workstation’s hardware-monitoring chip to be active, even if the system
has been powered off.
Test Sequence and Error Messages
For detailed information about the different test sequences and error
messages, see “MaxiLife Test Sequence and Error Messages” on page 98.
MaxiLife Architecture
The MaxiLife chip continuously monitors temperature and voltage
sensors located in critical regions on the system board. This chip receives
data about the various system components via a dedicated I2C bus,
which is a reliable communications bus to control the integrated circuit
boards.
