Chapter 3 Troubleshooting Autonomous Access Points

Low Power Condition for Autonomous Access Points

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 3-2and “Inline Power Status Messages” section on page 3-7).

Intelligent Power Management

The access point requires 12.95 W of power for full power operation with both radios, but only needs 6.3 W of power when operating in low power mode with both radios disabled. To help avoid an over-current condition with low power sources and to optimize power usage on Cisco switches, Cisco developed Intelligent Power Management, which uses Cisco Discovery Protocol (CDP) to allow powered devices (such as your access point) to negotiate with a Cisco switch for sufficient power.

1130AG specifications

The Cisco Systems 1130AG access point is a robust networking device designed to provide reliable wireless connectivity in a variety of environments. Specifically engineered for both indoor and outdoor applications, the 1130AG is particularly well-suited for use in enterprise, education, and hospitality sectors, where seamless connectivity and coverage are essential.

One of the standout features of the 1130AG is its dual-band operation. It supports both the 2.4 GHz and 5 GHz frequency bands, allowing it to utilize various channels for optimal performance and reduced interference. This dual-band capability enables it to service more devices simultaneously, accommodating the growing demand for wireless connectivity in mobile computing and Internet of Things (IoT) applications.

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.
