2 High Voltage High voltage Power Supplies and HV patch panel in the Counting Room. Cables with 48 HV channels and interlock signals to the on-detector HV Distribution Boxes. Front End Modules are subdivided in 4 parts of 32 straws with separate connections to the HV Distribution Boxes. HV Distribution Box branches off three 48 channel cables into 144 SHV connectors.

4 Low Voltage One complete Front End Box draws 2.6 A from the positive (+5,3V) supply and 0.9 A from the negative (-5,3V) supply (typical). LV Distribution Box has 40 fused taps to to accommodate 36 Front End Boxes and 3 service boxes (1 ). The number of incoming cables are dependant on the selected power supplies, no power supplies in parallel. Total power for one LV Distribution Box: +5,3V -5,3V Outer Tracker Distribution Boxes 4

5 Optical Fiber Connections The Optical Receiver Card of the L1 Board accepts 12-fiber ribbon cables and connectors. A patch panel in the Counting Room and an off-detector patch panel in the cavern, in between the patch panels a bulk fiber cable with 54 ribbon cables; 39 used and 15 s. The TTC and SPECS signals also use this fiber cable. The on-detector Fiber Distribution Box combines 12 ST connectors into three 12-fiber ribbon connectors Four ribbon cables between the on-detector Fiber Distribution Box and the off detector Fiber Patch Panel; 3 used and 1. The off detector Fiber Patch Panel branches off 12 TTC ST type connectors and 12 SPECS LC type connectors. Outer Tracker Distribution Boxes 5

7 es The function is subdivided into one Master at the middle of the detector curtain and two Slave es at the top and bottom of the detector curtain. The Master contains the TTCrx and the SPECS Slave, it supplies; The TFC signals and JTAG ports for the Slave es. The I2C ports, directly connected to the Front end Boxes. The Slave contains; LVDS drivers for the TFC signals. ADC s for the monitor signals. The TFC/monitor connections from Master to Slave Service box is done by 3 CAT5 cables The TFC/monitor connections from Slave to the Front End Boxes is proposed to be made with 30 pin Metral connectors and 14 twisted pair shielded cable.
