INSTRUCTIONS TO REPLACE THE EMBEDDED BOARD STACK IN A CALIFIA PATIENT MODULE
BACKGROUND:
Follow these instructions to replace the existing embedded board stack in a Califia Patient Module with a new board stack.
- PREPARATION:
- Drain the reservoir in its entirety.
- Power off the unit
- Disconnect all external tubing.
- Disconnect the power cable and Ethernet cable.
- Move the Califia Patient Module to a table or benchtop with plenty of workspace.
- REQUIRED TOOLS:
- 2mm hex driver

- Place new board stack in same location. Attach the Beating Heart cable to bottom board connector, as shown in Figure 6. Mount board stack to rear panel using the same 6 screws removed in previous step, refer to Figure 5.
- Board stack is ready to attach all connectors. Refer to Figure 4. Please double- or triple-check each of the connectors to ensure they’re in the correct terminals and proper alignment. Figure 7 offers a good angle to use for comparison.

- Next is to attach power and external ethernet cable then power up the Califia Patient module. Listen for the valve initialization routine that takes place approximately 20-25 seconds after power up. Once initialization is successful, launch Califia Simulator software and connect to the Califia Patient module, as usual.
- If there are any problems or concerns, please contact Biomed Simulation personnel for support.
