Overview | IP Controlled Power Strip

WebSwitch™ Remote Power Switch, is the ideal IP controlled power strip for remote power control, remote reboot, and automatic reboot of network devices using a standard web-browser.

WebSwitch Remote Power Switch with cords

Two, Independent IP Controlled Power Outlets

WebSwitch has two power outlets which can be independently controlled over an IP network using a web browser on a computer or smartphone. It is completely self-contained and includes a built-in web server, so no external servers, or monthly subscriptions are required.

Remote Power Control

Use WebSwitch as a remote control outlet that provides remote power control and/or automatic reboot of these devices: Servers, computers, routers, and other electrical devices.

Automatic Reboot & Remote Reboot Device

When configured for automatic reboot, WebSwitch will periodically ping a designated IP address and wait for a response. If there is no response to the ping, WebSwitch will automatically reboot the powered device in an attempt to restore its normal operation.

If automatic reboot isn’t configured, manual remote reboot can easily be achieved by a simple press of a button on the device’s Control Page.

WebSwitch is available in two models, WebSwitch & WebSwitch Plus!

WebSwitch Plus™
