Cable Replacement

Procedure

  1. Attach the new cable assembly (see Figure 2) to the coil and make sure the cable strain relief matches the notch of the former (see Figure 3). The side with Do Not Loop label of the in-cable box should face down (see Figure 3). If it does not face down, rotate the strain relief. Make sure that the cable clamp holds the cable jacket, and then tighten the cable clamp with the four screws.
    Figure 3. Cable Assembly Installation
  2. Connect all eight SMB plugs (CH1-CH8) and the DC Plug to the corresponding receptacles on the interface board. The receptacles are marked CH1-8 to correspond with the labels on the cables. Do not route RF cables and DC wires above the bosses shown in Figure 1; otherwise, the corresponding bosses on the bottom cover will squeeze the cables and DC wires when the bottom cover is closed.
