Enterasys C5G124 SFP Modules in a stack - "unsupported pluggable module"

So this might be a similar issue to https://community.extremenetworks.com/extreme/topics/c5_b5_f_w_6_71_03_0025_issuing_unsupported_plug... but we're running the latest firmware.
We're running c5-series_06.81.01.0027 on two C5G124-48P2's.. the modules work fine when unstacked, but when stacked, we get the unsupported pluggable module error upon boot.  When we view the port status it says "Combo RJ45/Invalid/PoE".
Any thoughts?

Edit: I've tried this with both 10GB-LRM-SFPP and 10GB-LR-SFPP modules.

Hi Chris,

Those two modules (10GB-LRM-SFPP and 10GB-LR-SFPP) are not supported on the C5G124-48P2.  The C5G has 4 SFP ports, which won't support 10G modules.  For 10G modules, you need SFP+ ports.  You'd need a C5K to use your 10G modules.

I'm not sure how this could have worked in a standalone C5G.  Is it possible the standalone unit this worked in was a C5K?

Thanks, it's possible it didn't work and I just didn't notice it.  Is there a compatibility guide anywhere?  I tried searching for one before posting this question and came up empty handed.

Hi Chris,

This link will bring you to an article with a good amount of information.

https://community.extremenetworks.com/extreme/topics/pluggable_transceiver_specifications_datasheet

In addition to the information contained in the article, at the bottom, you'll see a link to a PDF.  That is the actual transceiver datasheet with specifications and compatibility for all modules that we sell.
