Using the DNS for Controller Discovery

Cisco 1000 Series Lightweight Access Point External Power Supply

The Cisco 1000 series lightweight access point can receive power from an external 110-220 VAC- to-48 VDC power supply or from Power over Ethernet equipment.

The external power supply (AIR-PWR-1000) plugs into a secure 110 through 220 VAC electrical outlet. The converter produces the required 48 VDC output for the Cisco 1000 series lightweight access point. The converter output feeds into the side of the Cisco 1000 series lightweight access point through a 48 VDC jack.

Note that the AIR-PWR-1000 external power supply can be ordered with country-specific electrical outlet power cords. Contact Cisco when ordering to receive the correct power cord.

Cisco 1000 Series Lightweight Access Point Mounting Options

Cisco 1000 Series Lightweight Access Point Mounting Options

Refer to the Internal-Antenna AP1010 Cisco 1000 Series IEEE 802.11a/b/g Lightweight Access Point Quick Start Guide or the External-Antenna AP1020 and AP1030 Cisco 1000 Series IEEE 802.11a/b/g Lightweight Access Point Quick Start Guide for the Cisco 1000 series lightweight access point mounting options.

Cisco 1000 Series Lightweight Access Point Physical Security

The side of the Cisco 1000 series lightweight access point housing includes a slot for a Kensington MicroSaver Security Cable. Refer to the Kensington website for more information about their security products, or to the Internal-Antenna AP1010 Cisco 1000 Series IEEE 802.11a/b/g Lightweight Access Point Quick Start Guide or External-Antenna AP1020 and AP1030 Cisco 1000 Series IEEE 802.11a/b/g Lightweight Access Point Quick Start Guide for installation instructions.

Cisco 1000 Series Lightweight Access Point Monitor Mode

The Cisco 1000 series lightweight access points and Cisco Wireless LAN Controllers can perform rogue access point detection and containment while providing regular service. The rogue access point detection is performed across all 801.11 channels, regardless of the Country Code selected.

However, if the administrator would prefer to dedicate specific Cisco 1000 series lightweight access points to rogue access point detection and containment, the Monitor mode should be enabled for individual Cisco 1000 series lightweight access points.

The Monitor function is set for all 802.11 Cisco Radios on a per-access point basis using any of the Cisco Wireless LAN Controller user interfaces.

Using the DNS for Controller Discovery

In Cisco Wireless LAN Solution software releases 3.0 and later, access points can discover controllers through your domain name server (DNS). To use this feature you configure your DNS to return controller IP addresses in response to CISCO-LWAPP-CONTROLLER.localdomain. When an access point receives an IP address and DNS information from a DHCP server, it contacts the DNS to resolve CISCO-LWAPP-CONTROLLER.localdomain. When the DNS sends a list of controller IP addresses, the access point sends discovery requests to the controllers.
