4 Attaching cables to the Sensor About the fail-open hardware continues to flow through the network link, but is no longer routed through the Sensor. Once the Sensor resumes normal operation, the switch returns to the "on" state, once again enabling in-line monitoring. Note that 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 may range from a couple of seconds to more than a minute with certain vendors' devices. A very brief link disruption may 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. Installation and troubleshooting instructions for the Kit can be found in the Guide that accompanies the kit. For example, for more information on the Optical kit, see the standard Gigabit Optical Fail-Open Bypass Kit Guide. N-450 Sensor also supports Active Bypass Kit. 28 McAfee® Network Security Platform M-2750 Sensor Product Guide
