Answer:The assembly is used with compatible Agilent 1290 Infinity II/III high-speed pump modules, including G7120A.
Answer:Yes. The service item is designated as a pump mainboard with firmware.
Answer:Check module identification, firmware communication, startup diagnostics and pump pressure and flow performance.
Agilent 1290 pump mainboard with firmware is a replacement control-electronics assembly for supported high-speed liquid chromatography pump modules. The assembly is associated with the 1290 Infinity II/III high-speed pump G7120A, and its supplied firmware distinguishes it from a bare circuit board without controller software. The mainboard supports core electronic functions of the pump module but does not include the pump head, drive, pressure-sensor assembly or solvent lines. Confirm the instrument model and firmware-service procedure before ordering and installing the board. Power down the instrument and isolate all mains connections before opening the housing. Use electrostatic-discharge protection and maintain correct connector routing. Following installation, restore any required identification and configuration information, check firmware communication with the LC control software and perform module diagnostics. Functional verification should include startup, flow delivery and pressure monitoring before analytical runs resume.
