2.5 Network Connection
2.5.1 Connection to Devices
Each of the switch’s twisted-pair ports can be used to connect to a con-
troller or other devices. Use a straight-through twisted-pair cable with RJ-
45 connectors on both ends. The twisted-pair cable extended from a
twisted-pair port is called a “twisted-pair segment”. It can be up to 100
meters long. You can connect any RJ-45 (MDI-X) station port on the
switch to any device that uses a standard network interface such as a
workstation or server.
2.5.2 Connection to other Hubs or Switches
ADAM-6520 has five RJ-45 ports that support connections to 10 or 100
Mbps Ethernet networks, and half or full-duplex operation. ADAM-6520
can be connected to other hubs or switches via a two-pair straight through
cable or crossover cable. The connection can be made from any port on
ADAM-6520 (MDI-X) to other hubs or switches by either their MDI-X
port or uplink MDI port.
ADAM-6520 supports auto-crossover, so each port allows you to connect
switches together and expand an existing network easily using either
straight through or a crossover Ethernet cable. You can connect any RJ-
45(MDI-X) port on the switch to a device like a switch, bridge or router.
