2950 connectivity to network

[evsrcs]

We are replacing Baystack 10/100 hubs in all remote remote locations. We have purchased 24 2950 switches and I have a question on their configuration.
We are placing them in remote locations which have 1751 routers. Not having much experience configurig Cisco equipment I just did basic config (ip address, mask, and gateway info.The manual says to use a crossover cable to plug into the router. When I use a crossover cable and boot the switch all lights come on except the one with the crossover cable in it and the switch doesn't work. If I use a straight cable the light comes on but the switch doesn't work.
If I plug the Baystack back in the 1751 router and plug the 2950 into the Baystack hub with a crossover cable - everything works. We just need a basic config. Should I not have a default gateway configured.
I've included the config. from the 2950 - any help would be greatly appreciated. If I put more than one 2950 at any location do I connect them together with crossover cables??

My config is attached.

Don't use a crossover, use a straight cable for connection to the 1721. If you connect 2 switches together with a 10/100 port then you will need to use a crossover, by default the port will come up as a VLAN trunk as well but you might want to disable this and force the ports as access-ports. You should probably force all the ports to access-mode to disable DTP:

interface fastethernet 0/1
switchport mode access

Also to speed up the port start-up times enable spanning-tree portfast, this can be done under global configuration with the command:

spanning-tree portfast default
