1. SFP ports 23 and 24 will only establish a link when the RJ45 port equivalent is not linked. (For example, when
SFP port 23 is linked, RJ45 port 23 is deactivated. When the SFP is not linked, the RJ45 port 23 is reactivated
and can establish a link as long as the SFP port 23 is not linked first.)
