yes.  note that ports 21-24 are combo ports.  This means you can either use the rj45 ports or the sfp ports 21-24 at one time.
I have a CX4-120 , PC8024F and several hosts.  I am using 10g iSCSI to connect several of the host.  I do not have a 1g iSCSI mod for the cx4 and wanted to know if I can connect to the 4 ethernet ports to get iSCSI traffic to 1 of the hosts. So , fiber from CX to SFP on the 8024F and I want to connect ethernet to the 4 ethernet ports on the 8024 to a host.  Will traffic run this route? I know the 4 etho ports will slow to 1g.
