Configuring the ProCurve Wireless Edge Services zl Module

Software Images

The Wireless Edge Services zl Module maintains two software images:

■ primary

■ secondary

Typically, the primary image loads when the Wireless Edge Services zl Module is

rebooted. However, you can configure the module to reboot with either the primary

or the secondary image.

The two images provide failover capabilities in the event that one software image

becomes corrupted. If a software image fails to initialize completely during two

consecutive reboots, the Wireless Edge Services zl Module automatically boots with

the other image.

Having two images also simplifies the update process. For example, you can boot

the Wireless Edge Services zl Module with the secondary image and then update the

primary image. Likewise, you can boot the module with the primary image and update

the secondary image. After you upgrade the software and reboot the module, the

module, by default, loads the upgraded image.

ProCurve Networking uses the following naming convention for software image

files:

WT.xx.yy

The xx is replaced with numbers that indicate a major release of the software image.

The yy is replaced with numbers that indicate a minor release of the software.
