Introduction
This Altitude 35xx Access Point Product Reference Guide contains setup and advanced configuration
instructions for both the Altitude 3510 and Altitude 3550 model access points. Both the Altitude 3510
and Altitude 3550 model access points share the same Web UI, CLI and MIB interfaces. There are no
differences in how the devices are configured using the instructions within this guide, even though the
Web UI displays Altitude 3510 or Altitude 3550 specifically.
NOTE
Check for the latest versions of documentation on the Extreme Networks documentation website at: http://

However, there are several differences between the two models you should be aware of. The Altitude
3550 is constructed to support outdoor installations, while the Altitude 3510 model is constructed
primarily for indoor deployments. The Altitude 3510 and Altitude 3550 are available in only a dual-
radio SKU—except the Israel SKU which has a single radio. An Altitude 3550 cannot use the Altitude
3510’s 48 volt power supply and, therefore, is recommended to use the Altitude 3550 Power Tap
designed specifically for outdoor deployments. An Altitude 3550 model access point also must use an
RJ-45 to Serial cable to establish a serial connection to a host computer.
The access point (AP) provides a bridge between Ethernet wired LANs or WANs and wireless networks.
It provides connectivity between Ethernet wired networks and radio-equipped mobile units (MUs).
MUs include the full line of terminals, adapters (PC cards, Compact Flash cards and PCI adapters) and
other devices.
The access point provides a maximum 54Mbps data transfer rate via each radio. It monitors Ethernet
traffic and forwards appropriate Ethernet messages to MUs over the network. It also monitors MU
radio traffic and forwards MU packets to the Ethernet LAN.
If you are new to using an access point for managing your network, refer to “Theory of Operations” on
page 28 for an overview on wireless networking fundamentals.
