Connecting Data Cables to the AR750S-DP

Connecting the router to your network

1. Connecting to the LAN:
If you have not already done so, use Ethernet patch cables to connect the
devices on your private network (LAN) to the router’s switch ports. By
default, all switch ports are members of VLAN1.
2. Connecting a DMZ:
If you have a public server, use an Ethernet patch cable to connect it to
either:
• one of the router’s Ethernet 10/100 RJ-45 ports, or
• switch ports in a different VLAN than the rest of your LAN
Separating public servers from your LAN allows the firewall to provide
greater protection for your LAN. If you have multiple public servers, you can
connect them to a hub or Layer 2 switch and connect that device to the
router’s DMZ port. For information about configuring VLANs, see the
Switching chapter in the Software Reference.
3. Connecting to the WAN:
Caution If you intend to use a firewall, configure it before you activate the
WAN link.
Once initial configuration is complete, connect the router to the WAN.
Either:
• connect a PIC port to a WAN connection (see the Port Interface Card
Quick Install Guide and Hardware Reference), or
• use an Ethernet patch cable to connect one of the router’s Ethernet
10/100 ports to the Ethernet port of a WAN device (such as a modem).
