    The brains of your environmental monitoring system.
    The AlertWerks ServSensor is the central hub of the AlertWerks environmental monitoring system. Connect it to your network, attach AlertWerks Intelligent Sensors, and you're ready to remotely view the status of your data centers and other facilities. Check for temperature, humidity, and liquids. Know when server cabinet doors are open or closed and whether the cabinet is overheating. Use it for remote monitoring and management of a wide range of devices such as HVAC systems, security equipment, UPSs, generators, and industrial equipment.

    Wide range of sensors.
    The ServSensor features four autosensing RJ-45 ports for connecting any of the AlertWerks Intelligent Sensors in any combination to monitor temperature, humidity, water leakage, airflow, and more. For details, see Related Items.

    Sounds the alarm when things go wrong.
    In addition to enabling you to passively monitor sensors, the AlertWerks ServSensor actively alerts you when sensors exceed limits you determine. It can send alerts via SNMP or by e-mail.

    PoE capability.
    The hub is outfitted with 802.3af PoE, so it can be powered over the Ethernet cable via a PoE injector. This enables you to place it in areas that don't have power outlets.

    Easy installation
    The ServSensor installs in minutes. Simply assign an IP address and connect to the embedded Web server. Plug in any of our AlertWerks Intelligent Sensors and the ServSensor's autosensing feature will recognize the type and automatically configure the sensor. Its embedded Web server enables you to use a standard Web browser to view sensor status over any IP network—even the Internet. Check out the status of your data center from your desk or even while you're on the road.

    Easy management.
    The ServSensor is fully SNMP manageable, so you can integrate it easily into any SNMP-managed network and monitor it through standard SNMP software such as HP® OpenView®. The built-in database maintains a time-stamped log of all events, so you can go back to see what happened and when it happened. The integrated data collection and graphing package is especially useful in spotting trends in security, detection of AC power line voltage, measurement of DC voltage, and control relays, and for providing historical information for analysis.
