Chapter 2. Hardware Setup

Port ID Numbering

Each server on the installation is assigned a unique Port ID. The Port ID is a one or two segment number that is determined by the Stage Level and KVM Port number of the KVM switch that the server is connected to.

The first segment represents the KVM Port number of the First Stage unit; the second segment represents the KVM Port number of the Second Stage unit.

A server attached to a First Stage unit has a one segment Port ID (from 1–40) that corresponds to the KVM Port number that it is connected to.

A server attached to a Second Stage unit has a two segment Port ID:

ŠThe second segment (from 1–16), represents the KVM Port number on the Second Stage unit that the server is connected to. The first segment (from 1–40) represents the KVM Port number on the First Stage unit that the Second Stage unit links back to.

ŠFor example, a Port ID of 12 - 3 refers to a server that is connected to KVM Port 3 of a Second Stage unit that links back to KVM Port 12 of the First Stage unit.

Port Selection

Port selection is accomplished by means of the GUI. Port selection details are discussed in Chapter 6, Port Access.
