Hello Experts. I'm attempting to install an MX450 and the ISP provides a copper RJ45 connection. Unfortunately that's all they offer. The MX450 only has 2 WAN SFP+ ports. The distance between my demarc from my ISP and the rack is roughly 135 feet. Traditionally the equipment supported a Cat6 cable, however with the meraki I'm not sure what I need.

I've tried a copper to SFP transceiver but that only gets the port to flash orange intermittently, every 4-5 seconds. I tried a powered media converter to spit out an SFP cable, however that doesn't light up at all.

Cisco has offered a specific model of transceiver but I'm almost a week out as all local distro's don't have it in stock. Anyone know of a solution here? Any help would be appreciated.

Thanks in advance
