## Introduction

The Telos Infinity INF-MXP-20 is a key Expansion Panel designed to work as part of the Telos Infinity ‘matrix-free’ IP networked Intercom system. Each INF-MXP-20 provides an additional 20 contact keys in a 1 RU space to a Telos Infinity INF-MP-16 Master Panel that it is paired with.

The INF-MXP-20 connects to the INF-MP-16 Master Panel via a 1000Mbps Ethernet network. It is powered by PoE (Power over Ethernet) either directly from the network switch or via an external PoE source. Additionally, a screw-lock 12VDC inlet is included on the rear Panel, which may be used as primary power if PoE is not available, or as part of a redundant power design (recommended and encouraged).

This chapter covers the installation, configuration, and pairing with the associated Master Panel. Refer to the [INF-MP-16 Digital Intercom Master Panel section](/v1/docs/v24-inf-mp-16-and-ds-16-digital-intercom-master-panels) for more information before proceeding.
