![Testing the No Break Feature](https://insights.profitap.com/hs-fs/hubfs/Fail-over%20time%20power%20loss.jpg?width=300&name=Fail-over%20time%20power%20loss.jpg)
One of the best ways to get access to your network and see what is happening on a network line is to place a network TAP that gives you full visibility without dropping any packets. However, the last thing you want to happen is that your network goes down in case of an unexpected power failure to the TAP device.
But, there's a big catch here, as the fail-over time can vary greatly depending on the TAP brand. This is an important aspect of this feature, because in the time the TAP switches into its fail-safe mode, packets are lost.

Network TAPs are a must-have when it comes to network monitoring, but there are still some differences between TAP models from different vendors that you need to take into account. One of the things you need to make sure is that the TAP of your choice has the No Break feature to minimize the risk of downtime and ensure complete protection of your network.
