In my opinion, there is no way to check it with RME.
But i have an idea: maybe (i cant control it at the moment), the OIDs of the installed modules are different (it shold be). If so, you can use an MIB-Browser to find out, wich module has the one OID an wich one the other.
Perhaps, you can create a UNIX-Script, to automate this.
Hope this helps
