Low Power Condition for Autonomous Access Points Chapter 3 Troubleshooting Autonomous Access Points 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 appears 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 for Autonomous Access Points 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 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 requires 12.95 W of power. 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 12.95 W. Also, some high-power inline power sources, might not be able to provide 12.95 W of power to all ports at the same time. Note An 802.3af compliant switch (Cisco or non-Cisco) is capable of supplying sufficient power for full operation. Note If your access point is connected to in-line power, do not connect the power module to the access point. Using two power sources on the access point might cause the access point to shut down to protect internal components and might cause the switch to shut down the port to which the access point is connected. If your access point shuts down, you must remove all power and reconnect only a single power source. 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 over-current condition. In low power mode, the access point activates the Status LED low power error indication, displays a low power message on the browser and serial interfaces, and creates an event log entry (see the "Checking the Autonomous Access Point LEDs" section on page 3-2 and "Inline Power Status Messages" section on page 3-7).

Troubleshooting Autonomous Access Points

Low Power Condition for Autonomous Access Points

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 appears 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 for Autonomous Access Points

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 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 requires 12.95 W of power. 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 12.95 W. Also, some high-power inline power sources, might not

be able to provide 12.95 W of power to all ports at the same time.

Note

An 802.3af compliant switch (Cisco or non-Cisco) is capable of supplying sufficient power for full

operation.

Note

If your access point is connected to in-line power, do not connect the power module to the access point.

Using two power sources on the access point might cause the access point to shut down to protect internal

components and might cause the switch to shut down the port to which the access point is connected. If

your access point shuts down, you must remove all power and reconnect only a single power source.

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 over-current condition. In low power mode, the access

point activates the Status LED low power error indication, displays a low power message on the browser

and serial interfaces, and creates an event log entry (see the

“Checking the Autonomous Access Point

LEDs” section on page 3-2

and

“Inline Power Status Messages” section on page 3-7
