2.4 Connections

2.4.1 Connection to the Devices

ADAM-6521 modules have one fiber and four RJ-45 ports. Each of the
switch's twisted-pair ports can be used to connect a station 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," and 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.

2.4.2 Connection to Other Hubs or Switches

ADAM-6521 modules have four RJ-45 ports that support connection to
10Mbps Ethernet or 100Mbps Fast Ethernet, and half or full-duplex oper-
ation. ADAM-6521 modules 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-6521 modules (MDI-X) to other
hubs or switches either by either an MDI-X port or uplink MDI port.
ADAM-6521 modules support auto crossover to make networking easier
and more flexible. You can connect any RJ-45 (MDI-X) station port on
the switch to any device such as a switch or a bridge or router .

2.4.3 Connection to a Fiber Network

Connect to a fiber network segment with a two strand fiber. All you need
to remember is to connect the Tx (transmit) port of device I to the Rx
(receive) port of device II, and the Rx (receive) port of device I to the Tx
(transmit) port of device II.
With fiber optic transmissions you can reach speeds up to 100 Mbps, you
can block all noise interference from the system, and the transmission dis-
tance goes up to 2km for multi-mode fiber, or 15km for single-mode
fiber.

Please use the dust cover that was shipped
with your ADAM-6521 modules on the fiber-optic
port if it is not being used.
