Remote Connections With Fiber Cable; Making Vlan Connections - AMX NXA-ENET8-2POE Instruction Manual

Remote Connections with Fiber Cable

Fiber optic technology allows for longer cabling than any other media type. A 1000BASE-SX (MMF) link can connect to a site up to
550 meters away, a 1000BASE-LX (SMF) link up to 10 km, a 1000BASE-LH link up to 80 km, and a 100BASE-FX (SMF) link up to 20
km. This allows the switches to serve as a collapsed backbone, providing direct connectivity for a widespread LAN. FIG. 12
illustrates the NXA-ENET8-2POE connecting multiple segments with fiber cable.

Making VLAN Connections

The NXA-ENET8-2POE supports VLANs which can be used to organize any group of network nodes into separate broadcast
domains. VLANs confine broadcast traffic to the originating group, and can eliminate broadcast storms in large networks. This
provides a more secure and cleaner network environment. VLANs can be based on untagged port groups, or traffic can be explicitly
tagged to identify the VLAN group to which it belongs.
Untagged VLANs can be used for small networks attached to a single switch. However, tagged VLANs should be used for larger
networks, and all the VLANs assigned to the inter-switch links.

NOTE: When connecting to a switch that does not support IEEE 802.1Q VLAN tags, use untagged ports.
