i have Catalyst 2950 24 port switch and i am trying to run it in my store. i have breif knowledge of configuring cisco swtiches but google was/ is my friend and i was able to reset and factory default the switch to the original state.
Now i have 21 Ethernet plugs across the store , but when i connect all 21 ethernet cable none of them work. no blinking or green light what so ever on the switch , i have tried everything and when i connect any pc directly to the switch , it works but not from the main cables hub .
it's so frustrating and i don't know what to do.
i don't wanna hire anyone to fix it for me because i wanna learn as well.
i know the switch works fine , but there is something wrong between the cables inside the dry wall and the switch . it does not seem there is any connectivity. note i tried to plug some of these cables to Linksys wrt54g router and there is connection when i go plug number 1 in the showroom, but not when i plug that cable in the switch
Solved! Go to Solution.
yes i can .
now if you can give me a basic setup configuration for the switch i dont need anything beside all 24 ports to work. i have a clothing company and i don't need a complicated network here
thanks for your answer
Please check the link below:
It has all you need to start working with your new switch
no there is not crossover
because the cable themselves work if i connect them to linksys wrt54g wireless router.
so either 2950 is faulty which im sure it's not or simply i am doing a good job configuring the switch correctly
Note that the Linksys router does have a "switch" inside, so it has the same wiring as the 2950 switch and has a different wiring than a regular PC or Server or Router. Therefore, could you try using a cable between the 2950 and the other devices which has a different wiring? E.g. if you're using straight now, try using a crossover.
For more details and explanations about the differences, please refer to the following link:
well you were correct i discovered that the switch works only with crossover cables and the installed cables i have are straight cables .
and since the mini linksys (workgroup ) switch i was testing supports crossover conversion (mdix) , i was able to get signal from 2950 .
i don't think catalyst 2950 support Auto mdix which is bad , so i guess i have to purchase short crossover cables or make them myself.
but hey at least i learned something new and you guys helped me alot thanks alot
Thanks for the confirmation and for giving us an update. The 2950 and Linksys router do not support auto-mdix unfortunately.
