5.6 Connecting to the 10/100BASE-T
Network Management Ports
These ports are labelled NET MGMT and are 10/100 Mbytes/sec Ethernet ports for
carrying network management traffic only. If you are concerned about the security of
your management network, we recommend strongly that you place the Network
Management port on a different subnet from the Data Network ports.
The port has integral green Link Present/Active and Link Speed indicators.

packets are being transferred. When LED A is flashing it indicates that a link is
established and packets are being transferred.
Note – 4T_D3P and 4T_D4P pins provide a common-mode termination for unused
lines.
