Top Rung Down 140mm 154mm54mm 68mm 135mm We need 8 or 9 of these made from standard rungs

Second Rung 194mm 10mm 2mm We need 16 of these made from standard rungs

Half Rung Up 154mm54mm We will have to machine these from the current half up types if they have been made in sufficient numbers we need 8 or 9

Half Rung Down These may well have been made already we need 8 or 9

End Pieces

Card Layout 30mm 20mm 100mm 3mm 24mm 3mm 90mm 10mm 23mm 30mm 423mm HPDs Level-0 Fibre Channel Low Voltage High Voltage

Voltage solution HV power out of column with minimum of bending Other Cables can make S bend reasonably easily For columns close to top of crate HPDs

End Pieces Voltage solution HV power LV power HV mon LV mon Si Bias

Voltage solution All cables can exit form the back of the column if there is the space available For columns far from the top of crate This also allows the voltage patch panel to be in line with the cable port in the shield

Low Voltage Power

Low Voltage Sense Two 2 pin lemo cables – with approximately cat5 thickness and stiffness

High Voltage Power Have to redesign end piece to allow these very thick cables to exit column satisfactorily. Can unbolt from patch panel and feed through so not too much compliance required.

HV monitoring Goes to one 15pin sub D – may be a problem with different lengths of cables

Silicon Bias A single lemo cable – Can it come from the C board?

SPECS/ECS Single RJ45 Network Cable

Temperature Monitoring Flat cable going to 37pin Sub-D

Data Fibres 24 Fibres going to 2 break out boxes. Need to be careful of bending just after boxes. Need to be very careful of loop. Spare fibres go down front U channel by HPDs. Concerned about space for loop before patch panel. Doesn't show looping round the Lo boards to use uip fibre length

TTC Fibres 7 TTC control fibres – occupying the same space as the data fibres. Loop could be sooner to avoid too much conflict as no break out boxes to worry about.
