Customers in the U.S. should be aware of FCC Changes to Dynamic Frequency Selection (DFS) in the 5 GHz Band. Effective July 20, 2007, new FCC regulations on the use of the 5GHz band, the band used by radios supporting the IEEE 802.11a standard, prohibit the sale of radios not meeting the new specifications. To comply with these new requirements, several channels in the ProCurve Radio Ports 220 (J9005A), and 230 (J9006A) are disabled by software version WS.01.11 (and later). Software version WS.01.11 (and all versions of WS.02 software) disables channels 52, 56, 60, 64 (5.25-5.35 GHz) in the U.S. These channels remain available for use in other countries. Configurations that have WLANs statically configured to use the 802.11a channels which are disabled after a software update to WS.01.11 or WS.02.xx will find those WLANs returned to default 802.11a settings.
