h1isibs crashed again following the power cycled of h1seib2 at 09:07 this morning. EJ took a closer look and found that the problem was most probably with Adnaco A4, which has two BIO cards. h1isibs uses both cards and h1hpibs has no binary IO, which explains why only the ISI model is crashing.

While keeping the IO Chassis powered up, we tried a reboot then a power cycle of h1seib2. No A4 was detected and the adapter card link was red. We then powered the computer down and Erik cleaned the A1 fiber pair. This time the adapter went green and the binary cards were seen again.

We started the models at 15:01 and will run like this overnight. At time of writing, 22:00, it has been running for 7 hours.

WP13475 was opened to move the BIO cards from A4 over to the empty A3 if we need to disconnect A4 from the computer (as has been found for h1lsc0).
