I have two Netvanta 1544 (2nd Gen) Switches. I am attempting to connect them together using all 4 SFP ports for stacking. I have enabled the interfaces and checked all my connections but they are continuously down. I have not been able to get them to link up at all. I am on FW R13.2.3 and both switches were setup from the default config file from the Adtran site. SFP Diagnostic information pasted below. Thanks in advance!

For anyone who runs into this issue in the future. It was the JDSU transceivers that were incompatible. I replaced them with Finisar FTLF8524P2BNV transceivers and have my full 2500 Mbps on all 4 links over 1m aqua cables. I have pasted my new SFP diagnostic info below as well. Thanks!
