This section explains how to connect external 1000 Base T copper ports to the Metro-
Switch using the standard Category 5, 5e or 6 cables. The maximum cable length is
typically 100 meters or 328 feet.
Insert the Category 5 or 5e cable into the RJ-45 connector on the Rear I/O module until
the self-locking tab clicks into position. Connect the opposite end in to a device
containing a 10/100 or 10/100/1000 Base T port. Two types of cables are used when
connecting the Metro-Switch controller to the network. A workstation or "straight
through" cable is typically used to connect Ethernet adapters to switches. A “crossover”
cable may also be used to connect controllers back-to-back. This configuration is useful
for diagnostic purposes or when a hub or switch is not available.
Note(1): The Metro-Switch supports “auto-MDIX” mode where a crossover cable is not
required when directly attaching two ports back-to-back.
Note(2): Cables used for Gigabit networks must use all 8 wires. In 10 and 100 modes,
wires are dedicated for transmit or receive while in Gigabit mode, data is transmitted
and received over all 4-pairs (see pinout diagram below).
