Low Power Condition
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
Warning This product must be connected to a Power over Ethernet (PoE) IEEE 802.3af compliant power source or an IEC60950 compliant limited power source. Statement 353
The access point can be powered from the
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
Note An 802.3af compliant switch (Cisco or
Note If your access point is connected to
On power up, the access point is placed into low power mode (both radios are disabled), Cisco IOS software loads and runs, and power negotiation determines if sufficient power is available. If there is sufficient power then the radios are turned on; otherwise, the access point remains in low power mode with the radios disabled to prevent a possible
