I tried both SP-A & SP-B but got the same error message…
However, I was able to get it to work …..
Used these steps:
 Connected CAT-5 between my laptop and the management Lan port on SP-A
 Network connections > Properties > TCP/IP Properties and select “use the following IP and DNS server option.
ip address: 10.75.212.A (clariion is using 10.75.212.B)
subnet mask: same as the one on the SP
default gateway – leave blank
dns server entries – leave blank
I changed the properties through SP-A/setup. And now I can ping both the SPs
I am not sure if you have suggested the same solution earlier. If you did, sorry I missed your point 🙂
SO, coming back to my original question..
Now we would like to migrate this array to another subnet..
Question is, can I use the same method again once we disconnect the SP management LAN ports from the current network switch ? AFAIk, the ip remain on the processor. correct ?
Do I need to have a complete access through pptp ?
