Introduction
Introduction
A Cisco Aironet Access Point is a wireless LAN transceiver that can act as the connection point between
wireless and wired networks or as the center point of a standalone wireless network. Cisco Aironet
Bridges are wireless LAN transceivers that connect two or more remote networks into a single LAN.
The access point and bridge use a browser-based management system. The system settings are on web
pages in the system firmware. You use your Internet browser to view and adjust the system settings.
Installation Notes
You can find the latest release of access point and bridge firmware at this URL:
http://www.cisco.com/public/sw-center/sw-wireless.shtml
Installation in Environmental Air Space
Cisco Aironet 350 Series Bridges and metal-case access points are suitable for use in environmental air
space in accordance with Section 300-22(c) of the National Electrical Code.
Caution The Cisco Aironet Power Injector has a smaller operating temperature range (32 to 104
than the 350 series bridge and metal-case access point. The power injector is not intended for use in
extremely high or low temperatures or in environmental air spaces, such as above suspended ceilings.
Antenna Installation
For instructions on the proper installation and grounding of external antennas, refer to the National Fire
Protection Association’s NFPA 70, National Electrical Code, Article 810, and the Canadian Standards
Association’s Canadian Electrical Code, Section 54.
Warning
Do not locate the antenna near overhead power lines or other electric light or power circuits, or
where it can come into contact with such circuits. When installing the antenna, take extreme care
not to come into contact with such circuits, as they may cause serious injury or death.
Power Considerations
Caution The operational voltage range for 350 series access points and bridges is 24 to 60 VDC, and the nominal
voltage is 48 VDC. Voltage higher than 60 VDC can damage the equipment.
o
F; 0 to 40oC)
Caution Cisco Aironet power injectors are designed for use with 350 series access points and 350 series bridges
only. Do not use the power injector with any other Ethernet-ready device. Using the power injector with
other Ethernet-ready devices can damage the equipment.

Updating Firmware
3. Follow this link to the Software Center on Cisco.com and download firmware version 12.01T1:
http://www.cisco.com/public/sw-center/sw-wireless.shtml
Note To upgrade firmware from a file server, you must enter settings on the access point’s or bridge’s FTP
Server Setup page. Refer to chapter 6 in the Cisco Aironet Access Point Software Configuration Guide
for more information.
Limitations and Restrictions
This section describes limitations and restrictions for 340 and 350 series access points and 350 series
bridges.

Limitations and Restrictions
Cisco Aironet 350 Series Bridges Incompatible with 340 Series Bridges
Cisco Aironet 340 and 350 Series Bridges can be connected to the same LAN segments, but they cannot
communicate wirelessly. Although you can disable STP on non-root 350 series bridges, 350 and 340
series bridges are not designed to interoperate. If you use both 340 and 350 series bridges on your
network, make sure the 340 series bridges have radio bridge links only to other 340 series bridges, and
that 350 series bridges have radio bridge links only to other 350 series bridges.
Removing Power During Firmware Update Can Corrupt Radio Firmware
When you update the firmware on an access point or bridge, allow the unit to finish its start-up sequence
before removing power. If you update the firmware and remove power before the unit finishes the
start-up sequence, the radio firmware might be corrupted, making the unit inoperable. If the radio
firmware is corrupted, the radio indicator (the bottom of the three indicators on top of the access point
or bridge) lights steady red, and the following error message appears when the access point or bridge
starts up:
Failed to start driver for port “awc0” (errno=0x006d0002)
If the radio firmware is corrupted, you should try to reset the unit to factory defaults using the :resetall
command in the CLI; see chapter 9 of the Cisco Aironet Access Point Software Configuration Guide for
instructions on resetting the access point. If the unit cannot be reset to defaults, you must return the unit
to Cisco for service.
You can safely remove power after a firmware update when the configuration management pages
reappear in the command-line or web-browser interfaces, or when the three status indicators on top of
the unit complete the following pattern:
1. All three indicators are steady green, meaning that the access point is beginning to update the
firmware.
2. The middle indicator is steady green and the top and bottom indicators are off, indicating that the
access point or bridge is updating the radio firmware.
When the middle indicator blinks or the top and bottom indicators blink, you can remove power.
EAP Authentication Requires Matching 802.1x Protocol Drafts
Note This section applies to wireless networks set up to use LEAP. If you do not use LEAP on your wireless
network, you can skip this section.
Wireless client devices use Extensible Authentication Protocol (EAP) to log onto a network and generate
a dynamic, client-specific WEP key for the current logon session. If your wireless network uses WEP
without EAP, client devices use the static WEP keys entered in the Aironet Client Utilities.
If you use Network-EAP authentication on your wireless network, your client devices and access points
must use the same 802.1x protocol draft. For example, if the radio firmware on the client devices that
will associate with an access point is 4.16, the access point should be configured to use Draft 8 of the

through 12.01T
Note Draft standard 8 is the default setting in firmware version 11.05 and earlier, and it might remain in effect
when you upgrade the firmware to version 11.06 or later. Check the setting on the Authenticator
Configuration page in the management system to make sure the best draft standard for your network is
selected.
Use the Authenticator Configuration page in firmware version 11.06 or later to select the draft of the
802.1x protocol the access point or bridge radio should use. Follow these steps to set the draft for your
access point or bridge:
Step 1 Browse to the Authenticator Configuration page in the access point management system:
a. On the Summary Status page, click Setup.
b. On the Setup page, click Security.
c. On the Security Setup page, click Authentication Server.
Step 2 Use the 802.1x Protocol Version (for EAP authentication) pull-down menu to select the draft of the
802.1x protocol the access point or bridge radio should use. Menu options include:
• Draft 7—No radio firmware versions compliant with Draft 7 have LEAP capability, so you
should not need to select this setting.
• Draft 8—Select this option if LEAP-enabled client devices that associate with this access point
or bridge use radio firmware versions 4.13, 4.16, or 4.23.
