The TSX IBX 100 module logically occupies the same slot as a TSX IBY 100 module. The position normally occupied by a TSX IBY 100 module will be empty (virtual TSX IBX 100 module slot).

The TSX IBX 100 module is connected to the X Bus by an internal floating point cable with a PCI type processor.

The slot corresponding to the TSX IBX 100 module address (physically free on the rack) must never be used by another module.

So that the TSX IBX 100 module knows of its address on the X Bus, it must be configured using the micro-switches on the module. It is also necessary to configure the switch used by the module.
