When connecting a pc directly to the fiber convertor, we have full connectivity without any dropped packets when we do a continuous ping to the other office. But, when we connect the fiber media convertor to the switch we have connectivity issues as we get only one or two replays out of every 8 to 10 pings. I have also used a cross over cable from the media convertor to the switch, but that did not help. We are using the same equipment as we did before the move and I have attached images from other setup which should help you understand our setup. The fiver convert is a Cables to go Multimedia convertor 10/100.
Here is a more detailed description:
We have two offices in two separate buildings. ( Main Building and small building). We had and existing setup that was working fine. After we moved around the server room in the small office we are having issue connecting to the main building. We had fiber going in between bulding and than fiber media convertor at each end and finally the from the convertors to the switches at each end . In the main office we have two Cisco switches and at the small building we have a 16 port Dell switch.
All was working fine until we moved around the server room which required us to extend fiber cable that was coming from the fiber box (tray) to the Ethernet convertor. After we did this , I have full connectivity when I connect a pc directly to the media convertor, but I have connectivity issues when I connect the media convertor to the switch. This is the same switch that was being uses. When pinging something on the other side out of several pings, I only get one or two replays, but the rest fail. I also tried using another 4 port switch for testing, but I had the same results. fiberbox.jpg photo-3.JPG
When you connect to the PC do you use auto speed and auto duplex detect, or do you hard code speed and duplex?
When connecting to the switch do you use auto/auto or fixed speed/duplex?
I would try configuring the switch port to fixed 100 Mbps full duplex and try using a cross over cable.
