ASA5515X-IPS management 0/0 to LAN

Question

I've recently setup two ASA5515X in A/S each with IDS. When I had them in the lab I was able to access the IPS's via IME but now that it's at the datacenter it's not working (of course). I've got the IPS configured with an IP on our LAN and the ASA's Management0/0 interface configured as:
interface Management0/0
no nameif
security-level 100
no ip address
management-only
The Management0/0 interface is plugged into a switchport on our LAN VLAN. From the ASA it's seeing the IPS as Up and I've verified the IPS network settings. Any ideas? Did I forget something? TIA!

When I run "show interfaces" I only get statistical information, nothing L2:

   Total Bytes Received = 0
   Missed Packet Percentage = 0
