Network Monitoring Signal Tower - Patlite NHL-FB

The NHL has a three-tiered signal tower with a buzzer and E-mail sending capability to report to a network manager immediately when a network event occurs via network connection. This product is the latest version of the Patlite NHM-3/4FB series. The Patlite NH Series tower has configurable LED stack colors and alarms to quickly notify the administrator of network abnormalities. Monitoring is available via SNMP trapping, pinging and user background applications. A test switch operates all tower functions directly for self-diagnosis. Flexible control is possible via socket transmissions and RSH commands. Setup and firmware updating is accomplished by accessing an internal web page and event notification reports can be set up and e-mailed. The simple, ivory-white design ensures this information display blends well with the interior design and surrounding equipment.
