Thanks for the response! So, I have it connected to a switch and tried to SSH into it via PuTTY at the IP address it had (found via Wireshark) and was given a login prompt, but without the login details, I'm stuck right there. We do have another NetApp device in there (Model FAS2240-2, version 8.2.5P5 7-Mode), which I believe is a controller (I was able to connect to it both via SSH and using the NetApp OnCommand software), but this is my first time trying to set one up from scratch, so I'm flying blind.
In the end, what my management wants is to have a networked share drive where they can just dump data for archival. I've worked with a 2720 in the past but by the time I got it, it had already been configured, so I was just working with it from a maintenance perspective.
