Card Enclosure Layout - IBM AS/400e User Handbook Manual

PCI Card Placement Rules
– X.25: On the Two-Line WAN IOA (#4745) or the Two-Line WAN IOA with Modem
(#9771) if more than 64 Virtual Circuits are required per IOA.
– Frame Relay: The Two-Line WAN IOA (#4745) or the Two-Line WAN IOA with Modem
(#9771) are to be used for Frame Relay.
– SDLC: If more than 64 controllers are to be attached per line on the Two-Line WAN
IOA (#4745) or the Two-Line WAN IOA with Modem (#9771).
– IPX: If IPX protocol is to be used on the Two-Line WAN IOA (#4745), the Two-Line
WAN IOA with Modem (#9771), or any LAN IOA.
– LAN: For best performance recommendations for the high speed LAN IOAs (#4838,
#2744, or #2743).
– ATM: For best performance recommendations or if there is a need to run multiple
emulated LANs on an ATM IOA (#4815, 4816, or #4818).
• The Integrated Netfinity Server has a unique set of rules that are separate and
distinct from the rules for the other IOPs and IOAs. These rules are described in
"Integrated Netfinity Server IOP Rules" on page 293. These rules are automatically
enforced by the configurator.
Note
If the configuration rules and restrictions are not fully understood and followed, it is
possible to create a hardware configuration that will not work, marginally works, or quits
working when a system is upgraded to future software releases.
The intent of this chapter is to provide guidance in configuring IOAs and IOPs so that the
system is sized to meet customer expectations. The "Configuration Validation Procedure" on
page 283 describes a simple method of determining whether the IOAs selected and their
usage will overburden a specific IOP.
It should also be noted that this section does not cover the migration towers that can be
attached to the Model 8xx server. For configuration rules related to migrated hardware, see
the description of the affected features to be migrated the AS/400e System Builder ,
SG24-2155.

Card Enclosure Layout

This section describes the layout of the card enclosures for the various system and
expansion towers. For information on the Migration Towers (#5033, #5034, #5035, and
#5077), see the AS/400e System Builder , SG24-2155.
