P20 cannot obtain IP address across fiber

P20 cannot obtain IP address across fiber

I am just starting getting some zero clients up but stuck pretty early in the game. Have a P20 that will not obtain an IP address, the problem being it doesn't see the network.

I'm using a fiber connection with a AT-SPFX/2 adapter in the SFP slot. It isn't the normal one that comes with the fiber P20 clients, it is another adapter I had to order.
(for reference: www.alliedtelesis.com/p-2383.html)

I was originally told that this adapter would work but I fear I may need to install some firmware to make it works since it doesn't even see the network at this point. Its amazing how much you miss link lights when they aren't there anymore.

Anyone else have this problem previously?
Thanks in advance!
