4.6.2 RJ45 Twisted-Pair Data Ports
The M2100 series switches may have several 10/100BaseTX ports that allow connection to
standard CAT-5 UTP cable with RJ45 male connectors. The RJ45 receptacles are directly
connected to the chassis ground and can accept shielded CAT-5 cables. If shielded cables are
used, care must be taken to ensure the shielded cables do not form a ground loop via the shield
wire and the RJ45 receptacles at either end.
