• Low Voltage cables
• - all cables tested and ok (modulo 50cm)
• BF patch panel- tighten screws (55Nm), 18/18
• - reroute sense wires, 18/18
• - mount patch cords, 8/18
• put protective covers, 8/18
• To be done
• check last 50cm of sense wires (inside I/O
  racks, from power supply to Burndy connector)
• test procedure defined, can fix ourselves

6
HV

• 36 cables/Redel from I/O racks to BF, tested and
  OK
• 4 HV patch boxes installed (2 new on I07, 2
  exisiting on O07)
• 36 new cabels/Redel pulled from CR4 to I/O
  racks, new ISEGs- 44 connectors put and tested
  by company w/ 3kV- all Redel connectors
  delievered/ mounting work in progress

7
Ethernet

• All connections tested
• All labels now OK
• Re-crimpig of some 10 cables done by company
• Re-check some 10 connections

8
LV h/w interlocks

• 4 racks connected, commisioning w/ DCS team
  4-Dec-2007
• 1 more rack (O26) needed for pre-trigger /
  cosmics run
• 5 remaining racks, cabling by workshop at PI,
  put in Jan-2008

9
TTC Fibres

• All fibres pulled, identical lengths
• Box to protected additional fibre length will be
  put by company
• Check connections to be done

Other Cables

• Optical readout fibres 18/18 OK, 1 plug in
  patch panel and 1 connector were replaced
• Power distribution box cabeles all checked, 4
  re-crimped, re-check of 4 to be done
• Pressure sensors 18 cables pulled, to be
  commisioned
• Grounding 2 (A-side) 2 (C-side) cables per
  SM, pins were welded last week, was re-done
  Dec-03-2007, to be checked
