Chapter 1Introduction
Overview of the AIR-104/204
The AIR-104 and the AIR-204 are small desktop
devices that mediate between your local area network
(LAN) and the Internet. Each AIR-104/204 provides dual
modem connections to access the Internet (the AIR-104
has two external modem ports, while the AIR-204 has
one built-in modem and one external modem port). Your
LAN connects to the AIR-104/204 via a four-port dualspeed Fast Ethernet repeater hub. The AIR-104/204
also features an auxiliary port for a directly connected management console. Data comes in to the
AIR-104/204 from your local network and then is “directed” to the Internet, and vice versa. The AIR104/204 dual-modem design allows connections to either one or two Internet accounts to be
opened and managed automatically.
Figure 1-1
Internet Access with the AIR-104/204
Accessing the Internet
The AIR-104/204 provides shared Internet access, so that everyone on your LAN can surf the web
and send/receive e-mail or files.
The AIR-104/204 utilizes single IP address technology that greatly simplifies the configuration process: the AIR-104/204 automatically acquires the necessary IP addresses when the connection to
the Internet is established, and distributes access to your entire network. You don’t need to apply for
and assign an IP address to each PC or workstation on your network.
The AIR-104/204 features “bandwidth on demand”. Any user’s initial access of an Internet resource
will cause a connection to the Internet to be set up automatically. As the traffic builds up (e.g., more
users try to access the Internet, or the same user generates a lot of traffic), the AIR-104/204 will
automatically establish a second connection through a second Internet account, if one has been
configured. As traffic decreases, one Internet connection will be taken down, until finally, after a configurable period of inactivity, the remaining Internet connection will also be disconnected.

of operation for LAN port 1 is located along the right edge of the router case (see Figure
2-2). Locate the switch and set it to NORMAL mode. Then use an RJ-45 to RJ-45 cable
(not supplied) to connect LAN port 1 to your PC’s Ethernet interface.
Connecting PC’s to the router via a hub or switch
If your network contains more than four PC’s, you will need first to connect the majority of
your PC’s to each other with an external hub or switch, and then connect that hub or
switch to LAN port 1 on the AIR-104/204 (see Figure 2-1). In this configuration, LAN
ports 2,3, and 4 on the AIR-104/204 can still directly connect to PC’s as described
above.
Step 1Connect your PC’s to the external hub or switch. Consult the manufacturer’s
instructions for direction.
Step 2Connect a node port (one that would normally be used to connect a PC
directly) on the external hub or switch to LAN port 1 on the AIR-104/204,
using an RJ-45 to RJ-45 cable (not supplied). Locate the switch that controls
the mode of operation for LAN port 1 on the AIR-104/204, and set it to
UPLINK (this switch is located along the right edge of the router case). See
Figure 2-2. If you are using a special uplink port on the external hub or switch
to connect to LAN port 1 on the AIR-104/204 , then set the mode of
operation for LAN port 1 on the AIR-104/204 to
NORMAL.

Chapter 3 Configuring PC's in the Network
Why do I need to configure PC's?
Any PC that is connected to the network (either plugged directly into the AIR-104/204 or
uplinked from an external hub/switch) requires configuration before it can communicate
with the AIR-104/204.
Each PC must have TCP/IP installed. Additionally, each PC must either be configured to
obtain an IP address through a DHCP server, or must have its IP address set manually.
Only PC’s configured in this manner can share Internet access by means of the AIR-104/
204 .
Note: Any TCP/IP capable workstation can be used to communicate with or through
the AIR-104/204. Other types of workstations may or may not be compatible; please
consult the manufacturer’s documentation.
Note: It is strongly recommended that you configure each network PC to obtain its IP
address automatically from a DHCP server. Only this configuration procedure is escribed
below. If you wish to set network IP addresses manually, please consult more detailed
TCP/IP documentation.
When do I need to configure PC's?
When you first install the AIR-104/204 in your network, you will need to configure a PC so
that you can use it, in turn, to configure the AIR-104/204.
After the AIR-104/204 is properly configured, you will need to configure each PC that is
connected to the network.
What do I need to configure PC's?
For configuration, a PC must have a properly-installed Ethernet or Fast Ethernet network
interface, and that network interface must be connected properly to the network (either
connected directly to a LAN port of the AIR-104/204, or uplinked via a properlyconnected external hub or switch).
There are no operating system requirements for PC’s to be configured. However,
Windows 95 and Windows 98 are the most popular operating systems currently in use;
the procedure described below applies for Windows 95/98. To configure PC’s or
terminals running other operating systems, consult the relevant user manual for
information about installing TCP/IP.
