EBME Forums Forums Maintenance Spare Parts requirement of Infinity serial hub

Thank you guys for the answers.
But 3COM Hub does not suit me as it is just used just as a repeater hub.
The infinity serial hub is used as a main switching hub with Recorder CPS connected to it(recorder port). I could not find any hub or switch locally that has the recorder port.The 3COM hubs do not have the recorder port.
So for my purpose only the Infinity serial hub is the answer. Any help is appreciated.
