2.2.3

Connect to Local Application Servers

Connect a local application server such as a web, e-mail, video, gaming, building automation, etc. to port 15
(reserved by default) of the integrated Ethernet switch. If you wish to connect more than one local application
server, then either hook them up with an external Ethernet switch and connect its uplink port to port 15 or to port 1
to 14, but remember to make that port visible to the entire switch (see next).
2.2.4

Connect the VLAN Configuration Port

In case you need to change the default Virtual LAN (VLAN) configuration of the integrated Ethernet switch, use a
terminal emulator on a computer and connect it to the VLAN CONF. port. Connect the RJ-11 connector end of the
supplied cable to the VLAN CONF. port of the switch and the 9-pin end to a serial port (COM1, COM2 or other
COM port) of your computer.
Please exercise caution when changing the default switch VLAN configuration as there may be security
Virtual LANs (VLANs)
VLAN stands for Virtual Local Area Network. It partitions a physical network into multiple virtual, or logical,
networks. The stations on a logical network belong to one group; however, a station can belong to more than one
group. With VLAN, a station cannot directly talk to or hear from stations that are not in the same group(s); the
traffic must first go through a router. This isolates the subscribers from one another and prevents a subscriber from
discovering the resources, e.g., shared drives or printers, of another subscriber. The Prestige factory default is that
ports 1 to 14 of the integrated switch are in their own individual groups (networks) and ports 15 and 16 belong to
all groups.
VLAN also increases network performance by containing broadcasts to a smaller and more manageable logical
broadcast domain. In traditional switched environments, all broadcast packets go to each and every individual port.
With VLAN implemented, all broadcasts are confined to a specific broadcast domain.
