I can not configure a fax line on the 2793 card (internal modem)?
I keep getting the message; CPD27CD Line BLUE00x vary on failed.

The problem is caused by the fact that the 2793 card is operating in a IOP less configuration.
We have seen this problem on new iSeries, i5 hardware running V5R3 and V5R4. The 2793 will only
support ECS, but not asynchronous communication like fax.

IBM document 409197681:

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.


In short: Contact your local IBM hardware technician and have him connect the 2793 card with the IOP adapter.

Note: Have this IOP issue in mind, when ordering/configuring new System i hardware.
