suant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses and can radiated ra-
dio frequency energy and, if not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no guarantee that interference will
not occur in a particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user is en-
couraged to try to correct the interference by one of the following measures:
zReorient or relocate the receiving antenna.
zIncrease the separation between the equipment and receiver.
zConnect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
zConsult the dealer or an experienced radio/TV technician for help.
FCC Caution: To assure continued compliance, (example – use only shielded interface cables when
connecting to computer or peripheral devices). Any changes or modifications not expressly approved
by the party responsible for compliance could void the user’s authority to operate this equipment.
This transmitter must not be co-located or operating in conjunction with any other antenna or trans-
mitter.

1. Introduction
1.1. Overview
The IWE1700-A outdoor wireless access point (AP) enables IEEE 802.11b client computers to access
the resources on the Ethernet network. There are 2 model variations, Pro, and Advanced, which are
classified in terms of features. With the sleek Web-based user interface and Windows-based user in-
terface (Wireless Network Manager), a network administrator can easily and clearly manage the AP.
In Chapter 2, we describe the steps to install and configure a newly acquired AP. Following the steps,
the AP can be quickly set up to work. In Chapter 3, detailed explanation of each Web management
page is given for the user to understand how to fine-tune the settings of an AP to meet his or her spe-
cific needs. In addition to using Web-based management user interface to configure an AP, the Win-
dows-based Wireless Network Manager can also be used to configure and monitor deployed APs. See
the on-line help of Wireless Network Manager for more information.
1.2. Features
zIEEE 802.11b
Operational modes
AP/Bridge. This mode provides both Access Point and Static LAN-to-LAN Bridg-
ing functionality. The static LAN-to-LAN bridging function is supported through
Wireless Distribution System (WDS).
AP Client. This mode is for Dynamic LAN-to-LAN Bridging. The AP Client auto-
matically establishes bridge links with APs from any vendors.
64-bit and 128-bit WEP (Wired Equivalent Privacy). For authentication and data
encryption.
Enabling/disabling SSID broadcasts. When the AP is in AP/Bridge mode, the ad-
ministrator can enable or disable the SSID broadcasts functionality for security reasons.
When the SSID broadcasts functionality is disabled, a client computer cannot connect to
the AP with an “any” network name (SSID, Service Set ID); the correct SSID has to be
specified on client computers.
MAC-address-based access control. When the AP is in AP/Bridge mode, it can be
configured to block unauthorized wireless client computers based on MAC (Media Access
Control) addresses. The ACL (Access Control List) can be downloaded from a TFTP
server.
IEEE 802.1x/RADIUS. When the AP is in AP/Bridge mode, it can be configured to au-
thenticate wireless users and distribute encryption keys dynamically by IEEE 802.1x
Port-Based Network Access Control and RADIUS (Remote Authentication Dial-In User
Service).
WPA (Wi-Fi Protected Access). The AP supports the WPA standard proposed by the
Wi-Fi Alliance (http://www.wi-fi.org). Both WPA-PSK (Pre-Shared Key) mode and full
WPA mode are supported. WPA is composed of TKIP (Temporal Key Integrity Protocol)
and IEEE 802.1x and serves as a successor to WEP for better WLAN security.
1

Repeater. When the AP is in AP/Bridge mode, it can communicate with other APs or
wireless bridges via WDS (Wireless Distribution System). Therefore, an AP can wirelessly
forward packets from wireless clients to another AP, and then the later AP forwards the
packets to the Ethernet network.
Antenna alignment assistance.The AP provides a WDS link quality indicator
via Wireless Network Manager to facilitate alignment of directional antennas when
deploying pairs of wireless bridges.
Link health monitoring. This feature enables the administrator to see if the WDS
links of the AP to other peer wireless bridges are working fine.
Wireless client isolation. When the AP is in AP/Bridge mode, wireless-to-wireless
traffic can be blocked so that the wireless clients cannot see each other. This capability can
be used in hotspots applications to prevent wireless hackers from attacking other wireless
users’ computers.
AP load balancing. Several APs can form a load-balancing group. Within a group,
wireless client associations and traffic load can be shared among the APs. This function is
available when the AP is in AP/Bridge mode.
Transmit power control. Transmit power of the AP’s RF module can be adjusted to
change RF coverage of the AP.
Link integrity. When the AP is in AP/Bridge mode and its Ethernet LAN interface is de-
tected to be disconnected from the wired network, all currently associated wireless clients
are disassociated by the AP and no wireless client can associate with it.
Association control. When the AP is in AP/Bridge mode, it can be configured to deny
association requests when it has served too many wireless clients or traffic load is too
heavy.
Associated wireless clients status. When the AP is in AP/Bridge mode, it can show
the status of all wireless clients that are associated with the AP.
Detachable antennas. The factory-mounted antennas can be replaced with high-gain
antennas for different purposes.
zDHCP client. The AP can automatically obtain an IP address from a DHCP server.
zDHCP server. The AP can automatically assign IP addresses to computers or other devices by
DHCP (Dynamic Host Configuration Protocol).
Static DHCP mappings. The administrator can specify static IP address to MAC ad-
dress mappings so that the specified IP addresses are always assigned to the hosts with the
specified MAC addresses.
Showing current DHCP mappings. Showing which IP address is assigned to which
host identified by an MAC address.
zPacket Filtering. The AP provides Layer 2, Layer 3, and Layer 4 filtering capabilities.
zFirmware Tools
Firmware upgrade. The firmware of the AP can be upgraded in the following methods:
2

TFTP-based. Upgrading firmware by TFTP (Trivial File Transfer Protocol).
HTTP-based. Upgrading firmware by HTTP (HeperText Transfer Protocol).
Configuration backup. The configuration settings of the AP can be backed up to a file
via TFTP or HTTP for later restoring.
Configuration reset. Resetting the configuration settings to factory-default values.
zManagement
Windows-based Wireless Network Manager for configuring, monitoring, and diag-
nosing the local computer and neighboring APs. The management protocol is MAC-based.
Web-based Network Manager for configuring and monitoring the AP via a Web
browser. The management protocol is HTTP (HeperText Transfer Protocol)-based.
SNMP. SNMP (Simple Network Management Protocol) MIB I, MIB II, IEEE 802.1d,
IEEE 802.1x, and Private Enterprise MIB are supported.
UPnP. The AP responds to UPnP discovery messages so that a Windows XP user can lo-
cate the AP in My Network Places and use a Web browser to configure it.
Telnet. The user is enabled to manage the AP by Telnet.
System log. For system operational status monitoring.
Local log. System events are logged to the on-board RAM of the AP and can be
viewed using a Web browser.
Remote log by SNMP trap. Systems events are sent in the form of SNMP traps to
a remote SNMP management server.
zPower over Ethernet. Supplying power to an AP over an Ethernet cable using PowerDsine
(http://www.powerdsine.com) technology (IEEE 802.3af compliant in the future). This feature
facilitates large-scale wireless LAN deployment.
zHardware Watchdog Timer. If the firmware gets stuck in an invalid state, the hardware
watchdog timer will detect this situation and restart the AP. This way, the AP can provide con-
tinuous services.
