2.29 I/O Link Interface Address Pinning
Introduction
Input/Output Processor (IOP) cards can be installed in any of the four types of card files that are
available for installation in a High-Performance Process Manager subsystem. The four types of card files
are:
 Left 7-Slot card file
 Right 7-Slot card file
 15-Slot card file (New design – accommodates an HPMM)
 IOP Only 15-Slot card file (exists in current PMs and APMs)
The IOP Only 15-Slot card file is a current PM/APM card file that can continue to be used when a PM or
APM subsystem is upgraded to an HPM subsystem.
I/O Link Interface configuration
All card files must be hardware configured (pinned) for an address on the I/O Link Interface. I/O Link
Interface address selection is implemented (pinned) with jumpers (or zero-ohm resistors) on each card
file backpanel.
Consecutive address assignment
The card file I/O Link Interface addresses must be configured (pinned) consecutively. However, three
addressing schemes must be considered and they are based upon the High-Performance Process
Manager’s card file configuration.
Two methods of pinning
Two methods of I/O Link Interface address pinning are described later in this subsection. The HPM files
normally use jumpers to define (pin) the card file address. Zero-ohm resistors that are used in place of
jumpers are soldered in at the factory only by special request.
