DESCRIPTION

The Network Power Switch NPS-01 controls AC power to any remote equipment by using simple commands received from a web browser or telnet session through any ethernet network connection. The NPS-01 allows AC powered equipment to be turned on, off, or power cycled from any remote PC, through any network connection. It works well using either a local LAN network or from anywhere in the world using the Internet. Minimal configuration is required, and configuration is via any web browser giving remote network reboot, remote network power control, and remote network watchdog timer control.

The NPS-01 also contains a “Ping Test” watchdog feature for fail-safe AC power control. Using this feature, the unit can issue a periodic PING command to an IP address. If the PING fails (with configurable parameters), the NPS-01 will power cycle the attached equipment. Use this as a fail-safe watchdog power controller for routers, servers, or VOIP/ROIOP devices. The NPS-01 provides status back to the controlling PC so the remote operator knows if power to the controlled device is on or off.

The NPS-01 may be used in conjunction with any device having a web browser (tested using Firefox, Explorer, Chrome, and Safari) or telnet client. The web browser or telnet client may be running on any common PC, MAC, server, iPhone or other smart phone.

The standard model is configured for 120 Volt AC. A 220/240 Volt AC model is available.

Security features allow it to be configured to allow two “control-only” users, who have the ability to turn attached equipment on and off, but not to change configurations, and one “master” user, who can also change the unit’s configuration settings. These user logins may be password protected. In addition, the NPS-01 may be configured to only allow access by workstations having specific IP addresses. Additional security is provided by disabling any two of the three access methods (Web Client, Telnet client, or SNMP manager).

For advanced users, popular PC scripting programs may be used with the controlling PC to provide time-of-day control, automated power switching between remote units, and periodic reboot. This is easily accomplished using common command-line tools such as CURL, or Windows macro-tools (search Google for “workspace Macro recorder shareware” to find an inexpensive program that fits your needs.)
