CRS354-48P-4S+2Q+RM Bad "asic"?

I have a switch that all ports in an 8 block of ports (9-16) will not transmit nor receive. This occurred recently after the switch powered back on from a power outage. I haven’t had the opportunity to reboot the switch; anyone had this happen to their switches?

Today I upgraded all of my on-site switching (Layer 2) to 7.17.1. This “fixed” the ASIC issue - with ports 9 through 16 working perfectly now. A reboot might have sufficed, but I took the opportunity to do an emergency upgrade.
