SDLC, 2793 and IOP-less mode

I am getting a error when I try to vary on an SDLC line on a brand new 520 at V5R3M0.. Doing some research I came across what I think is a direct hit on the problem but I don't understand the resolution. Could one of you hardware gurus chime in? 

The description of the proposed resolution is from an IBM support document:
The 2793 2-port WAN adapter card (IOA) at Releases V5R3M5 and V5R4M0 supports only a PPP connection for ECS or Service Agent when operating in an IOP-less configuration. This is supported only over port 0 which is the internal modem port of the card. In IOP-less mode, port 1 (external RS-232 port) is non-functional. Moving the IOA to a position under a real IOP restores the functionality of port 1.
It's the "Moving the IOA to a position under a real IOP restores the functionality of port 1." Sounds simple enough (right?)....but how would you go about doing this? 

Thanks,

Pete Helgren
