WEP Keys

The WEP key you use to transmit data must be set up exactly the same on your access point and any
wireless devices with which it associates. For example, if you set WEP Key 3 on your client adapter to
0987654321 and select it as the transmit key, you must also set WEP Key 3 on the access point to exactly
the same value. The access point does not need to use Key 3 as its transmit key, however.
Refer to the Cisco IOS Software Configuration Guide for Cisco Aironet Access Points for instructions
on setting the access point's WEP keys.

Security Settings

Wireless clients attempting to authenticate with your access point must support the same security options
configured in the access point, such as EAP or LEAP, MAC address authentication, Message Integrity
Check (MIC), WEP key hashing, and 802.1X protocol versions.
If a wireless client is unable to authenticate with your access point, contact the system administrator for
proper security settings in the client adapter and for the client adapter driver and firmware versions that
are compatible with the access point settings.
Note
The access point MAC address that displays on the Status page in the Aironet Client Utility (ACU) is
the MAC address for the access point radio. The MAC address for the access point Ethernet port is
printed on the label on the back of the access point.

Low Power Condition

This product must be connected to a Power over Ethernet (PoE) IEEE 802.3af compliant power source
Warning
or an IEC60950 compliant limited power source. Statement 353
The access point can be powered from the 48-VDC power module or from an in-line power source. The
access point supports the IEEE 802.3af power standard, Cisco Pre-Standard PoE protocol, and Cisco
Intelligent Power Management for in-line power sources.
For full operation, the access point (powered device) requires 12.95 W (up to 15.4 W with 100 m
CAT 5 Ethernet cable). When the access point is being used in a PoE configuration, the power drawn
from the power sourcing equipment (PSE), such as a switch or power injector, is higher by an amount
dependent on the length of the interconnecting cable.
The power module and Cisco Aironet power injectors are capable of supplying the required power for
full operation, but some inline power sources are not capable of supplying sufficient power. Also, some
high-power inline power sources, might not be able to provide up to 15.4 W of power to all ports at the
same time.
An 802.3af compliant switch (Cisco or non-Cisco) is capable of supplying sufficient power for full
Note
operation.
