A replaceable coin cell CR2032 3V battery is mounted on the planar to provide backup power for the
Real-Time Clock and CMOS RAM on the ICH9 chip.
G. Field Replaceable Units (FRU)
The planar contains a serial EEPROM to contain FRU information including Dell part number, part revision
level, and serial number. The Advanced Management Enablement Adapter (AMEA) also contains a FRU
EEPROM. The backplane’s SEP and the power supplies’ microcontroller are also used to store FRU data.
