    Don’t wait until the day your AC unit fails and your server closet overheats to start protecting your gear. This small, 1RU device alerts you of changing conditions 24 hours a day, 7 days a week, either to your cell or SNMP manager. The NetGuardian 224A is the cost-effective way to stay proactive in your monitoring.
  • Page 6 NetGuardian 224A cannot simultaneously report DCP over LAN and DCP over serial port connection. In addition to its 24 discrete input points, the NetGuardian 224A has 2 control relays, both form C, for user defined NO/NC connections, 2 analogs, and dwire. The control relays allow network administrators to respond remotely to threats to system integrity.
