1. Introduction
SG9224B is a non-blocking high performance Ethernet switch engine, integrated with 24
ports of 10/100Mbps and two ports of 10/100/1000Mbps. Each port can be either
auto-sensing or manually selected via EEPROM initial configuration or CPU on-line setting
to run at 10Mbps or 100Mbps or 1000Mbps speed rate, full or half duplex mode, enable or
disable flow control capability, the detail advance feature see the manual.
