Chapter 3 Troubleshooting Autonomous Access Points

Low Power Condition for Autonomous Access Points

The access point supports Intelligent Power Management and as a result of the power negotiations, the access point will either enter full power mode or remain in low power mode with the radios disabled.

Note Independent of the power negotiations, the access point hardware also uses the 802.3af classification scheme to indicate the power required from the power source. However, the power source cannot report the power available to the access point unless the power source also supports Intelligent Power Management.

Some Cisco switches that are capable of supplying sufficient power require a software upgrade to support Intelligent Power Management. If the software upgrade is not desired, you can configure the access point to operate in pre-standard compatibility mode and the access point automatically enters full power mode if these Cisco switches are detected in the received CDP ID field.

When the access point determines that sufficient power is not available for full power operation, an error message is logged and the Status LED turns amber to indicate low power mode (see the “Checking the Autonomous Access Point LEDs” section on page 3-2and the “Inline Power Status Messages” section on page 3-7).

Tip If your switch is capable of supplying sufficient power for full operation but the access point remains in low-power mode, your access point or your switch (or both) might be misconfigured (see Table 3-2and Table 3-3).

If your inline power source is not able to supply sufficient power for full operation, you should consider these options:

Upgrade to a higher-powered switch

Use a Cisco Aironet power injector on the switch port

Use the 48-VDC power module to locally power the access point

Inline Power Status Messages

These messages are logged on the console port by the access point to report the power condition:

%CDP_PD-4-POWER_OK: Full Power - AC_ADAPTOR inline power source—This message indicates the access point is using the power module and can support full-power operation.

%CDP_PD-4-POWER_OK: Full Power - NEGOTIATED inline power source—This message indicates the access point is operating at full power and has successfully negotiated for 12.95 W of power from a Cisco switch supporting Cisco Intelligent Power Management.

%CDP_PD-4-POWER_OK: Full Power - HIGH_POWER_CLASSIC inline power source—This message indicates the access point is operating at full power because it has been configured for pre-standard compatibility mode and has detected a Cisco switch that does not support Intelligent Power Management but is able to supply sufficient power to the access point.

%CDP_PD-4-POWER_OK: Full Power - INJECTOR_CONFIGURED_ON_SOURCE inline power source—This message indicates the access point is operating at full power because it is connected to a Cisco switch that supports Intelligent Power Management and the switch has been configured with the power inline never command.

%CDP_PD-4-POWER_OK: Full power - INJECTOR_CONFIGURED_ON_CURRENT_PORT inline power source—This message indicates the access point is operating at full power because it has been configured to expect a power injector on this port.

The access point incorporates advanced technologies such as IEEE 802.11a/g standards, which ensure compatibility with a wide array of wireless clients, ensuring widespread accessibility. The 1130AG also supports Power over Ethernet (PoE), simplifying installation by allowing power and data to be transmitted over a single Ethernet cable. This feature not only streamlines setup but also enhances flexibility, as access points can be installed in locations where power sources are limited.

Security is a paramount concern in wireless networking, and the Cisco 1130AG addresses this through robust security protocols. It supports WPA, WPA2, and other encryption standards, ensuring secure data transmission and protecting against unauthorized access. This is particularly important for organizations that handle sensitive information and require strict compliance with data protection regulations.

Another notable characteristic is the ability of the 1130AG to seamlessly integrate with Cisco's extensive range of network management tools such as Cisco Prime, allowing administrators to monitor and manage their wireless network effectively. This integration provides insights into network performance, user access patterns, and device health, enabling proactive management and troubleshooting.

Moreover, the access point's compact design and durability make it suitable for various deployment scenarios. Designed to withstand varying environmental conditions, the 1130AG can be installed in demanding settings without compromising reliability.

In conclusion, the Cisco Systems 1130AG access point embodies advanced features and technologies that cater to the needs of modern businesses. Its dual-band capabilities, strong security protocols, and ease of management, alongside its durable design, make it an essential component for creating a high-performing wireless network. Whether in office buildings, educational institutions, or hospitality venues, the 1130AG provides the performance and reliability necessary to support today’s connected world.
