...
- install all new fiber and new switches, leave old private switches in place for RF, BPMs, BLENs
- configure new switches for all BPMs, BLENs, RF eiocsRFEIOs (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, KuhkeeKukhee)
- 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?
- Terri will determine the overall schedule for this work, with input from Kristi, Sonya, Sheng, and Kukhee
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 will have been tested as described above. After start-up we must schedule time for the following installation plan:
- test new code in one IOC that control the new fast correctors.
- If it works, boot into both IOCs and leave it running about 1 week
- once they check out, boot the code into a IOC that does not control a new corrector, leave it running for about a week
- Finally, reboot all magnet IOCs with new code.
BPMs and BLENs
involves 18 BPM IOCs, and 2 BLEN IOCs. Sonya pointed out that the undulator BPM IOCs do not have EIOCs so their network setups will be more like the Magnet IOCs ( NIC1 for Channel Access, NIC2 for FCOM).
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 - Terri and Ernest can plan to install the Controller IOCs with the network installations.
BLD IOC
A version 2 of the BLD IOC needs to be installed once we have the 1) Bunch Charge Feedback, the 2) Longitudinal Feedback, and the 3) LTU Launch Feedback running and providing their States data over FCOM. This will not likely happen until later in the summer. We discussed that this IOCs NICs will be dedicated to 1) FCOM and 2)Photon Multicast network - leaving no NIC for Channel Access. Sheng to think about whether having Channel Access is necessary, and alternative ways to monitor this VME if there is no channel access.
