Hardware Description

  Rear Panel

The unit’s rear panel includes two logical Ethernet ports  and a full-range power
socket.  Although 10BASE-T and 100BASE-TX connections are automatically
sensed by the SwitcHub, you must use the Configure button to set the data
transfer mode to full-duplex or half-duplex operation, as described under 

Setting

the

 

Communication Mode 

in this chapter.  The following figure shows the rear panel.

Ethernet Ports

The SwitcHub has 2 logical RJ-45 Ethernet ports 

– 

one MDI-X port for

connecting to a workstation or server and one MDI port for connecting to
another network interconnection device, such as a hub or switch.  When using
Fast Ethernet, these ports can also be connected to devices such as a high-speed
server or Ethernet backbone.  Use straight-through twisted-pair cable to connect
to any of the switching ports.

Note: Either the Port 1 or Port 2 MDI port can be used as a daisy-chain port to connect
the switching hub to other compatible hubs using straight-through twisted-pair cable

.

  Power Socket

The power socket accepts AC power from 100 to 240V at 50 to 60Hz.  The unit
is equipped with a universal full-range power source.
