Extension Cutdown Sheet Configuration (Figure 3-11 - Figure 3-12)

Due to the inherent flexibility of the universal PCB slot configuration, standard cutdown sheets for extension
cabling do not apply.
For example, given that a 16ESIU is installed in slot #2 and uses extension numbers 301-316, if three 16ESIU
PCBs or 8SLIU with the 8SLIDB PCBs were installed in the system in the order below, the numbering plan
would correspond as follows:
To determine extension assignments for the system cutdown, the installer must identify the following in order:
●
Order of installation
●
KSU (Controlling/Base, Expansion)
●
Slot used
●
PCB type (8ESIU, 16ESIU, 4SLIU, 8SLIU, 8SLIDB, etc.)
●
Connector used on PCB
To determine where any group of eight extensions is installed, note the order of install, KSU, slot, PCB
connector and PCB type.
Chapter 3
The order in which the extension PCBs (8/16ESIU, 4/8SLIU, 4/8SLIDB) are
installed determines the assigned extension number.
