Hi,
I am using cisco ISR 4431 router and I am trying to install sfp (GLC-LH-SM) but it is not working, as I checked on the log there is an error showing up " transreciver-init-failed "
Router IOS is IOS XE 16.6.4
Please help me to resolve this.
Thanks

It means the transceiver is dead.
What happens if the transceiver is replaced?
