Possible Switch LED Issue

I installed a 3750 Cisco Switch behind my Cisco 515E firewall. I plugged a straight though cable from my Fast Ethernet port on my firewall into a port. My internal network is accessing the internet with no issues at all however, I have noticed that the LED on my switch shows regular traffic flickering. Then it blinks from Yellow to green then goes back to showing regular traffic as it should. Has anyone seen this before and if so what does it mean? I am nervous about this issue.

Re: Possible Switch LED Issue

Check the duplex and speed status on the Swicth port and the Firewall port and verify both are in Full Duplex and the speed is 100 mbps

Thanks that is a great idea. I will check that to make sure it is setup that way. Thanks.
