Switch Software and Documentation Updates  
ProCurve Wireless Edge Services zl Modules and ProCurve Redundant Wireless Services zl Modules support  
ProCurve zl switches (such as 8200zl and 5400zl series) running software version K.12.43 (or later).

Radio Port Bootloader Code Updates for Layer 3 Adoption  
A Wireless Edge Services zl Module (or a Redundant Wireless Services zl 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 the Management and Configuration Guide for the ProCurve  
Wireless Edge Services zl Module and ProCurve Redundant Wireless Services zl Module. See the “Radio Port  
Adoption” section of the manual for more information.  
A Radio Port ships from the factory with a pre-installed bootloader code version. Depending on the software  
version running in a Wireless Edge Services Module and the bootloader code version in the Radio Port, a  
compatible version of bootloader code may be automatically downloaded from the Module to the Radio Port  
when it is adopted.  
Caution  
Bootloader code may be automatically downloaded to the Radio Port whenever a module adopts it.  
DO NOT unplug the Radio Port until it has been adopted or the LEDs indicate an error. Unplugging  
a Radio Port during its adoption may render it unusable.  
Preparing Radio Ports for Layer 3 Adoption  
To support Layer 3 adoption, a Radio Port must have a proper version of bootloader code installed. The zl Module  
will automatically download a proper version during adoption. However, if the current version of bootloader  
code is prior to version 01.00-1918R, the adoption must be done by first adopting the Radio Port in the same  
Layer 2 domain, either by connecting it directly to the Wireless Services-Enabled zl switch, or by connecting it  
to an infrastructure switch in the same Layer 2 domain.  
Note  
The installed bootloader code version may not be easily identified. The version may be obtained prior to Radio  
Port adoption by gathering Radio Port LLDP information while it is connected to a supported switch. However,  
if the bootloader code version cannot be identified, you should adopt the Radio Port in the same Layer 2 domain  
(as described above) to ensure that the proper bootloader code version is installed.
