3e–525C–3 Wireless Access Point Chapter 1: Introduction
29000171-001 A 1
Chapter 1: Introduction
This manual covers the installation and operation of the 3e Technolo-
gies International’s 3e–525C–3 Wireless Access Point. The 3e–525C–3 is
a ruggedized access point/gateway/bridge which is intended for use
in industrial and external environments. It accommodates 802.11a/b/g,
802.11g Super, and 802.11a Turbo WLAN access and uses Power over
Ethernet (PoE) access to the Ethernet WAN to eliminate the need for
internal access point power supply units (AC-DC converters) and 110-
220V cabling installations. The wireless LANs can include mobile devices
such as handheld Personal Data Assistants (PDAs), mobile web pads, and
wireless laptops.
If encryption is desired for the WLAN, you can employ different
encryption depending on the mode you are in. You can select None, Static
WEP, WPA, or WPA2. WPA uses TKIP or AES-CCMP so you can employ
legacy client WEP cards and still secure the wireless band.
The 3e–525C–3 incorporates Power over Ethernet. The PoE interface
on the 3e–525C–3 is compatible with commercial vendor “injected power”
hub units.
The 3e–525C–3 includes cryptographic modules for wireless encryp-
tion and HTTPS/TLS, for secure web communication. In addition, it
contains the capability to use the traditional WEP algorithm, either as
static WEP or managed under WPA. The 3e–525C–3 has an Ethernet
WAN interface for communication to the wired LAN backbone, Ethernet
LAN local port for purposes of initial setup and conguration, and two
wireless AP antennas for communicating on the 802.11a/b/g frequen-
cies. Further, it has the capability for use of an external (remote) antenna,
for bridging, using the 802.11b/g Mixed, 802.11a, 802.11g Super, 802.11a
Turbo frequencies.

Basic Features
The 3e–525C–3 is housed in a sturdy case which is not meant to be
opened except by an authorized technician for maintenance or repair.
If you wish to reset to factory settings, use the reset function available
through the GUI-based management module.
The 3e–525C–3 is wall-mountable.
It has the following features:
• Ethernet uplink WAN port
• Local Ethernet LAN port (for conguration only)
• Wireless VLAN
• Wireless AP with operating range of 2000+ feet
• Wireless Bridge
• Power over Ethernet (PoE)
• Above average temperature range for extreme environments
(with TEC option)
• WEP encryption or WPA/WPA2/AES-CCM with TKIP
• HTTPS/TLS secure Web
• DHCP client
• Adjustable Radio Power
• MAC address ltering
• Load Balancing
• Rogue AP Detection
The following security modules have been implemented in the 3e–
525C–3 .
• WEP
• WPA/WPA2
• AES–CCM
Wireless Basics
Wireless networking uses electromagnetic radio frequency waves to
transmit and receive data. Communication occurs by establishing radio
links between the wireless access point and devices congured to be part
of the WLAN.
