I first verified for the IOPs with DACKILLs that their IO Chassis could be seen, which was the case.

I restarted all the models (to clear IOP DACKILLS) on h1oaf0, h1lsc0, h1susb123, h1sush2a, h1sush34, h1sush56. I put all the corresponding SEI IOP SWWD into bypass mode before restarting the SUS IOPs.

All the models restarted with no issues, no reboots (with their associated Dolphin fencing) were needed.

In the morning I'll see if I can find which front end caused the Dolphin crash.

The EDC is slow in reconnecting to susmc3 and susprm channels, but it looks like it will get there in time.
