37x5 to FEP-4600 Migration and Planning Guide
707117-003 1-1
Chapter 1. FEP-4600 Overview
The FEP-4600 provides a variety of attachments using SNA and Non-SNA gateway
technology. Through use of this technology, a number of 37x5 FEP features may be
replaced, allowing many 37x5 platforms to be decommissioned.
Through its ESCON and/or FICON interfaces, the FEP-4600 and its attached resources
appears to an LPAR as one or more Control Units (CNTLUNIT macros). The number
and makeup of these Control Units is dependent upon what your requirements are.
Several types of Control Units can be defined. These are described in more detail later in
this chapter.
 PU 2 Nodes (XCA) - Provides support for traditional 3270 controllers, PC
gateways, midrange controllers (i.e. AS400), APPN nodes (NN, EN, and LEN),
standalone PCs (IBM PCOM, or OS/2), Banking ATMs
 PU 4 Nodes (SCTC) – Provides support for connections to remote 3745s and
remote channel connections including support for SNI (SNA Network Interface)
 Non-SNA 3270 (3174, 2701) – Provides support for remote 3270 controllers,
Banking ATMs
 EP-Bisync – Provides support for remote 3270 controllers and RJE workstations
Multiple Control Units of each type and Control Units for multiple LPARs (EMIF and
MIF supported) can be defined. If you attach the FEP-4600 through an ESCON or
FICON director, the FEP-4600 can provide network connections for multiple CPUs. A
properly configured FEP-4600 can use a single ESCON/FICON interface to replace
multiple Bus and Tag interfaces required by a 3745.
Each FEP-4600 platform includes two Ethernet interfaces, each capable of operating at
1000 Mbps, 100 Mbps, or 10 Mbps speeds, as part of the motherboard, and 4 PCI-X card
slots which can be populated by a combination of the following interfaces:
 ESCON (maximum of 2/platform)
 Quad Serial Interface (QSI)
 Quad Bisync Adapter (QBA)
 Quad Ethernet Interface (QET) – Maximum of 2/platform
 Token Ring
Additionally one PCI-Express slot is available for accommodating a single FICON
Interface adapter (1, 2, or 4 interfaces).
Any combination of the above cards is permitted to customize the platform for whatever
your requirements are.
