April 8, 2009 online meeting minutes

present: Sergey Boyarinov Sergey Pozdnyakov, Stepan Stepanyan, Ben Raydo, Carlos Salgado

1. LEMO connectors on FADC and DISCR requires corresponding cables from splitters. Splitters will have 'flat' connectors, so we need flat-to-lemo coaxial cable assemblies. We can use the same vendor as for DVCS. Preliminary 7 feet length. Sergey P. will provide old quotation.

2. SY1527 HV connectors: ask CAEN to assemble for us, waiting for possibility and quotation. In a meanwhile, will glue and test one.

3. Discr PRs will be submitted today.

4. DC2 and DC4 were equipped with new power supplies from WIENER. DC1, DC2, DC4, DC10 were added to SNMP-based reset, under testing.

5. Sergey P. testing FASTBUS and Lecroy HV boards; bad 1461N boards which triggered mainframe hungs was finally found. 1881 and 1877 boards under testing.

6. Sergey B. upgraded all Solaris machines (sparc and intel) by recent patches for Solaris 10 update 6. Linux RHEL4 to be upgraded (clon04 already done). New clon01 (intel-based) was installed again, trying to make all processes working.

7. Sergey B. made some improvements in coda_roc, it must be more stable in case of some vxWorks proceses crashed, they will be restarted on 'reset' command rather then 'roc_reboot'. Some infinite loop situations should not happen any more. May consider to check and restart tcpServer as well, and maybe make tcpServer to respond faster.

8. PMC 68-sub switch on SF was connected and configured for 4GBit uplink, have to test and do the same on FC.

9. Need voltage/current readout from snmp-based crates, and restore it for old FASTBUS supplies.

For upcoming run:

• fix HV connectors

• install new cage to clastrig2

• organize new IOC in Pie Tower for Lecroy mainframes

• make sure everything works on new clon01

• look again in 'roc_status' procedure to make sure it shows bad ROC, not infinite dots
