5508 as a backup for 4402

[robot2000]

Hi

My customer has a 4402-25-K9 and need a backup (failover) controller to avoid data transmision break when primary controller goes down.

4402 are end of sale  so I have a question can I use 5508 to get Controller Failover Protection with 4402 ?

regards

Marcin

Hi Marcin,

Yes, this is a supported configuration. Have a look at this recent thread

Hi Marcin,

You are most welcome my friend I think the great NetPros in this thread

offer some excellent tips and strategies for this plan as well as the restrictions

you will encounter moving forward. You will likely want to make the 5508 the

primary controller with an eye on moving away from the 4400 at some point

due to it's EoL and inability to run the latest code versions.

Cheers!

Rob
