50 Keysight M9037A PXIe Embedded Controller User GuideUsing the Controller Software Application LicensesSoftware Application LicensesSome software applications require a license to use to the software. For securityreasons the licensing mechanism often uses a composite HostID which dependson several system identifiers. A change to any identifier may result in invalidatingthe licenses on that system. In general, you can retrieve “lost” Keysight softwarelicenses at any time on the Keysight Software Licensing system (ASL) web site atwww.keysight.com/find/softwarelicense. You will need the license order numberand certificate number as well as a valid login and password.If either of the following occurs, verify and possibly reissue the license.- The SSD is re-imaged, replaced, or corrupted.- The controller motherboard is replaced or the primary (system) BIOS serialnumber has changed.For more information, refer to the software application documentation.Using Multiple SSD in a single M9037AThe SSD is mounted on a carrier that can easily be inserted or removed from theM9037A (see “Replacing the SSD” on page 69). For some working environments, itis very convenient to use multiple SSD so that you can make changes to one SSDwithout disturbing the other. This is convenient when multiple people are using thesame M9037A and they do not want to interfere with the other person’s project. It isalso convenient when one person is supporting the M9037A as deployed to thefactory floor, while developing new code for later deployment. From Keysight, youcan purchase additional SSD with carrier and with a windows operating system (see“M9037A Accessories” on page 23). Alternatively, you can buy a new SSD from a 3 rdparty, copy your old SSD to the new SSD, install it in your carrier, and insert it intoyour M9037A.DriversAll of the M9037A Controller and chassis drivers were installed on your controllerat the factory. You should not need to reinstall them. However, you shouldperiodically check the M9037A web page (www.keysight.com/find/M9037A) forupdated drivers.For the IVI driver, help file, program examples, etc. go to the following SSDfolder:C:\Program Files\IVI Foundation\IVI\Drivers\AgPxiPc
