Page 5: Netguardian 224A Overview
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.
