4.1 AirEZY2405-SWG Installation Overview
AirEZY2405-SWG is designed to be easy and quick to install. The AirEZY2405-SWG has built in
auto-detection features that will auto-detect which application environment it is operating under, this
feature facilitates quick and easy installation.
In order to use your AirEZY2405-SWG wireless LAN, you must have purchased at least two units.
For optimum performance, AirEZY2405-SWG supports up to 6 units within a small work group
configuration (including the unit placed at the file server). (NOTE: If you intend to use the
AirEZY2405-SWG in a network configuration that requires more than 6 wireless nodes, we
highly recommend that you install the AirEZY2405-SWG-Access Point onto your wireless LAN
segment. Please call your OTC Telecom, Inc. sales representative or your authorized reseller
for additional access point information).
The following section describes three (3) standard installation scenarios for your AirEZY2405-SWG
wireless LAN installation:
CASE 1: Client / Server Installation without AirEZY2405-SWG-AP(Access Point)
In order to set up your wireless LAN, one AirEZY2405-SWG unit must be designated as an AirEZY-
Server. This unit automatically configures to become the “access point” on your wireless LAN
segment. The AirEZY-Server unit must be connected directly to a file server, hub , switch, or router on
your LAN segment for the client/server configuration to work properly. The other corresponding units
to be located at your remote PC, laptop, notebook, or printer device, will be configured as AirEZY-
Clients. In a typical office environment, place all the AirEZY2405-SWG units within a 350- 500 feet
radius of the AirEZY-Server unit. When installing your wireless network, be sure to connect and
power on the AirEZY-Server unit first! This step is crucial in allowing the auto-detection features to
be activated properly.

CASE 2: Client / Server Installation using AirEZY2405-SWG-AP(Access Point) For additional
information refer to AirEZY2405-SWG-AP installation manual (included with AirEZY2405-SWG -
AP)
•When using AirEZY2405-SWG with more than six(6) wireless nodes, the AirEZY2405-SWG-
Access Point unit is highly recommended. Install the AirEZY2405-SWG-AP unit adjacent to your
file server or directly onto your hub. Be sure to use the proper UTP cables when connecting the
Access Point to your LAN segment. See Installation Manual for AirEZY2405-SWG-AP for
diagrams
•When using the AirEZY2405-SWG Access Point, be sure to connect and power on the access
point and the AirEZY2405-SWG RF transceiver unit before turning on any other AirEZY2405-
SWG-SWG wireless client units on your remote stations.
NOTE: The yellow LED on your AirEZY2405-SWG RF transceiver unit will exhibit a slow
steady flash pattern.
•Once the Access Point and the RF transceiver units are powered on, you are ready to turn on the
other remote stations. Once you power up the remote stations, the Yellow LED of the RF
transceiver unit and the wireless remote nodes of AirEZY2405-SWG-SWG will exhibit a very rapid
flash pattern.

CASE 3: Peer to Peer Installation
If you are planning to set up a peer to peer work group, instead of placing one AirEZY2405-SWG unit
at the file server, you will need to set it up at your lap top / note book PC, workstation or desktop PC.
For peer to peer application, place one AirEZY2405-SWG unit at your peer desktop or peer laptop PC,
place other AirEZY units at the other designated peer stations. In addition, peer to peer wireless LAN
applications requires Windows 95, Windows NT, Novell Personal NetWare, AppleTalk, or any network
operating system that supports peer to peer connectivity to be properly installed on your system in
advance.
