Configuration Guide Configuration Settings Xirrus Arrays initially boot with all radios disabled except for the monitor radio. The monitor radio may be left enabled and in no way interferes with the SpectraLink Wireless Telephones; however it was disabled for the certification process for simplicity. Disabling the monitor radio If you wish to disable the monitor radio, use the following CLI commands: Xirrus_WLAN_Array# configure Xirrus_WLAN_Array(config)# interface iap Xirrus_WLAN

Configuration Guide Setting Radio Channels With the SpectraLink Wireless Telephones operating in 802.11b mode, at least one of the Wireless LAN Array’s Integrated Access Points (IAPs) must be set to the 2.4 GHz band. Any of the Array’s four abg radios may be used, and up to three may be used simultaneously. However, the radios must be set to the non-overlapping channels 1, 6, and 11. This may be done using the following CLI commands: Xirrus_WLAN_Array# configure Xirrus_WLAN_Array(con

Xirrus Wi-Fi Array: XS-3500/3700/3900 Setting Radio Cell Size The radio transmit powers and receive sensitivities should be set appropriately for the environment in which they are operating. The simplest way to do this is to pick an operating cell size for them. The following CLI commands illustrate how to set a small cell size on three of the abg radios. Please see the Xirrus Wi-Fi Array Users Guide for a detailed explanation of radio transmit power, receive sensitivities and cell

Xirrus Wi-Fi Array: XS-3500/3700/3900 The global encryption cipher for WPA2-PSK can also be set through the WMI as illustrated in Figure 4 Global WPA Settings. The difference between the WPA-PSK and WPA2-PSK settings is that, for WPA2- PSK, No should be selected on the TKIP Enabled line, and Yes should be selected on the AES Enabled line. Similarly, the SSID specific settings for WPA2-PSK may be applied as shown in Figure 5 SSID Specific WPA Settings. For Security Type select WPA2 inst
