Long-reach multimode adaptor module
Ruckus ICX7150, ICX7250, and ICX7750 Ethernet switches require a long-Reach Multimode (LRM) adaptor module to support LRM optics connections.
The Ruckus LRM adaptor module has two 280 mm Twinax tails and two corresponding SFP+ sockets which operate independently. Power for each of the SFP+ sockets and for the adaptor is provided through the Twinax connections.
The LRM adaptor module requires FastIron software release 08.0.61 or later on the host Ruckus ICX switches. The LRM adaptor module is not field configurable, rather you can apply all configuration to the host switch port. Use the show lrm-adapter ethernet command to display the status of the LRM module.
