Links using SFPs from RAD in rear ports of X440-G2 don't become active

Links using SFPs from RAD in rear ports of X440-G2 don't become active

New Contributor
Trying a SFP from RAD in a Extreme X440-G2-24t-GE4. using the SFPs in the back of the chassis. When connected the state on the switch is Enable Ready. When I put the SFPs in a 440-G2-24P the ports come active and I am able to communicate with them.

The difference is that the 24P I am using the front SFP and the 24T I am using the rear SFPs.

The SFP that I am using are RAD MiRICi-E1T1. It is essentially an Ethernet-to-E1/T1 bridge in an SFP form factor.

The SFP-side is a gigabit Ethernet interface that plugs into any MSA-compliant SFP slot and provides Ethernet connectivity to the switch.
The ‘outside’ port on the SFP is an RJ45 E1/T1 connection.

Are there any licensing requirements on port 25-28 of a 24t-GE4 switch that would be preventing the link from coming up?

When you have rear SFP Ports, this is a 10GE4 Model with SFP+ Ports on the rear.
That means, you need to configure these ports to speed 1000 if you are using 1G modules. modules with less than 1G wouldn't work

There's no licensing preventing that.
To be clear, the X440G2-24t-GE is model 16541, and the 24p is a X440G2-24p-10G (model 16533), correct?
