NXA-ENET8POE Gigabit PoE Ethernet Switch

Meeting Room

With eight 1000 Mbps parallel bridging ports (i.e., eight distinct collision domains), the NXA-ENET8POE can

function as an efficient bridged node that is ideal for a meeting room environment. Zero noise makes the

switch unobtrusive for such a setting.

In FIG. 4, the ES4308-PoE is connected to a central wiring closet via a 1000BASE-SX connection. The

1000BASE-T RJ-45 ports on the switch are providing 10/100 Mbps full-duplex connections for PCs and

notebooks, as well as providing power and connectivity for PoE devices, such as IP telephones and web

cameras.

Making VLAN Connections

The NXA-ENET8POE supports VLANs that can be used to organize any group of network nodes into separate

broadcast domains (FIG. 5). 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.
