5.3 Recommended Network Configuration
This section describes 2 recommended network configurations for maintaining LAN synchronization.
When connecting the unit to a network described in recommendations 1 and 2, it is not necessary to perform
LAN synchronization diagnosis. In network environments other than those described in recommendations 1
and 2, performing a LAN synchronization diagnosis is necessary. If the network fails this diagnosis, reconnect
the CS to the switch which OK CS is connected to and perform a LAN synchronization diagnosis again. If the
network fails this diagnosis, LAN synchronization cannot be used. In this case, using air synchronization is
recommended. For details about air synchronization, refer to "5.6 Air Synchronization".
Recommendation 1: Physically separate the LAN synchronization
communication channels
•
Do not connect other terminals/computers to the switches that the CSs are connected to or the switches
on LAN synchronization communication channels between CSs.
Example: SW2 and SW3 in the figure below.
•
Use Panasonic-recommended switches for the switches that the CSs are connected to and the switches
on the LAN synchronization communication channel between CSs.
•
When connecting 32 or more CSs, use gigabit switches for the switches that the CSs are connected to
and the switches on the LAN synchronization communication channel between CSs.
•
Configure the installation so that CS synchronization communication is not mixed with the communication
of other terminals between switches. As long as communication is not mixed, it is possible to connect CSs,
other terminals and switches that connect to other terminals, to the same switch.
