Cisco offers the 10/100 TX Switch Module for FastHub 400 Series. The 10BaseT/100BaseTX switched uplink module has a switched 10/100 autosensing port. By default, the port autonegotiates the transmission speed and duplex mode. You can set the port to 10 or 100 Mbps and to half- or full-duplex mode. The 10/100 switch module has LEDs (STAT, DUP, and 100) that reflect the status, duplex mode, and speed of the module port.
