∙Firmware update supported for the Fast EtherHub-12mi models via out-of-band Xmodem file transfer through the serial port, or in-band TFTP file transfer over the network
∙One slot supports optional slide-in network extender modules for connection to 10BASE-T, 100BASE-TX, 100BASE-T4 or 100BASE-FX (on a separate segment)
∙Transparent bridging (between stack and external device) via optional network extender modules
∙Uses adaptive cut-through switching (which dynamically changes between fragment free cut-through and store-and- forward depending on the CRC error rate)
∙100BASE-TX SmartExtender module automatically senses transmission speed (at 100 Mbps or 10 Mbps)
∙100BASE-TX and 100BASE-FX SmartExtender modules support two interface modes: full duplex or half duplex — auto-negotiates transmission mode for full duplex and half duplex (if same feature is supported by attached device); otherwise can be manually configured
∙Automatically learns MAC addresses to build the routing information database
∙Automatically filters local traffic
∙Transparent to all higher level protocols
∙Flexible installation for desktop or rack (standard 19” size)
