8-5-1 Back End Processor Replacement Procedure
NOTE: There are specific differences in the BEP Processor replacement procedure between replacing a BEP1
or BEP 0 (Pentium III-based BEP, earlier type) with a BEP2 (Pentium 4-based BEP, newer type). The
variations between the two types are clearly shown in the procedure steps.

Use the appropriate flat and Phillips-type screw drivers and a wire cutter, as indicated in the back end
processor replacement procedure.
8-5-1-2 Preparation
Shut down the Vivid 3N Pro/Expert ultrasound unit, as described in Chapter 3 - Installation.
NOTE: If the BEP is to be replaced, remember to perform a full incremental back-up of the
Archive and User Presets - refer to the 8-7-1 "Software Installation/Upgrade Procedure"
on page 8-115.
8-5-1-3 Back End Processor Removal Procedure
1) Remove the Vivid 3N left and right side covers, as described in 8-2-2-3 "Side Covers Removal

NOTE: The following step is performed if removing a BEP2 (Pentium 4-based BEP, newer type).
3) Remove the BEP2, as follows:
a.) Remove the two screws of upper BEP bracket, see Figure 8-54 "BEP - Position of Brackets on
BEP2 Models" on page 8-58.

c.) Disconnect all the cables from rear of the BEP, leaving the HASP key (option plug) connected.
NOTE: When replacing the BEP, the HASP key must be moved to the new BEP. You will need to
connect the HASP key to the parallel port. Make sure you perform a full incremental
back-up of the Archive and User Presets before replacing the BEP - refer to the 8-7-1
"Software Installation/Upgrade Procedure" on page 8-115.
