GBIC Ports

GBIC Ports

Rookie Enterasys user here. We have a stack of 4 C5G124-48P2's. A problem yesterday caused the stack to reboot. When it came back up, regular ethernet ports 45-48 stopped working 3 slaves, but the GBIC ports 45-48 are still working. We use a mix of GBIC and the ethernet ports on that end of the switches. As a temporary work around, I moved the ethernet stuff to lower numbered ports, but I'd like to get it put back.

Any suggestions?

Hi Steve,
I believe the ports 45-48 are combo ports. You have a choice to use either the copper port or the sfp port but not both. I believe if the sfp is populated it should take precedence.

From the hardware manual the same is true for both 24 and 48 port models.
Each combo SFP port in use eliminates the availability of one RJ45 port. In other words, only 24
ports per slot can be active at any given time on components equipped with a combination of RJ45
and SFP interfaces. When an SFP transceiver in SFP port 23 establishes a link, RJ45 port 23 is
disabled. When an SFP transceiver in SFP port 24 establishes a link, RJ45 port 24 is disabled.

What firmware is running on this stack?
