Initial Extension PCB Installation

1. Plug the PCBs into each KSU slot in numerical order. The order in which the station PCBs (SLIU,
ESIU, 082U) are physically inserted determines the numbering plan. The installer must install
extension PCBs in order (i.e.; slot 2 first, slot 3 next, slot 4 next, etc.) for a sequential numbering plan.
For example, with a 16ESIU in slot #2 (ext. 301-316), when 3 more 16ESIU PCBs are installed in the
following order, the numbering plan below would apply:
Adding a daughter board to increase the available ports or going to a higher capacity PCB (ex: 8ESIU to
a 16ESIU) may require that you delete the slot and reinstall the PCB. In the following example, to add a
daughter board to slot 3, the PCB must be removed, deleted in Program 90-05-01, then reinstalled with
the daughter board attached otherwise the additional ports would not be recognized. This however, will
use new ports for the combined PCB - the initial ports (ports 17-24 using the example below) are not
used.

2. The system will automatically recognize each PCB as it is installed in the system. If a PCB has previously
been installed in a slot and another type of PCB is to be installed in that same slot, the PCB must be first
be removed from the KSU and then the slot definition removed using Program 90-05 prior to installing the
new PCB.
This same condition applies to extensions and other devices connected to the system. For example, if a
port was previously used for a keyset and a DSS Console is to be installed in that same port, it must first
be undefined in Program 10-03 before the console is connected.
