Hi Community, I have a frustrating issue at on offsite data center: Did a firmware upgrade on my switches from 17.1.3 to 17.2.1.1 and after the reboot my Cohesity cluster has two nodes that are not getting link. I've tried rolling back the firmware and then when that didnt work I reinstated it. Called Meraki support and they recommended we go on site, try other cables and swap them around. I have a handful of these cables and not a single one worked. I did however get link when I connected the non-working nodes to the two SFP ports that were up. That of course led me back to the switch. I have 8 available ports on two different switches and non will accept the connection. What gives! I also overnighted two new DAC cables from FS with luck. Meraki of course is recommending their approved cables via the documentation. Anyone else have these challenges. They have been working for 2 years, and I have 4 working with no issues at another datacenter. Cohesity does not care what cables you use. In fact, they have no guidelines telling you what to use. I spent two hours on a call with them, and they said t was nothing on their hosts. I would greatly appreciate some guidance. Is the next step to buy Meraki certified SFP modules? They don't exactly have recommended DAC cables. I would love to know if others have had issues like this with Meraki switches. Here are the cables we have: Amazon.com: 10Gtek 10G SFP+ DAC Cable - 10GBASE-CU Passive Direct Attach Copper Twinax SFP Cable for Cisco SFP-H10GB-CU3M, Meraki MA-CBL-TA-3M, Ubiquiti UniFi, Netgear, Fortinet, 3-Meter(10ft), 4-Pack : Electronics FS: https://www.fs.com/products/30862.html?attribute=8722&id=2354432
