37x5 to FEP-4600 Migration and Planning Guide
707117-003 2-17
Example
In the example diagram:
1. A PU 2.0 platform connects to the FEP-4600 through an interface configured to
accept dynamic connections.
2. An XID exchange results in the submission of an XID of ‘01700123’ by the PU
2.0 platform.
3. The XID is linked internally by the FEP-4600 to a host connection that matches
the XID ‘01700123’. This match is assigned to Subchannel Address 00 by the
FEP-4600 configuration. Other vital information is part of this configured CU
definition such as:
 ESCON interface number
 LPAR number
 CUADD
 Link through an ESCON switch (optionally)
4. The FEP-4600 establishes communication to VTAM over Subchannel 00.
5. SNA PU 2.0 communication flows end to end.
