Port ID Numbering

Each CPU Port on a CS-1754 / CS-1758 installation is assigned a
unique Port ID. You can directly access any computer on any level of
the installation by specifying the Port ID of the CPU port that the
computer is connected to - either with the Hotkey port selection method
(see p. 19), or with the OSD (see p. 28).
The Port ID is a one, two, or three digit number. It is determined by the
Stage Level and CPU Port number of the switch that a computer is
connected to.
The first digit represents the CPU Port number of the First Stage unit;
the second digit represents the CPU Port number of the Second Stage
unit; the third digit represents the CPU Port number of the Third Stage
unit.
w
A computer attached to a First Stage unit has a one digit Port ID
(from 1-4 for the CS-1754; from 1-8 for the CS-1758), that
corresponds to the CPU Port number that it is connected to.
w
A computer attached to a Second Stage unit has a two digit Port ID.
The first digit represents the CPU Port number on the First Stage unit
that the Second Stage unit links back to; the second digit represents
the CPU Port number on the Second Stage unit that the computer is
connected to.
For example, a Port ID of 2 3 would refer to a computer that is
connected to CPU Port 3 of a Second Stage unit that links back to
CPU Port 2 of the First Stage unit.
w
Likewise, a computer attached to a Third Stage unit has a three digit
Port ID.
As in the previous example, a Port ID of 2 4 1 would refer to a
computer that is connected to CPU Port 1 of a Third Stage unit, that
links back to CPU Port 4 of a Second Stage unit, which, in turn, links
back to CPU Port 2 of the First Stage unit.
