESNO, CA, April 4, 2006- DPS Telecom today announced a major new update to its best-selling NetGuardian 832A remote telemetry unit. The NetGuardian 832A G4 update adds support for SNMP v2c and the SNMP INFORM message type; dual NICs; highspeed serial ports; customizable alarm severity levels; global support for reporting to dual SNMP managers; plus many under-the-hood improvements.

The NetGuardian 832A G4 is a powerful, compact LAN-based alarm collector that provides network managers with remote visibility of their IP network elements. With 32 ping alarms, 32 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 832A notifies personnel using a variety of methods with a complete status message. Notification types include SNMP Traps, alphanumeric pager, numeric pager, text message, TCP text, T/MonXM, and E-mail. 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 832A is easy to install, with connectors for all serial and LAN ports, alarm, analog, and control wiring. Hinged back panels with all wire wrap or pluggable connections are 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 832A 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 832A where it remains secure through power outages in non-volatile RAM. Additional options include NEBS Level 3 certification, a built in sensor power supply, dual power feeds, and integrated temperature and battery sensors.

A number of new features set this NetGuardian apart from previous versions:

The NetGuardian 832A G4's 8 serial ports can now run up to 110K. This means that you can use your NetGuardian 832A G4 to get data faster, as well as access a larger variety of devices (some modern devices can only run at 110K). The NetGuardian 832A G4 serial ports are RJ45 connectors using the YOST standard, so it's now even easier to connect straight-through or swapover cables.

We've added a secondary NIC, which permits the NetGuardian 832A G4 to connect to two separate networks. In this era of increased security measures and diverse network topologies, an increasing number of deployments require a second network interface. It's important to note, from a security and segmentation point of view, that both LANs can access the NetGuardian 832A G4, but they can't access each other. SNMP Traps, FTP, Web browsing and Telnet can be accessed from either NIC. Each LAN has its own status LEDs to facilitate setup and operation.

In addition to the secondary NIC, the NetGuardian firmware was also enhanced to support SNMP v2. The NetGuardian 832A G4 can still be configured to use SNMP v1 so it will work well in your network, no matter what your Monitoring framework. The NetGuardian SNMP v2 implementation also supports the INFORM command, so SNMP traps can be positively acknowledged from the master. IF the master doesn't acknowledge receipt of the INFORM, the NetGuardian 832A G4 will resend the alarm until the master acknowledges. This is great because it reduces the likelihood of missing an alarm, since the SNMP protocol does not guarantee deliverability.

The NetGuardian 832A G4 also supports a second global SNMP manager, so it's easier than every to support a more secure redundant master architecture.
