I worked on preparing for the c1iscaux upgrade a bit today.

1. Attachment #1: This shows where the 120 GB solid-state hard-drive and the 2 RAM cards (2GB each) are installed.
   • I found that it required considerable application of force to get the RAM cards into their slots.
   • Note: the 4GB RAM is broken up into two separate physical cards, each 2GB. The labeling is a bit confusing, as each card suggests it is by itself 4GB.
2. OS install for c1iscaux:
   • I followed Jon's instructions (and added some of mine to the wiki page to hopefully make this process even less thinking-intensive).
   • To be able to use the IP address 192.168.113.83, removed "bscteststand" from chiara martian.hosts and rev.113.168.192.in-addr.arpa as the last mention I could find of this machine was from 2009 (and I'm pretty sure it isn't an active unit anymore). I then restarted the bind9 process. 
   • The hostname for this machine is currently "c1iscaux3" for testing purposes, I will change it once we do the actual install.
   • There was an error in the installation instructions to allow incoming ssh connections - it is openssh-server that is required, not openssh-client. This has now been fixed on the wiki page instructions.
3. Acromag static IP assignment:
   • Assigned 2 ADCs (XT1221), 5 DACs (XT1541) and 5 sinking BIO units (XT1111) static IP addresses (and labelled them for easy reference) using the windows laptop and the Acromag IP config utility.
   • I saw no reason not to use the 192.168.114.yyy scheme for the Acromag subnet on this machine, even though c1auxex and c1vac both have subnets with this addressing prefix. For reasons unknown to me, Jon opted to use 192.168.115.yyy for the c1susaux Acromag subnet.
4. Followed the excellent step-by-step to install EPICS, Modbus and Asyn.
   • This took a while, ~1 hour, dominated by the building of EPICS. The other two took only a couple of minutes each.
   • The same combination suggested on Jon's wiki, of Modbus R2-11, EPICS base-7.0.1 and asyn4-33, are the most current at the time of installation.
   • Couple of typos that prevented straight up copy-pasting were fixed on the wiki.
5. Playground for testing new database files:
   • made a directory /cvs/cds/caltech/target/c1iscaux3 and copied over the .db files from /cvs/cds/caltech/target/c1iscaux and /cvs/cds/caltech/target/c1iscaux2 over.
   • Johannes said he did not develop any code to automate the process of translating the old .db files into the new ones for the Acromag - I won't invest the time in developing any either as I think just manually editing the files will be faster. 
   • I think I will follow the c1susaux convention of grouping .db files by the physical electronics system where possible (e.g. REFL11 channels in one file, CM channels in one file etc), as I think this makes for easier debugging.
   • There is an old "PZT_AI.db" file which I think consists completely of obsolete channels.
6. Next steps:
   • Wire up the crate [Chub]
   • Make the database files and modbus files for talking to the Acromags on the internal subnet [Gautam], check the .db files [Koji]
   • Wiring of whitening switching from P1 to P2 connector, Issue #1 in this elog (this will also requrie the installation of the DIN shrouds) [Koji]
   • Soldering of P2 interface boards [Gautam]
   • Bench testing [Gautam, Koji, Chub]
   • Installation and in-situ testing [Gautam, Koji, Chub]

All the required additional parts should be here by the end of the week - I'd like to aim for Wednesday 7/24 for the installation in 1Y3 and in-situ testing. While talking to Rana, I realized that we should also factor in the c1aux slow channels into this acromag crate - there is no need for a separate machine to handle the shutters and illuminators. But let's not worry about that for now, those channels can simply be added later.
