YIKES! Cisco UCS Manager Not Discovering Connected Servers

Help!

I am trying to connect a UCS c240 M5 server to a pair (one active, one passive) of Cisco 6454 Fabric Interconnects. The server is connected to the FIs with a 25gig uplink. The Cisco flavor of ESXi is installed on the UCS server.

It is apparent in the ESXi GUI that the UCS c240 M5 can "see" the Fabric Interconnect. ESXi reports that it knows it is connected to a device running NX-OS (the OS on the Fabric Interconnects) and that it knows it is plugged into Eth1/37 on the device, which is true.

Now here's the rub...

UCS Manager is not "discovering" the new UCS c240 M5 server that I have connected to it. UCS Manager, does however, see the 10 previous servers that have been connected (these servers are all HX 220c M5 boxes).

What am I doing wrong? What do I need to do in order for the new UCS c240 M5 to show up in UCS Manager?

Thank you for all of your help!!
