Cable Replacement Procedure

Procedure

  1. Remove the coil from the magnet room. Wear the ESD wrist strap to avoid electrostatic discharge.

    Systems with the RRx receive chain use the A-port system cable and four P-port connections.

  2. Position the coil so that the bottom side faces upward.
    Figure 1. Coil Bottom
  3. Remove all screws.
  4. Remove the cable from the coil.
    1. Remove the cable ties.
      Figure 2. Cable Connections RRx System
    2. Disconnect all RF cables and DC cables.
    3. Remove the cable clamp from the coil.
    4. Remove the cable assembly.
  5. Install the new cable:
    1. Attach the new cable assembly by sliding the strain relief of the cable into the cutout of the housing, with its round section toward the bottom. Press the strain relief down firmly, so that the edge of the housing fits into the groove of stain relief.
    2. Reinstall the cable clamp.
    3. (For A-port system cable) Install all channel connections (8 coaxial and 4 DC connectors) by matching the designators on the cable with the designators on the PCB.
      • Tie cables J5, J6, J7, J8, and P5 to the left cable tie holder on the PCB.

      • Tie cables J13, J14, J15, J16, and P6 to the right cable tie holder.

      • Route the cables as shown in Figure 2, so none of them touch the rectangular shield.

      • Cables P3 and P4 should not be tied.
