h1sush6 front end computer first boot

Fil, Erik, Dave:

Fil ran the 24V-DC power to the h1sush6 IO Chassis on the MER Wed afternoon and I completed the fiber connections to the rear of the computer in the MSR. Erik and I booted h1sush6 for the first time late Wed afternoon after setting the BIOS and IPMI.

Current hardware status:

computer has Dolphin card installed but not connected to the switch. MTP at the computer end sends 4-Adnaco and 1-timing pairs to the MER via port-3 on the patch.

This is a W2275 14core machine, was cdsproxmox2. Its disks have been removed and it needed a full set of RT BIOS changes.

IO Chassis is "what was left" of h1sush2b after cards were moved over to the new h1sush12 chassis. So it has a mismatch of cards, but each Adnaco has a unique layout which is all that is needed to confirm Adnaco functionality.

A1 [slot1=TC, slot4=18AO8]

A2 [slot1=18AO8,slot2=16AO16]

A3 []

A4 [slot1=BIO]

The computer booted with some difficulty because it was trying to load the non-existent h1iopsush6 model. We were finally able to ssh onto the machine and showcards sees all the cards except A4. 

Also the timing card is not syncing, we will investigate that today.

A minor issue, we had some DNS issues on the workstation-LAN which Erik resolved.
