To replace the distribution board, see Figure 13-2on page 183 to locate parts and assemblies,
and complete the following procedure:
NOTE You can perform this procedure with the e-box mounted in the system, but some steps
are easier with the e-box removed and separated from the power supply. See
“Removing the Power Supply and the E-box” on page 154 and “Separating the E-box
and the Power Supply” on page 155.
CAUTION Always observe proper ESD procedures when servicing the inside of the e-box. Wear a
grounded wrist band, and work on a static-dissipating mat if possible. See “ESD Safeguards” on
page 139.
1. Remove the BPAP board, the demodulator board, and the two TR boards from the e-box,
following the steps in “Replacing E-box Circuit Boards” on page 151.
2. Disconnect the power cable from the distribution board.
3. Remove all the transducer connector modules and blank-off plates from the front of the
e-box. See “Replacing Transducer Connector Modules” on page 156.
CAUTION Be careful when removing and installing the transducer connector modules, to prevent damage
to the distribution board’s connectors.
