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
by software version WS.01.11 (and later).
Software version WS.01.11 (and later) disables channels 52, 56, 60, 64 (5.25-5.35 GHz) in the U.S.
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.
Radio Port Bootloader Code Updates for Layer 3 Adoption
Beginning with software version WS.02.07 (or later), a Wireless Edge Services xl Module (or a Redundant
Wireless Services xl Module) may adopt a ProCurve Radio Port in a different Layer 2 domain if the Radio Port
has a proper bootloader code version installed. This feature, Layer 3 radio port adoption, is discussed in “Radio
Port Adoption” in the Management and Configuration Guide for the ProCurve Wireless Edge Services xl Module
and ProCurve Redundant Wireless Services xl Module. See this section of the manual for more information.
A radio port ships from the factory with a preloaded bootloader code version. Depending on the software version
running in a Wireless Edge Services xl Module and the bootloader code version in the radio port, a different
version of bootloader code may be automatically downloaded from the module to a radio port when it is adopted.
