Please do not forget to check the software version running on your Aruba 2930M (JL319A): to support the JL083A Module the Aruba 2930M needs to run a Software version equal or newer than WC.16.04.0004, as example WC.16.04.0016 to be safe (indeed if your Aruba 2930M is running a software version that is older than WC.16.04.0004 - this considering releases belonging to the WC.16.03 code branch since the WC.16.04.0004 is the very first of WC.16.04 derived from WC.16.03 - just update to latest WC.16.04.0016 available...otherwise, if you prefer to upgrade from WC.16.04 or older to newer code branches such as WC.16.05 or WC.16.06, just plan to upgrade your Aruba 2930M to latest WC.16.05.0009 or latest WC.16.06.0006).
