Long-Reach Multimode Adapter Module

All ICX 7550 models support LRM optics through the ICX7650-4x10G module. Downlink ports on ICX 7550-24F and ICX 7550-48F require LRM adapter modules to support LRM optic transceivers.

The RUCKUS LRM adapter 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 adapter is provided through the Twinax connections.

The LRM adapter 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 adapter module.
