Re: SDLC, 2793 and IOP-less mode -- MIDRANGE-L

Pat.

You are right, my friend! I was using CMN03 instead of CMN04.WRKHDWRSC *CMN had the following:

Resource Type Status TextCMB01 2844 Operational Combined function IOPLIN03 2793 Operational Comm AdapterCMN03 2793 Operational Comm PortCMN04 2793 Operational V.24 PortCMB02 268C Operational Combined function IOPLIN01 6B03 Operational Comm AdapterCMN01 6B03 Operational Comm PortLIN02 6B03 Operational Comm AdapterCMN02 6B03 Operational Comm Port

That V.24 went right past me, must have been the 3 1/2 hours of sleep Igot last night.


The line is Connect Pending now.  All should be well.

Thanks a bunch.

You need to be sure you are dealing with the
correct port for SDLC.

Here is the Sales manual full description:

(#2793) - PCI 2-Line WAN w/Modem

The #2793 is a 2-line/port WAN w/modem adapter.
This feature is the non-CIM (Complex Impedance Matching)
version offered in all countries except Australia and New Zealand.

Port 0 is the modem port and supports V.92 56K Async PPP,
V.92 data modem, V.44 data compression, V.34 FAX modem and
FAX functions, such as ECM and 2D/1D conversion. Port 0 does
not provide Sync modem capabilities (SDLC and Sync PPP).

Port 1 is the RVX port and supports multiple communications
protocols, including synchronous operations.

Select one of the following cables to attach to port
0(modem port):

    * #1010 Modem Cable - Austria
    * #1011 Modem Cable - Belgium
    * #1012 Modem Cable - Africa
    * #1013 Modem Cable - Israel
    * #1014 Modem Cable - Italy
    * #1015 Modem Cable - France
    * #1016 Modem Cable - Germany
    * #1017 Modem Cable - UK
    * #1018 Modem Cable - Iceland/Sweden
    * #1020 Modem Cable - HK/NZ
    * #1021 Modem Cable - Fin/Nor
    * #1022 Modem Cable - Netherlands
    * #1023 Modem Cable - Swiss
    * #1024 Modem Cable - Denmark
    * #1025 Modem Cable - US/Canada

Select one of the following cables to attach to port
1(RVX port):

    * #0348 - V.24/EIA232 20-Ft PCI Cable
    * #0353 - V.35 20-Ft PCI Cable
    * #0356 - V.36 20-Ft PCI Cable
    * #0359 - X.21 20-Ft PCI Cable
* #0367 - Operations Console PCI Cable (ships with a 25 pin to 9pin adapter)o Multiple #0367 cables can be ordered but only one per#2793) to serve as consoles for secondary partitions when LogicalPartitioning is utalized.
ECS is supported from both the modem port, and the RVX port. Thefollowing cable is required to support ECS from the RVX port:
    * #0348 - V.24/EIA232 20-Ft PCI Cable

The #2793 does not support the remote ring indicate function.

    * Attributes provided: One RVX port and one integrated modem port
    * Attributes required: One PCI slot (3 volt)
    * For 9405 - 520 (2793)
          o Minimum required: 0
          o Maximum allowed: 69 (Initial order maximum: 0 )
          o OS level required: i5/OS V5R2, or later
          o Initial Order/MES/Both/Supported: Refer to Feature

I am getting a error when I try to vary on an SDLC line on a brand new520 at V5R3M0.. Doing some research I came across what I think is adirect hit on the problem but I don't understand the resolution. Couldone 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 V5R4M0supports only a PPP connection for ECS or Service Agent when operatingin an IOP-less configuration. This is supported only over port 0 whichis 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 positionunder a real IOP restores the functionality of port 1.
It's the "Moving the IOA to a position under a real IOP restores thefunctionality of port 1." Sounds simple enough (right?)....but howwould you go about doing this?
Thanks,
