So I've got some Juniper EX4500's. They're configured as a Virtual Chassis using the SFP+ ports. Due to the distance between racks, I wasn't able to use the VCP ports.
Anyway, I've run into an issue where I'm upgrading the JunOS from 12.3R9-S1 to 15.1R6.7.
It seems that the firmware update happens ok? Maybe? I see no errors that prevent the system from booting.
However, the problem occurs after the system is completely booted. The SFP+ ports used for the VCP connection come up. But the remaining standard network ports do not.
They appear on the system as being disconnected. Or not being connected, on the port indicators, it indicates that the SFP's and cables are connected. But it's still shut down?
I have tried to disable and re-enable the ports, but to no avail. This happens n all ports, whether they have SFP, SFP+ or Copper SFP's.
Is there a step that I am missing from this?
