This documentation is intended to assist with the installation of the core components of an IP Office system running in Avaya IP Office Essential Edition mode. It describes those components and factors that should be considered for an installation. Installation in other modes is covered by separate manuals.

The term IP500 V2/V2A is used to refer to both the IP500 V2 and IP500 V2A control units.


The IP Office is a converged voice and data communications system. It should therefore only be installed by persons with telephony and IP data network experience.

Installers must be trained on IP Office systems. Through its Avaya University (AU), Avaya provides a range of training courses including specific IP Office implementation and installation training. It also provides certification schemes for installers to achieve various levels of IP Office accreditation.

It is the installer’s responsibility to ensure that all installation work is done in accordance with local and national regulations and requirements. It is also their responsibility to accurately establish the customer’s requirements before installation and to ensure that the installation meets those requirements.

You should read and understand this documentation before installation. You should also obtain and read the Avaya Technical Bulletins relevant to recent software and hardware releases to ensure that you are familiar with any changes to the IP Office equipment and software.

This document does not cover the addition of an IP500 V2/V2A system as an IP500 V2 Expansion System system in a Server Edition or IP Office Select network. However, the hardware compatibility notes for the control units in this manual remain applicable unless stated otherwise.

The Avaya IP Office IP500 V2 is also known as "IPO IP500 V2 Cntrl Unit", "IP Office IP 500 v2", "IPO IP500 v2", "IP 500 V2", "IP500 V2",  "IPO 500v2 System Unit Assembly" or "IP Office 500 v2".
