3900 firmware upgrade

Hi there. I have two Silkworm 3900 switches running FabricOS 5.1.0a. I would like to upgrade to 5.2.x. Is this a seamless upgrade or will my servers lose there connections to the switch that I am upgrading?

Hi Kris, are both switch in the same Fabric ? FabOS upgrade is generally non-distruptive.

Re: 3900 firmware upgrade

When you reboot your switches, you will briefly lose connectivity on those ports. Hopefully you have dual redundant fabrics. If not, you may have issues.
