Galaxy GHDX2-2130-16iSCSI Installation and Hardware Reference Manual

I2C Monitoring

3-10

3.4 I

C Monitoring

The operating status of PSU and cooling fan modules are collected through

an I

C serial bus. If either of these modules fails, the failure will be detected

and you will be notified through the various methods described above.
