Cable types for routers, switches, hubs, and computers

This section lists the types of cables that you require to connect the Sensor to other network devices:

Use a crossover Ethernet RJ-45 cable to connect a router port to computer to the Sensor Management port.

Use a crossover Ethernet RJ-45 cable to connect a computer to the Sensor monitoring port.

Connect the cables for in-line mode

In-line Gigabit Ethernet ports can be congured as fail-open or fail-closed. The RJ-45 monitoring ports are built-in and include an

built-in fail-open functionality as well.

All other monitoring ports require the use of either Trellix's 4-port 1/10 Gigabit Modular Passive Fail-Open kit or external active

fail-open (AFO) kits for In-Line Fail-Open Active conguration.

Gigabit Ethernet ports fail-close, means the ow of trac will stop if the Sensor fails. To allow trac to ow uninterrupted, you

must use special hardware, and cable the Sensor to external active fail-open kits. For instructions, see the subsequent sections of

this chapter.

This section provides the steps to connect the Sensor's Gigabit Ethernet ports so they fail-close.

1. Plug the cable appropriate for use with your transceiver module into one of the Monitoring ports, for example G1/1.

2. Plug the cable appropriate for use with your transceiver module into one of the Monitoring ports, for example G1/2.

3. Connect the other end of each cable to the network devices that you want to monitor.For example, if you plan to monitor

trac between a switch and a router, connect the cable connected to 1 to the switch and the one connected to 2 to the

router.

Connect the cables for tap mode

To deploy the Sensor in tap mode, you must use a Sensor's Gigabit Ethernet Monitoring port pair with a third-party external tap.
