Etherlite 160 intermittently disconnected

Realport
1

I have the above mentioned subject problem under the following network configuration.

  1. 10 units of etherlite 160 connected to first gigabite switch at IP 192.168.1.12.

  2. Anotehr 10 units of etherlite 160 connected to second gigabit switch at IP 192.168.1.13.

3.The above 2 units of gigabit switch then connect via fiber optic to gigabit switch at IP 192.168.1.11.

  1. The server with IP 192.168.1.10 and OS of Windows XP with realport installed is connected to gigabit switch at IP 192.168.1.11.

This configuration has been running fine for near 6 months. But now 2 to 3 units of etherlite 160 start to give me problem of intermittently disconnected from the network. Is anyone can help urgently.

By the way, with the above network configuration which is the proper gateway setting should be done in the etherlite 160.

Thank you. ET
