Hi Mr Scott Fella, I just told them do that.
They installed module GLC-TE in port 1, and GLC-LH-SMD= in port 2 and restart the device.
But after reboot, two ports SFP still in 1G and Still link down ( The picture i send )
Please give me some advice.

Hi Mr RRudling,
Yes, We knew GLC-LH-SMD is 1G SFP. But I dont know why when my customer installed GLC-LH-SMD=, the controller still power up led 10G. but no led in the port 1 and port 2. In WebUI, status of two ports is " link down "

Hi Mr Leo Laohoo,
They plug GLC-TE in port 1, GLC-LH-SMD in port 2 and restart the controller.
After boot up, the led 10Gb bright, but status in two ports is " link down "
Port 2: GLC-LH-SMD have line in from switch
Port 1: GLC-TE No line in, just plug in the module
