Cisco 2955 port LED turns amber after assigning to VLAN

I am having issues configuring a Cisco Catalyst 2955. First off, we have many of these switches on our LAN and I am using the same config on this 2955 as the others. WIth the factory default config, port LEDs are green when plugged in. As soon as I assign a port to a VLAN, the port LED turns amber and does not forward. My first thought was the IOS so I upgraded the IOS to match our other switches but no change. I also tried resetting to factory default config, confirm green LED on port, assign port to VLAN (no other config changes whatsoever), and BAM, amber LED. Seems strange this would be a hardware issue but are there any other ideas?

Does that VLAN exist in vlan database on that switch?

Turns out the switch had VLAN data from some other LAN. I was under the impression that the switch had not been used previously. Your question led me to the answer. Thanks.
