Important Notice About C2G1x4-xx 10/100/100 and SFP Mini-GBIC Ports
SFP Mini-GBIC uplink ports are used in an either / or configuration with the C2 front panel RJ45 10/100/1000
Mbps 1000BASE-T Fast Ethernet copper ports. If all Mini-GBIC ports are used, four of the RJ45 ports will be
disabled. The maximum number of active ports can be 24 on the C2G124-24, and 48 on the C2G124-48 and
C2G124-48P, in any combination of RJ45s and Mini-GBICs.
