FX-16NW

Note :

Be sure to match ports in a Trunk in increasing order.

Example :

Port 1 through 4 in Trunk 1 of Hub A need to be linked to ports with the

same number in Trunk 1 of Hub B.

Hub A Trunk 1 (Port 1,2,3,4) <-> Hub B Trunk 1 (Port 1,2,3,4)

—> Matching order: 1-1, 2-2, 3-3, 4-4

Note:

Even though four ports are assigned to a trunk, only some of them may be

actually in use if less than four devices are attached to the Switch. For

instance, only two out of the four ports will be used if Hub A and Hub B in

the example above has only one device attached.

When Port Mirroring feature of the Switching Hub is enabled, the traffic on

a given port is copied to another port that is attached to a LAN analyzer or

similar device.

For instance, a traffic between Port 1 and Port 2 on a traditional switch does

not basically flow to another port. For this reason, both a LAN analyzer and

devices such as repeater hubs are required to inspect the traffic between the

two ports. With FX-16NW, the extra devices are no longer required.

Simply enable the Port Mirroring feature and attach a LAN analyzer such as

S n i ffer to the destination port- you can analyze the traffic without using

other devices, swiftly narrowing down the scope of possible causes of port

malfunction.

Port Mirroring

By bundling four ports into one high-throughput trunk, the Tr u n k i n g

technology allows two units of FX-16NW to communicate at 800Mbps

maximum (full-duplex 200Mbps x 4). The high-throughput trunk(s) can

boost the data transfer speed between hubs in a cascade connection.

For a specific procedure to configure the Trunking function, please refer to

Chapter 3.

※The Switching Hub only supports a trunking connection with antoher FX-

16NW; it cannot be trunked to other devices with Trunking support.

The Switching Hub supports three types of Trunk settings. To connect two

FX-16NWs via a trunk, both units need to be configured in the same

manner.
