NORTEL DS1404001 NETWORK SWITCH MODULES (PASSPORT 8690SF SERIES)

The 8690SF module is optimized for high-performance switching of Layer 2 and Layer 3 traffic. The on-board CPU performs independent learning of unknown devices and topology updates so that the switch fabric is dedicated to switching critical application traffic. Two 8690SF modules can be installed for optimum performance and reliability. Both switch fabrics are used for traffic forwarding, doubling performance, and one CPU acts as the master software control engine. In the event of a SF/CPU failure, traffic is switched via the remaining SF/CPU module and control is passed to the secondary CPU automatically, in less than one second. The SF/CPU module provides a console port (DTE/DCE switch selectable) and modem port using DB-9 pin connectors; a PCMCIA slot for ATA type cards and a 10/100 Ethernet port for management. The SF/CPU module has LEDs to indicate temperature, power supply and fan tray status, CPU/SF master/secondary status, CPU and Switch Fabric utilization, and management port link and speed.
