Unable to get link lights on Chelsio T520-SO using SFP+

I'm new to working with fiber so please bear with me.

I've got a Dell R520 that I've just installed a Chelsio T520-SO fiber adapter into. The server is running Ubuntu 18. I've got a compatible Chelsio SM10G-SR:10G transceiver on the adapter side and the switch (HP5406) which is using a HP short-range 10G transceiver. Between the transceivers, I have a 3-meter aqua fiber cable. I have another server with the exact same transceivers, T520-SO Chelsio card, and the same exact cable that the previous administrator installed, which is running great. I've even tried swapping everything between the existing server and the new server, but have been unable to establish an active link or get link lights while in Ubuntu.

Ubuntu sees the card and interfaces just fine. When I was in the Dell UEFI BIOS and viewed the network adapters, the switch link light lit up. Not sure if this meant the link was good or not.

I've installed the Chelsio Unified Wire drivers, configured link speeds to 10G, disabled auto-negotiation, and disabled FEC per documentation found here, I.3 and I.4 sections: https://service.chelsio.com/store2/T5/Unified%20Wire/Linux/ChelsioUwire-3.13.0.1/Chelsio-UnifiedWire-Linux-UserGuide.pdf

Here's some additional information:

Any clue where to go next? No network activity and it seems to assign it's IP just fine.
