Can you give some more information:

- Have you configured these for static IP addresses or DHCP?

- When you say “accessible” how are you defining this? Have you tried pinging all 3 devices when only 1 is “accessible”?

- You can get it into a state where “everything is fine”. What do you need to do to get back to the bad state?

Hello,

I have three NF CA5351 Current Amplifiers and use Ethernet/LAN to access them remotely.

(product webpage: https://www.nfcorp.co.jp/english/pro/mi/loc/pre/ca5351/index.html )

For some reason which I don't know, they would behave erroneously.

Only one of them is accessible remotely, and after several seconds, the accessible one will change.

That is,

only no. 1 is accessible,

several seconds passed,

only no. 2 is accessible,

several seconds passed,

only no. 3 is accessible,

several seconds passed,
