Both of our HMC's have but one lan cable coming out of them (just
physically double checked). They go to the switch. They call IBM when
there is a hardware issue. Actually had a call from IBM about a rack
prior to putting any other cables into it. I can access either HMC
remotely.

Default gateway.
