I am trying to power a SAF Lumina Radio with a CMM4 and having the
following difficulty...
I cannot get the radio to negotiate 1Gbps.
I have made a custom cable that takes an Ethernet cable cabled to the B
standard on both sides with the exception that Pins 4 and 8 are swapped
on one side (solid Blue and Brown). This allows me to power the radio
via the CMM4 and get a 100mbps link. I moved the cable that goes to the
CMM4 switch from the CMM4 from its standard 10/100 port to port 13, a
gigabit port and I still am only able to get 100mbps. Next I took a
Cambium power supply for a PMP430 AP and used my cable connecting
directly to my laptop and still only got a 100mbps link. If I power the
radio with a standard SAF power supply and cable, I do get 1gbps on the
Ethernet link.
Did I cable something wrong causing me not to negotiate to the full
Ethernet link speed?
