Cross Brand - Hang errors, Micro Channel mainframe connection.
Applicable to: World-Wide
Symptom:
Intermittent channel hangs or host timeouts may be experienced on PS/2 systems which have the MicroChannel to mainframe connection adapter (formerly the system/370 channel adapter) FRU Part Number 12G8067.
The MMC adapter card allows micro channel based systems to be attached to a system 370 or a system 390 mainframe system block multiplex channel it is capable of providing S/370 control unit functions under microcode control.
Combined with other I/O adapter cards and associated software, the MMC allows a micro channel based system to act as a S/370 control unit capable of transferring data between itself and a processor channel at up to 4.5 MB per second.
The MMC card requires appropriate application software to be loaded both on the host and on the PS/2. Refer to the "Personal System/2 System/370 Channel Adapter Installation and Testing Instructions" (Document No. GC23-0594-01). The processor channel control I/O program must be configured with "shared=N".
