Chapter 4 Troubleshooting Lightweight Access Points

Low Power Condition for Lightweight Access Points

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, one or both readios are deactivated and the Status LED turns amber to indicate low power mode (see Table 4-1).

If your Cisco 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 4-2.

If your inline power source is not able to supply sufficient power for full operation, you should consider these options (see Table 4-2):

•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

Configuring Power Using Controller CLI Commands

Intelligent Power Management support is dependent on the version of software resident in the Cisco switch that is providing power to the access point. Each Cisco switch should be upgraded to support Intelligent Power Management. Until the software is upgraded, you can use your controller to configure the access point to operate with older switch software using these controller CLI commands:

1)config ap power pre-standard enable <ap>

where <ap> is the access point name on the controller

2)config ap power injector enable <ap> <switch port MAC address>

(where <ap> is the access point name on the controller

and <switch port MAC address> is the MAC address of the switch port to which the access point is connected)

Note Refer to your controller documentation for instructions on using these commands.

You can use these controller CLI commands to inform the access point of the following:

•The Cisco switch does not support Intelligent Power Management but should be able to supply sufficient power.

•A power injector is being used to supply sufficient power and the Cisco switch does not support Intelligent Power Management.

Caution If the access point receives power through PoE, the output current of the power sourcing equipment (PSE) cannot exceed 400 mA per port. The power source must comply with IEEE 802.3af or IEC60950 for limited power sources.

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.
