When you issue the command to reset an AP, the AP closesthe SSL connection to the switch before resetting the hardware.To reset one or more APs, click WLAN > Administration > AP Management > Reset.Figure 303: Access Point ResetSelect the APs you want to reset and click Reset, or click Reset All to reset all of the APs managed by the switch.The APs might take several minutes to reset and re-establish communication with the switch. While the AP is resetting, thestatus changes to failed, and then back to managed once the AP is back online.RF MANAGEMENTThe radio frequency (RF) broadcast channel defines the portion of the radio spectrum that the radio on the access point usesfor 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.Each AP is a dual-band system capable of operating in multiple modes. 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 GHzfrequency 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.Interference can occur when multiple access points within range of each other are broadcasting on the same or overlappingchannels. The impact of this interference on network performance can intensify during busy times when a large amount ofThe available channels depends on the country in which the APs operate. The channels described in thissection are valid for the United States.
