1Y3 work |

[chub, gautam]
Installation: The following equipment were installed in 1Y3, see Attachment #1:
- Supermicro server, which is the new c1iscaux machine, with IP Address 192.168.113.83.
- 6U Acromag chassis which contains all the ADCs, DACs and BIO units.
- 2 Sorensen DC power supplies to provide +24 V DC and +15 V DC to the Acromags.
- Fusable DIN rail power blocks were installed on the North side of the 1Y3 rack - I placed 2 banks of 5 connectors each for +15 V DC and +24 V DC.
Removal: The following equipment was removed from 1Y3:
- VME crates that were the old c1iscaux and c1iscaux2 machines.
- Spare VME crate that used to be c1susaux, which Chub and I brought over to 1Y3 in an attempt to revive the broken c1iscaux2.
- Approximately 30 twisted ribbon cables that were going to the cross connects. For now, we have not done a full cleanup and they are just piled along the east arm (see Attachment #2), beware if you are walking there!
Software:
- I connected the c1iscaux machine to the martian network.
- Then I edited the relevant files on chiara to free up the IP addresses previously used by c1iscaux (192.168.113.81) and c1iscaux2 (192.168.113.82), and re-assigned the IP address used for c1iscaux to be 192.168.113.83.
- I also changed the hostname of the c1iscaux machine (it was temporarily called c1iscaux3 to allow bench testing).
- I moved the old /cvs/cds/caltech/target/c1iscaux and /cvs/cds/caltech/target/c1iscaux2 directories to /cvs/cds/caltech/target/preAcromag_oldVME/c1iscaux and /cvs/cds/caltech/target/preAcromag_oldVME/c1iscaux2 respectively.
- I moved the temporarily named /cvs/cds/caltech/target/c1iscaux3 directory, from which I was running all the tests, to /cvs/cds/caltech/target/c1iscaux.
- I edited all references to c1iscaux3 in the systemd files so that we can run the approriate systemd services.
Next steps:
- We did not get around to running the DB37 cables between the Acromag chassis and the 1Y2 Eurocrates today - this operation itself took the whole day as we also needed to lay out some support struts etc on the rack to support the Sorensens and the Acromag chassis.
- Once the Acromags are connected to the Eurocrates, we have to run in-situ tests to make sure the appropriate functionality has been restored.
- We must have bumped something in the c1lsc expansion chassis - the CDS FE overview screen is reporting some errors (see Attachment #3). I will fix this.
- General tidiness, strain-relief etc.

I judge that we are good to go ahead with an install tomorrow.
