> I later upgraded to Junos: 18.4R1-S1.1 and then 1 gig sfp's worked, BUT one of them was still not working, and I removed it, so I don't know of there was a vendor sfp that didn't work at all or this one was broken

> I tried to simply configure pic 0 port 0 as 40g and the pic’s stayed offline…even after restarting BOTH pics as is stated as required, they still stay offline… it wasn’t until I configure explicitly all ports, that they finally came online and then port to my upstream device came up also…
