I'm having a really strange problem with my Cisco 6509 and our telco patch cabling. Currently in our datacenter we installed patch pannels in our switch racks to connect those switches to servers or other switches in other racks. The cable for these patch pannel is telco style (basically it's one fat cable with a special DB connectors at each end which hooks on each side to a 48-port patch pannel). We hooked up one of our Cisco 6509s and when we try to connect it to another switch (a Cisco 2950) , we can't get any physical connectivity. Over the same cabling we can connect other Cisco switches together. The only difference that I noticed between this cable and regular cat5e is that it only uses the pairs that are needed and the pairs that are not used do not exist (our cable tester shows them as open). Does anyone have a suggestion?
