Connectivity
Four Media Connectors
This repeater has four types of ports and media connectors:
❑ AC input power connector
❑ 10Base5 (AUI) network backbone port
❑ 10Base2 (BNC) network backbone port
❑ Four/Eight STP/UTP 10Base-T (RJ45) ports
These four types of connecting media are described in the following
sections.
AC Power Connector
While it is common to use dedicated power circuits or power
conditioners to supply power to network devices, the source must be
able to provide AC power at 100-120 VAC, 0.5A, and/or 200-240VAC,
0.25A, and 60/50 Hz (for North American models). This aids in isolating
the network equipment from electrical power “noise.”
The AC power connector is located on the back panel and provides
connectivity for an internal power supply. It accepts 100-120 or
200-240 VAC from the rear IEC power entry port. The three-pin power
receptacle, shown in Figure 8, requires a three-pin male connector.
