Rack Layout

Why revisit this now?

• Tentative layouts around for some time
• Now pressure from Chris Parkman to enter information into his database:
  • Which crates are in which racks
  • Estimated power consumption:
    Receivers, PP, CP, JEP, ROD, TTC

Changes since original layout

• Cables will be laid without connectors. So we will only need two holes in the shielding wall, not three
• Number (and layout?) of holes has changed - but we dont have the details yet
• CTP and TTC are off centre on the floor below

New proposal

• New suggested rack layout:
  • Shift trigger racks to one side
  • Easier access to most crates
  • CP and JEP above CTP
  • Use two shielding wall holes (centre and side)
• Still need to decide cabling and layout between receivers and preprocessors
• Still subject to global optimisation of level 1 trigger latency
