Power Connector
The Series 6600 Switches do not have a power switch; they are powered on 
when connected to an active AC power source. These switches automatically 
adjust to any voltage between 100--127 and 200--240 volts and either 50 or 60 
Hz. There are no voltage range settings required.
Switch Features
The features of the Series 6600 Switches include:
■ 24 auto-sensing 10/100/1000Base-T RJ-45 ports with Auto-MDIX or 24 
SFP+ 10-GbE ports. The 6600-24G-4XG has only 4 SFP+ 10-GbE ports.
■ Four dual-personality ports—either the auto sensing 10/100/1000Base-T 
RJ-45 or the mini-GBIC can be used for each port. The 6600-24XG does 
not have these dual-personality ports.
■ An auxiliary (USB) port for processing a USB command file.
■ Plug-and-play networking—all ports are enabled—just connect the 
network cables to active network devices and your switched network is 
operational.
