Starting rack word

When adding a Special I/O Unit online, the new Unit's allocated words must
not duplicate any words allocated to other Special I/O Units that are already
mounted. Add the new Unit to a slot position so that the allocated words will
not be duplicated. There are no other restrictions on the slot position.
CPU Bus Units cannot be added online.
With a Duplex CPU Dual I/O Expansion System, Expansion Backplanes can
be added in addition to Units. The Expansion Backplane being added must be
a CS1D-BI082D Backplane with CS1D-II102D I/O Interface Units. The start-
ing Rack word of the added Expansion Rack can be set.
When an Expansion Backplane is added, a Basic I/O Unit or Special I/O Unit
must be mounted in the Backplane. The Expansion Backplane will not be
added if it does not contain a Basic I/O Unit or Special I/O Unit.
When the Connecting Cables are duplexed, all of the Connecting Cable con-
nections must be normal. The Expansion Backplane will not be added if there
is even one Connecting Cable disconnected.
Units cannot be added to the
shaded slots because the word
addresses would be duplicated.
Units can be added in these
slots with word addresses
CIO 13 to CIO 19.
Units can be added in these
slots with word addresses
CIO 23 to CIO 29.
Units can be added in these
slots starting from CIO 33.
