+
+According to a [blog post](https://rsaxvc.net/blog/2020/8/15/Nokia_G-010S-A_Pin_6_Issue.html), some manufacturers designed their SFP ONTs in a way that doesn't 100% comply with the SFF specification. A solder mod like described in a [dslreports thread](https://www.dslreports.com/forum/r32529545-) might be required to get certain SFP modules to work with this card. This mod grounds `MOD_ABS PIN (6)`, which signals to the card that a module is inserted in the slot. This signals the card to send power to the SFP module.
