DAQ firmware update discussion

DAQ installation

Jeff Tice will organize moving DAQ to IR2 (will use scissor jacks)
- 14 COBS and a single RTM (borrowed from Owen)
Target date is Friday
- Real RTMs are 1.5-2 weeks away
Need 10G fibers between DAQ and Diagnostic Cluster
We need power cables
- Stuart will order cables and get delivery estimate after meeting
Power: 9x308v under the floor.
- 4 are attached to the rack PDUs
- 2 are attached to cooling door
DAQ has two active power supplies, and 2 "hot" spares
- Might need outage to redistribute power

FPGA can store 4 versions of firmware
- One boots by default (Slot 0)
- Possible to boot any of the 4
We are currently not using the most recent version of firnware (5-7 version behind)
- Science rafts are at Step 0.
- Corner raft(s) already at Step 2.
Available (or soon to be available) firmware releases:
- Step 1:
  - Possible to update SCI to support PGP firmware load, without changing REB firmware
  - No changes to firmware except to add PGP firmware load
- Step 2:
  - Changes reset behavior, get rid of automatic reset after loosing link (version 335)
  - (Global and SCI resets are independent)
- Step 3:
  - Multiple mains, and synchronous step, primitive (nonusable LAM)
  - This will require CCS update to support
- Step 4:
  - Look at me (not implemented on DAQ side), multiple sequencers
  - CCS will need update to support multiple sequencers (on branch).
  - Should be backwards compatible if only use one sequencer
- Step 5:
  - id register fix (not yet available)
  - DAQ fixes: Configuring transeivers (more reliable link)
  - OTM Redundancy (temporary bad things may happen if you power both halves of OTM)
Notes:
- DAQ 2.5 will work with all existing firmware
- This would be sufficient for 9 raft running and would allow multiple image clients
- DAQ 2.5.x will require Step 4 or 5
