gigabit vs. 100mb

Here's an interesting dilemma. I haven't made cables since the gigabit stuff came about, but I can't find any information on wiring changes. Here's my problem. I've strung cable for an entire office (7 modular ports) back to a punchdown block (568 A color scheme should that matter) From this punchdown block I have patch cables made from the same cabling running to a gigabit netgear 24 port switch. 5 such switches are involved in this network total, and all are linked by the same patch cables I made for the punchdown to switch cabling mentioned. All switches show 1gb speed lights for the switch to switch connections, and 6/7 punchdown to switch connections show 100mb, one shows 1gb. If I move the patch cable from the 1gb working port to any other it makes no difference and only shows 100mb. If I remove any of the 6 100mb ports patch cabling and replace the patch cable with a store bought cable, it shows 1gb and runs fine. Is there something new about attaching ends to a 100mb vs. 1gb patch cable?


thanks in advance,
Matt
