• Factory Reset All—Factory resets all managed APs listed on the page.
• Reset All—Resets all managed APs listed on the page.
• Refresh—Updates the page with the latest information.
The APs might take several minutes to reset and re-establish communication with the switch. While the AP is
resetting, the status changes to failed, and then back to managed once the AP is back online.

RF Management

The radio frequency (RF) broadcast channel defines the portion of the radio spectrum that the radio on the
access point uses for transmitting and receiving. The range of available channels for an access point is
determined by the IEEE 802.11 mode (also referred to as band) of the access point.
The DWL-8600AP and DWL-6600AP are dual-band systems capable of operating in the 2.4 GHz and 5 GHz
frequencies. The DWL-3600 is a single-band system and operates in the 2.4 GHz frequency. Multiple operating
modes are available within each frequency. Configuration options for the IEEE 802.11a/n (5 GHz) modes do
not apply to the DWL-3600AP.
IEEE 802.11b and 802.11g modes (802.11 b/g) operate in the 2.4-GHz RF frequency and support use of
channels 1 through 11. IEEE 802.11a mode operates in the 5 GHz frequency and supports a larger set of non-
consecutive channels (36,40,44, 48, 52, 56, 60, 64, 149, 153, 157, 161, 165). IEEE 802.11n mode can operate
in either the 2.4 GHz or 5 GHz frequency.
Note: The available channels depends on the country in which the APs operate. The channels
described in this section are valid for the United States.
Interference can occur when multiple access points within range of each other are broadcasting on the same
or overlapping channels. The impact of this interference on network performance can intensify during busy
times when a large amount of data and media traffic is competing for bandwidth. For the b/g radio band, the
classical set of non-interfering channels is 1, 6, 11. Channels 1, 4, 8, 11 produce minimal overlap. A similar set
of non-interfering channels is used for the a radio band, which includes all channels for that mode since they
are not overlapping.

Configuring Channel Plan and Power Settings

The DWS-4000 Series switch software contains a channel plan algorithm that automatically determines which
RF channels each AP should use to minimize RF interference. When you enable the channel plan algorithm, the
switch periodically evaluates the operational channel on every AP it manages and changes the channel if the
current channel is noisy.
Note: The regulation of radio frequencies and channel assignments varies from country to country. In
countries that do not support channels 1, 6, and 11 on the 802.11b/g/n radio, the channel plan
algorithm is inactive. For the 5-GHz radio, the algorithm is inactive in countries that require 802.11h
radar detection, which includes European countries and Japan.
