1. A cabling support facility for installation of interprocessor unit of a multi processor unit system in a first network system in a first network, comprising:
- a second system for directing the cabling interconnections of a first system, having plurality of processor unit in each of said processor unit of the first system having,a device access controller connected through a second network to a second system,each device access controller including a memory for storing a unique identifier,a network controller to interconnect to a network controller of at least one other processor unit, and,in association with the network controller,a selectably settable anchor bit indicator to indicate a processor unit selected as a first processor unit of the first network,a next connection indicator connected from the device access controller, andconnected from the network controller,a transmit test indicator connected from the device access controller, anda receive indicator connected from the device access controller,whereinthe second system is responsive to a user command indicating a configuration for the first network for(a) interrogating each of the processor units of said first system through the second network by reading the anchor bit indicated and the unique identifier of each of said processor unit to wherein the anchor bit indicator and the unique identifier indicated that the processor unit is of the first network,(b) determining a connection sequence of the interconnecting cabling of the first network,(c) writing the next connection indicator of the first processor unit to indicate a first cabling connection,(d) upon receiving an acknowledgment of a first cabling connection to the network controller of the first processor unit entered by the user, writing the next connection indicator of the next processor unit in a cabling configuration,(e) upon receiving an acknowledgment of a next cabling connection to the network controller of the next processor unit in the cabling configuration, writing the transmitted test indicator of the first processor unit and reading the received test indicator of the next processor unit to confirm the first cabling connection,(f) selecting a next first processor unit and repeating steps (c) through (e) for successive pairs of processor units in the order of the processor units in the cabling connection configuration, each next processor unit of a pair of processor units becoming the first processor unit of the next pair of processor units, until(g) all cabling connections of the configuration have been completed.

Abstract
A support facility for installation of interprocessor unit cabling interconnecting the processor units of a multiple processor unit system in a first network, including a second system for directing the cabling interconnections of the first system and, in each processor unit of the first system, a device access controller connected through a second network to a second system, each device access controller including a memory for storing a unique identifier, and a network controller to interconnect to a network controller of at least one other processor unit. There is a selectably settable anchor bit indicator to indicate a processor unit selected as a first processor unit of the first network, a next connection indicator connected from the device access controller, and connected from the network controller, a transmit test indicator connected from the device access controller and a receive indicator connected from the device access controller. The second system identifies the units of the first system and directs a user through the cable interconnections of the first network.
