Network Ports
■ On the 6600-24G and 6600-24G-4XG Switches there are 24 auto-sensing 
10/100/1000Base-T ports. All these ports have the “Auto MDIX” feature, 
which means you can use either straight-through or crossover twisted-
pair cables to connect any network devices to the switch.
■ On the 6600-24G and 6600-24G-4XG Switches there are four dual-person-
ality ports. Use either the 10/100/1000Base-T RJ-45 connector, or install a 
supported ProCurve mini-GBIC for fiber-optic connections. 
Dual-Personality Port Operation. By default, the RJ-45 connectors are 
enabled. If a mini-GBIC is installed in a slot, it is enabled and the associ-
ated RJ-45 connector is disabled and cannot be used. If the mini-GBIC is 
removed, the associated RJ-45 port is automatically re-enabled. 
■ On the 6600-24XG Switch there are 24 SFP+ 10-GbE ports. SFP+ ports 
only support 10 Gbps operation; 1 Gbps mini-GBICs are not supported in 
any SFP+ port.
