Changes to Dynamic Frequency Selection (DFS) in the 5 GHz Band
Depending on your country/region settings on this product, the available channels in the 5 GHz band
may have changed.
Customers in the U.S.
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
when using this product (zl Module).
This product disables channels 52, 56, 60, 64 (5.25-5.35 GHz) in the U.S. These channels remain available for use
in other countries except as noted below.
Customers in the European Union and Selected Countries/Regions*
In the European Union and selected countries/regions*, ProCurve Wireless Edge Services Modules, Access
Points and Radio Ports purchased after April 1, 2008, are subject to new radar interference requirements that
limit the available channels in the 5 GHz band. To comply with these new requirements, the operating channels
impacted by this change have been removed.
The factory-installed software version that ships with your product limits the available 5 GHz channels to 36,
40, 44 and 48 (5.150 – 5.250 GHz).
* Other countries/regions that apply include South Africa, Turkey, Morocco, Croatia.
