CUSTOMERS ONLY 12 TYPICAL SYSTEM APPLICATIONS Simple 8-Port Switch The ELAN 8x10 chip can act as a stand-alone managed or unmanaged switching device in low-cost, compact switch applications. Such a switch can be created from ELAN 8x10 chips (one for every 8 ports), a bank of two 256k x 16-bit 60 nsec EDO chips per ELAN 8x10 chip, a 32k x 8-bit EPROM or EEPROM for initialization and configuration information, two LXT944 or similar quad Ethernet Interface Adapters, and suitable passive components (filters, transformers, crystal oscillators, etc.) A block diagram of a typical 8-port 10BaseT stackable switch is given below. The PCI expansion bus allows multiple ELAN 8x10 switch assemblies to be easily stacked up to a maximum of 64 10Mbit/s ports. Managed 8-Port Ethernet Switch The above system will operate as a fully managed system simply by replacing the 32k x 8-bit EEPROM with a 256k x 8-bit EPROM or EEPROM containing the SNMP agent, support firmware, spanning tree, and TCP/IP stack. Low-cost 10/100 Mbit/s Switch The ELAN 8x10 chip can be part of a 10/100 switch using the ELAN 1x100 10/100 Mbit/s switch chip. Together they can form a workgroup or desktop switch supporting a high-speed server or backbone port in low-cost, compact Ethernet switching hub applications. Such a switch can be created from one or two PM3351 devices (one for EDO DRAM 10BaseT Ports 1-4 10BaseT Ports 5-8 Quad 10BaseT Interface ELAN 8x10 PM3350 Quad 10BaseT Interface EEPROM PCI Bus Expansion Bus |
