Important Notice About B2Gxxx-xx 10/100/100 and SFP Mini-GBIC Ports
SFP Mini-GBIC uplink ports are used in an either / or configuration with their corresponding RJ45 10/100/
1000 Mbps 1000BASE-T Gigabit Ethernet copper ports. If all Mini-GBIC ports are used, the four
corresponding RJ45 ports will be disabled. The maximum number of active ports can be 24 on the
B2G124-24, and 48 on the B2G124-48 and B2G124-48P, in any combination of RJ45s and Mini-GBICs. This
does not apply to the B2Hxxx-xx switches.
Note: You can use a wildcard (*) to indicate all of an item. For example, fe.3.* would represent all
100Mbps Ethernet (fe) ports in slot 3, and ge.3 * would represent all 1-Gigabit Ethernet (ge) ports
in slot 3.
