2.8 IOP Card Files
Introduction
Additional Input/Output Processor (IOP) card file slots can be added to any High-Performance Process
Manager by the addition of one or more 7-Slot (Left or Right) or 15-Slot card files. CE Compliant 7-Slot
or 15-Slot card files that accommodate only IOPs are designated IOP card files. The IOP card files are
electrically the same card files as the card files that HPMM cards occupy. They have the same backpanel
but differ mechanically. Each IOP card file accommodates either 7 or 15 IOPs. A 15-Slot IOP card file is
illustrated in Figure 6 15-Slot IOP Card File
.
In cabinets that are upgraded from a PM or APM configuration to an HPM configuration, IOP Only card
files may exist. These 15-Slot IOP Only card files are restricted to IOP and optional I/O Link Extender
cards.
Total number of card files
The number of card files that can exist in a single High-Performance Process Manager subsystem is
dependent upon the mix of 7-Slot and 15-Slot card files. This includes card files that are designated
HPMM or IOP card files. Eight I/O Link Interface addresses are available for use in the HPM subsystem.
Each card file must be assigned an I/O Link Interface address. Two 7-Slot card files can share the same
I/O Link Interface address if one is a Left card file (slots 1-7) and the other a Right card file (slots 9-15).
The 15-Slot card file (HPMM or IOP type) cannot share its I/O Link Interface address with another card
file. It is conceivable that sixteen 7-Slot card files can exist in a HPM subsystem (eight Left 7-Slot and
eight Right 7-Slot card files).
Remote card file installation
IOP card files can be installed at remote locations by the use of I/O Link Extenders as well as locally in
the HPM cabinet or cabinet complex.
Total number of IOPs
Depending upon the configuration of IOP types, up to 40 primary IOPs, 40 secondary (redundant) IOPs,
and 3 I/O Link Extenders (a maximum of 8 I/O Link Extender cards) can exist in a single HPM
subsystem.
