POINT POINT POINT
(1) Precautions for selecting [Do not maintain a network connection]
When selecting [Do not maintain a network connection], the GOT is disconnected from the network at the
addition of a device with the same IP address as the GOT.
Therefore, there is a possibility that the running GOT cannot be communicated by IP address setting mistakes
or intended actions by malicious users, and the system control may be influenced by those errors.
Please change the setting of [Behavior of duplicate IPs] after carefully examining the necessity.
(2) Precautions for using a switching hub compatible with the spanning tree protocol
For the switching hub port connected with the GOT, configure the setting (PortFast or others) that makes the
GOT be ready for communications (forwarding state). The setting is required to make sure that the delay right
after the connection by the spanning tree protocol does not occur.
Without the setting, the Ethernet IP address duplication is not correctly detected.
Additionally, the GOT may not be connected to Ethernet correctly.
For the setting that makes the GOT be ready for communications (forwarding state), refer to the user's
manual for the switching hub used.
