ICX 7150-48ZP & LRM

I have a number of the 7150-48ZP that we just deployed.  In the past (with another vendor switch) we used LRM SFP+ for connecting wiring closets.  We put in the 7150’s a Ruckus LRM and we are getting a Not Supported when plugged into the SFP ports in the front.  When we plug in an SR we don’t get “Not Supported” message.Are LRM optics not allowed on these switches?
