Controlling the System via SMBus

4.1

SMBus Overview

The PCI Express Mini Card, the microSIM cards and the PoE controller can all be
controlled using the SMBus and two I/O expanders.

Two I/O expanders and a system EEPROM are connected to the SMBus.

Figure 18.

SMBus overview

MEN offers a driver for accessing the SMBus. See

MEN’s website.
