Adding ME424 to existing ME4024

Hello

I am getting a ME424 to add disk array to the ME4024

What are the steps to add the array or configure the management port for the ME424

Per instructions, It say to

1. power down the ME4024

2. cable SAS the ME424 to ME4024

3. power on ME424

4. Power on ME4024

then what is next? will the ME4024 see the ME424 or is there additional steps to set up the ME424

What about the management port for the ME424

Thanks

Then what is next
