Sensor Hubs
AlertWerks Sensor Hubs provide an intelligent link
between AlertWerks Sensors and your Ethernet network.
The hubs have a built-in Web server, so you can access them
across your IP network with any standard Web browser.
You can also manage the hub through Telnet
™
or any
standard SNMP management software such as HP
®
OpenView®. Hubs also feature a modem port so you can
access them remotely even if your network is down.
When a sensor connected to a hub triggers an alarm, the
hub can e-mail or page you and send SNMP traps to up to ten
locations.
Although the Sensor Hubs require no additional software,
Network Sensor Hub Manager Software (page 4) enables you
to manage multiple hubs from one screen.
The
4-Port Sensor Hub features four ports to connect
external sensors. Two additional serial ports function as a
console server to provide access to network devices’ serial
console ports or for use as a print server. The 4-Port Sensor
Hub has an internal temperature/humidity sensor and is
rackmountable in only 1U of rack space.
2-Port Sensor Hubs are available in a variety of sensor
configurations: temperature, humidity, or temperature plus
humidity. Or choose a 2-port sensor with two serial ports for
access to your network devices’ console ports.
