Power Switch

The power switch toggles power on and off to the unit. The switch can also be used to reset the hub.

AC Power Connector

The EtheRx hubs use an auto-sensing 100VAC-240VAC, 50/60Hz internal power supply. Connect the AC power cord from the rear of the unit to an AC electrical outlet.

AUI Port

The AUI port is a 15-pin D-sub connector. It is a general purpose port for backbone or mixed media connections for 10BASE2, 10BASE5, 10BASE-T, or FOIRL connections using a proper external transceiver.

BNC Port

This port is labeled BNC, and has a built-in transceiver for direct 10BASE2 connection using thin coaxial cable. Use RG-58 A/U or RG-58 C/U type cable. Refer to Appendix B for 10BASE2 cabling guidelines when connecting to this port.

Stacking Ports

The two ports are labeled“Stack-In”and “Stack-Out”for stacking up to five

(5)EtheRx Pro-Series hubs in any combination of 16-Port and 24-Port models. Refer to the section, “Stacking EtheRx Hubs” on the next page for instructions.
