PCB STARTUP
Initial PCB Installation
To avoid unexpected extension/trunk numbering if the VoIP PCB registers with the system
first, install the VoIP PCB after the other types of extension/trunk PCBs have been installed.
The order in which SLIU-S and ESIU-S PCBs are physically inserted determines the numbering plan.
The installer must install extension PCBs in order (i.e.; slot 3 first, slot 4 next, etc.) for a sequential number-
ing plan.
For example, as the CPU provides 8 digital station ports (ext. 301-308), when 2 more station cards are
installed in the following order, the numbering plan below would apply:
Refer to PCB Port Assignments on page 2-35 for details on the port usage with the VOIPU-S PCB and
VOIPDB-S. As these cards are assigned trunk ports when initially installed, this could impact the number of
ports available for extensions.
