Connecting to the Network
Connecting UTP Cables to Mini-GBICs
The MGBIC‐02 has a 1000BASE‐T RJ45 copper‐wire port connection with automatic
crossover detection. This port has internal crossovers and supports automatic‐polarity
sensing.
Automatic‐polarity sensing eliminates the need for a crossover cable, regardless if the
connection is to another network device (such as a bridge, repeater, or router) or a
workstation.
To connect and verify UTP cable connections to a Mini‐GBIC RJ45 port, refer to Figure
and proceed as follows:
1.
Remove the protective covers (not shown) from the RJ45 port of the Mini‐GBIC.
2.
Ensure that the device connected to the other end of the segment is powered ON.
3.
Plug the twisted pair segment into the MGBIC‐02 RJ45 connector.
3-16 Installation
Note: The MGBIC-02 port on the 7G-6MGBIC or 7G-6MGBIC-A supports Category 5
Unshielded Twisted Pair (UTP) cabling with an impedance between 85 and 111 ohms.
Category 3 cable is not supported.
Note: Leave the protective covers in place when the connectors are not in use to prevent
contamination.
