LoadMaster firmware; 32 or 64-bit

Different LoadMasters require different firmware to operate properly. Some units will work with a 32-bit patch, meanwhile other units will only work with a 64-bit patch. The firmware version of the unit to be upgraded will determine which patch architect to choose. Refer to the lists below to find out what firmware versions apply to what units.

The LoadMaster operating system (LMOS) transitioned to 64bit only with the availability of the 7.2.36 release (November 2016) . 32bit platforms are supported with the LTS (Long Term Stable) release which is maintained to include vulnerability mitigation's and bug fixes
