About the PowerTap
The PowerTap can provide overcurrent protection to the thick cable, 7.5A for
each trunk. (Country and/or local codes may prohibit the use of the full
capacity of the tap.) You can also use the PowerTap tap with fuses to connect
multiple power supplies to the trunk line without back-feeding between
supplies. PowerTap taps are used only with round media.
In cases in which the power supply provides current limiting and inherent
protection, you may not need fuses/overcurrent devices at the tap.
About the DevicePort tap
DevicePort taps are multiport taps that connect to a round or flat media trunk
line via drop lines. DevicePorts connect as many as 8 devices to the network
through mini or micro quick disconnects.
Micro DevicePorts
All device connections are micro female receptacles; only micro male
connectors with rotating coupling nuts can interface with each port. A number
of trunk connection style options are available.
