Richard, Corey, Dave:
I disabled Dolphin EY port 4, Richard moved the RFM cable from port 4 to port 5 and we now have IPC traffic in both directions to EY.
CDS overview is now all GREEN, looks like our recovery from h1boot1 crash is complete.
I've modified the configuration file on h1boot1 (/diskless/root/etc/ixnodetab) to move h1cdsrfm Y0 to port 5.
h1susey Y0 1
h1seiey Y0 2
h1iscey Y0 3
h1cdsrfm Y0 5 002353
The end-station problem is horribly like the problems we had at LLO last week replacing l1iscex - see LLO log 48295. Again one port on the switch would not respond to port enable/disable commands. As you did, we just moved it to another port. We tried using the 'RESET' command on the web interface (suggested by the vendor previously), but that was insufficient. It may requires a power cycle after the reset, but it is unclear. I am elevating this issue with the vendor to get a resolution.
