Cisco 2950 Diff between Green and Orange LED?

Hi,
I have a Cisco 2950 and most of the LED's are green, but there's one that flashes green and orange. Is that the difference in speed?

Any info would be nice!
Thanks

Amber flashing and green means crc and/or frame errors.

You might also want to check your speed and duplex settings, sometimes if the port is left on auto, it wont negotiate correctly, forcingf the port to the correct speed/duplex will stop it from flapping.

Hope this helps

To add to Colin's remark about speed/duplex mis-matches.  If you force one end of an Ethernet links speed/duplex you MUST force the other ends as well.  i.e if you have a PC connected to port 1 on a 2950 and you configure on the switch:

interface FastEthernet0/1
 speed 100
 duplex full
!

Then you MUST change the adapter settings on the PC to be 100Mb & Full-Duplex, otherwise you WILL get a mis-match and the switch will not detect any collisions.

Most modern NIC's work best left at Auto, it is generally a best practise to force fixed connections though such as switch-to-switch or switch-to-router links.
