Hi Haviong a few issues with a cisco 2106 controller dropping connections, but cisco have said it looks like a firmware issue but will not provide us with the new firmware update without a smartnet subscription, any one else had similar dropping out with this controller?? Thanks

got them free in with the kit so might as well use them! have not tried the secondary firmware yet? someone mentioned today the j4858c only supports 62/125 fiber, maybe this is were its going wrong!

well its up again today, but have not restarted them yet fingers crossed, going to try a firmware update to the lastest software and hopefully that will improve things!

thanks ill try it and see, ill also try upgrading the firmware and setting to full duplex, cheers

yes checked both ends, plugged into the console port and checked the logs on each nothing is shown, checked for dust etc on the fibre, if the switch is powered down it seems to take hours before the fibre functions again, the only thing I have not tried yet is upgrading the firmware! its all brand new kit aswell!

thanks ill give that a go, no it was a 10 metre prejoined cable that we purchased maybe the fibre is faulty?

I have tried copper and it seems to work fine, i have left the switch on auto for port settings, and dont have another switch or modules to try?

Hi, we bought them as a package from a supplier with the modules checked with hp and they are definatelly the correct ones, the fibre cable is also brand new and i have checked for any dust etc and all seems fine, the only thing I have not done is upgrade the firmware on the switches, it seems to work after a while but then goes off I have checked the logs on the switches and nothing is mentioned, the modules do have hp wrote on them and were security sealed thanks very much

Hi I have just installed 2 hp 2610 switches with SX-LC (J4858C) modules in each linked with lc to lc fibre at 10metre length, for some reason the link keeps dropping between the two and the module lights go off, after sometime they come back again, it is a basic install with just a ip and subnet on each switch and all the default settings left intact! any ideas as to what could be causing it to keep establishing and dropping the connection? Thanks!
