How to Console Into the Netapp S500

Hello,
I have a Netapp S500 SAN that I plan on doing some maintenance this weekend.  The maintenance I'm doing is basically changing the IP addresses of this SAN (2 IP's) to a different private address in order to move this SAN onto a separate switch/network.  Incase for whatever reason after changing the IP and I can't access it to this new IP address, I was just wondering if there is another way to connect to this to revert the changes.  Like a Cisco router or firewall, you can telnet to it, but in case you have to IP connection, you can still console into it directly.  Does the S500 have this feature?  I would assume it does.  Can someone please provide me with the instructions.  Thank you very much.

Thanks,
Wilmette

There is a serial connection on the back.  I don't remember if it's RJ45 where you'll need the converter that came with it or a 9 pin serial port but there is one on there that's for sure

Paul:
I created a different question a few weeks back about putting this S500 SAN on a separate switch.
http://www.experts-exchange.com/Storage/Storage_Technology/Q_26388865.html
Not sure if you recall, but I am at work now and attempting to do this.  I have two different IP addresses for the 2 NICs on this S500:
A = 192.168.21.23
B = 172.16.10.2
Default Gateway and DNS are left blank.  However, when I press OK to accept these changes, StoreVault Manager is telling me that the default address of 0.0.0.0 is not valid.  Anyway to get around this?

Thanks,
Wilmette

OK.

How many physical ports do you have on the back of the S500?

One of these is your production subnet and the other is the SAN subnet.  The SAN subnet should not be routable but on the interface that your production network is you should put the default gateway for it.

The S500 has 2 NIC ports, e0a and e0b.  Both of them I would like to connected to a separate SAN switch - essentially not a part of my production LAN.  Reason I'm doing this is for multipathing.  So, here is what I got after successfully getting Netapp's help, which is surprising considering that this S500 is EOL.
Srv1:
NIC1:  172.16.10.31/24, no gw and dns
NIC2:  172.16.10.32/24, no gw and dns
NIC3:  Production LAN IP, GW and DNS

S500:
e0a:  172.16.10.1/24
e0b:  172.16.10.2/24
GW:  172.16.10.31
After talking to Netapp support, they suggested to just enter the IP address of any of the server that is going to connect to this S500.  So the GW for the S500 above is the IP address of Srv1's NIC1.  After testing everything out, it looks like this worked.  I have since added a 2nd server that also had 3 NIC's, and was able to successfully connect to the S500 as well as my production LAN.  

Thanks a lot for your help Paul.

That was going to be the next recommendation, just put in a dummy default gateway since it will not be a routable network.  Good thing you still can get support on these things.
