Circuit Board Replacement Precautions - GE Datex-Ohmeda Aisys Carestation Reference Manual

Aisys

9.1 Circuit board replacement precautions

9-4
The Aisys anesthesia system has processors on several boards. On three of these
boards, information such as the machine serial number and optional ventilation
modes (PCV, SIMV, and PSVPro) are stored redundantly.
During power-up, the machine serial number and installed options information stored
on the boards are compared. If one board differs, information from the two agreeing
boards will be written to the new board. If three boards differ (in the case of two boards
replaced) the system defaults to "NO OPTIONS" and default machine serial number.
To retain the installed options, install only one replacement board at a time.
If multiple boards are to be installed, install the first board, load software on the new
board, and power-up the machine in normal mode. Repeat this procedure for each
board installation.
The following table lists the actions required after replacing printed circuit boards:
Board Name (Short Name)
Display Unit CPU (DU CPU)
Anesthesia Control Board (ACB)
Power Controller (PCB)
Ventilator Interface Board (VIB)
Electronic Mixer (Mixer)
Agent Delivery Board (ADB)
All Others
