I've purchased the 10G modules and installed them in the 2nd bay of the switches and then inserted the transceivers and interconnected them with crossover fibre patch cord.
The ports never come up there's no activity and status is "detached".
I am dubious regarding the compatibility of sfp+ transceivers I received, they are Intel FTLX8571D3BCV-IT which are 1G/10G capable units. They work fine in 10G mode in one of my PE 720 servers and at 1g in the front of the switch.
Are these Transceivers the correct ones for the job.? If they are, what else can I look at in the switch to diagnose the problem?
Thanks in advance.
