Cisco IE-4000-4S8P4G-E Switch

[controlsguy]

I have the Cisco IE-4000-4S8P4G-E Switch and when I connect a Cisco GLC-SX-MMD transmitter into port range 1/5-1/8 I get a %PHY-4-SFP_NOT_SUPPORTED: The SFP in Fa1/6 is not supported. I can use the same transmitter in port range 1/1-1/4 and it connect fine. 

Do anyone know what I am doing wrong?

  - It's a bit strange to me that you mention Fa1/6 , because to me that seems to be an ethernet-copper port only ,

That could be the case. Ports 1/1-1/4 are Gi ports, which is why I believe my GLC-SX-MMD transmitter works without any issues. But for ports Fa1/5-1/8 everyone is saying that GLC-SX-MMD transmitter should work in those ports also, but they will not. I am just confuse with this one at the moment.

"fa" is for Fast Ethernet, which is 100Mb. GLC-SX-MMD is a gig optic and works in the 4 gig ports.
