Port ID Numbering

Each CPU Port on an installation is assigned a unique Port ID. You can directly access
any computer on any level of the installation by specifying the Port ID using the Hot Key
port selection method, or from the OSD Main Menu.
The Port ID is a one, two or three digit number. It is determined by the path taken from
the first stage through any additional stages in order to reach that CPU. 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; the third digit represents the CPU Port number of
the Third Stage.
1. A CPU connected to a First Stage unit:
The Port ID is a single digit corresponding to the port where the CPU is connected.
2. A CPU connected to a Second Stage unit:
The Port ID has two digits. The first digit corresponds to the port where the Second
Stage unit is connected. The second digit is the Port ID on the Second Stage unit
where the CPU is connected. For example, a Port ID of 23 refers to a CPU that is
connected to Port 3 of a Second Stage unit that, in turn, is cascaded down from Port 2
of the First Stage unit.
3. A CPU connected to a Third Stage unit:
A computer attached to a Third Stage unit has a three digit port ID. The first digit
corresponds to the port on the First Stage, the second digit to the port on the Second
Stage and the third digit to the port on the Third Stage. For example, a Port ID of 241
refers to a CPU that is connected to Port 1 of a Third Stage unit, that is cascaded
down from Port 4 of a Second Stage unit, which, in turn, is cascaded down from Port
2 of the First Stage unit.
