Once the Sensor resumes normal operation, the switch returns to the "on" state, once again enabling in-line monitoring. Sensor outage breaks the link connecting the devices on either side of the Sensor for a brief moment and requires the renegotiation of the network link between the two peer devices connected to the Sensor. Depending on the network equipment, this disruption introduced by the renegotiation of the link layer between the two peer devices might range from a couple of seconds to more than a minute with certain vendors' devices. A very brief link disruption might also occur while the links between the Sensor and each of the peer devices are renegotiated to place the Sensor back in in-line mode. This outage, again, varies depending on the device, and can range from a few seconds to more than a minute. You can find the installation and troubleshooting instructions for the kit in the guide that accompanies the kit.
