ATTENDEES

Diane, Kukhee, Sonya, Kristi, Terri, Ernest, Sheng 

TOPICS: Installation

Need to know-

1)      the scope of the installation effort for each subsystem.

...

**- we will install this new switch swh-li21-nw01, move these iocs from swh-in20-nw02 to this switch

...

• install all new fiber and new switches, leave old private switches in place for RF, BPMs, BLENs
• configure new switches for all BPMs, BLENs, RFEIOs RF EIOCs (set the EIOC ports to receive only multicast from their master IOC)
• THEN, for every IOC and EIOC involved in feedback,
  • test the new network connections by moving network cables to new switch and ping (add a couple lines in start-up file)
  • this will likely take several days and will involve both Network group and each subsystem engineer (Kristi, Sonya, Sheng, Kukhee)
  • when done testing an IOC / EIOC move connections BACK TO ORIGINAL SETUP. We must leave the system in its original state for start-up in April
  • QUESTION - do we need to disconnect the magnet IOCs, and UND BPM IOCs 2nd NIC when done testing? Definitely not the Controller IOCs.
• Terri will determine the overall schedule for this work, with input from Kristi, Sonya, Sheng, and Kukhee
  

 NOTE: Once beam is back up in April, the subsystems that now use private switches (RF, BPM, BLEN) will need to move cables from private switches to new FCOM switches when installing new software in production. Backout will include moving cables back.

Magnets

This involves two Magnet IOCs.  The new magnet sofware must be a single image that works in IOCs that control the new fast correctors, and IOCs that do not.

...

Before April the network connections/switch configurations will have been tested as described above. After start-up we must schedule time for the following installation plan:

• BLENs
  On
  • One MD day to install and test both BLEN
  IOCs
  • IOCs - let them run if it checks out ok
  • NIC 2 cabling must be switched from private switch to the new FCOM network switch at the same time the software is installed.
  • BPMs
    • Sonya, Till - I did not write down a specific plan for the BPM IOCs. Do you expect to need a couple weeks of check-out time, similar to Kristi's plan above? Please let me know what's required after start-up.

  Controller IOCs

  3 controller IOCs.  We should be able to install the Controller IOCs during the downtime, or really anytime before April. They may be useful for production network testing during the downtime (we could run Till's tests in production maybe?) - Terri and Ernest can plan to install the Controller IOCs with the network installations. 

  ...

  • one MD day, plus coordinate with photon group,  to install version 2 BLD and test.
    

  RF IOCs

  We did not get to this topic during the 1+ hours meeting. Diane, Kukhee, Ernest and Terri to meet again (Monday?) to continue.

  ACTION ITEMS

  • Terri to make schedule for Network installation and test during downtime, with input from Sonya, Kristi, Kukhee, Sheng
  • Terri to add Controller IOC installation, with input from Ernest
  •  Sonya, Till - detailed plan for BPM check-out after April start-up.
  • Sheng - develop a plan for monitoring status of this BLD version 2  'concentrator' processor
  • Kristi - which two magnet IOCs control the 4 new correctors? ltu0-mg01, ltu1-mg01
  • Diane, Kukhee, Ernest, Terri - meet to plan installation of RF IOCs
