The number of error frames for the input port (PortA) for node address 4 is 31, so you can see
that error frames were received on the input port for node address 4.
Therefore, you can assume that there is a problem between the output port (PortB) for node ad-
dress 3 and the input port for node address 4.
This corresponds to location (A) (B) or (C) in the network configuration diagram.
Concretely, you can assume the following possible error locations.
• The device at node address 3
• The cable between the output port at node address 3 and the input port at node address 4 or
the connectors at those ports
• The device at node address 4
