Hi,
We have some IE-2000-4S-TS switches which we need to use with 100Mb copper connections. These switches were purchased specifically for our mixed 100Mb and 1Gb requirements in an industrial facility.
We cannot get GLC-TE SFPs to work / identify when plugged into the 10/100 SFP ports.
GLC-TE sfp's have been plugged to the fastEthernet SFP ports.
FastEthernet 1/1 is down, line protocol is down (err-disabled)
...
...
Full-duplex, 100Mb/s, link type is auto, media type is unknown

Thanks @MHM Cisco World.
This is the from the log:
*Jan 2 00:00:34.166: %PHY-4-SFP_NOT_SUPPORTED: The SFP in Fa1/1 is not supported
*Jan 2 00:00:34.166: %PM-4-ERR_DISABLE: gbic-invalid error detected on Fa1/1, putting Fa1/1 in err-disable state
So, as suspected, I've purchased the wrong modules

First i would like to clarify FastEthernet means (100MB) and Gigabit Ethernet means (1000MB)
GLC-TE is Gigabit SFP Module for Ethernet Copper connection, (this work 10/100/1000 speed subject to parent device where you plugging in)
So this does not mean you can plug this module in 10/100 port to work as expected. You need to plug this SFP Module in to Gigabit port so it works as expected in the above mentioned statement)
Read some guide lines and use the right port for this to work :

Thanks BB. I will have a spin through that guide.
I think I have just learnt an expensive lesson...
Do you know if the following SFP will definitely work in a FastEthernet (100Mbit) SFP port?
IE-2000-4S-TS-G-B | GLC-FE-T-I | 100 Mbps | SFP | 100m | Cat5e/6A | Copper | RJ-45 | Copper | -40 to 85C | IOS 15.2(3)E1 | — |

I have not tried it or tested, so if you have spare you can test and report back.
