Preparation

This chapter contains all information that is necessary to connect an OpenStage phone to an

Asterisk based communication system.

This includes the power supply options (PoE or external supply) for each OpenStage model

and its possible sidecar combinations. To enable a secure environment, 802.1x support for

OpenStage is specified.

For autoconfiguration, LLDP-MED and DHCP can be used. In addition to the standard DHCP

options, SEN proprietary enhancements allow for assigning the address of a provisioning

service at phone startup for easy Plug & Play installation. By means of the provisioning inter-

face (WPI), mass deployment scenarios and remote administration during the phone’s lifecy-

cle are supported.

To facilitate configuration of a single phone by the administrator or user, OpenStage phones

feature a web interface in addition to the phone’s local interface.

Supplying Power for the Phones

The OpenStage phone family can be powered by

• External power supply

• Power over Ethernet (PoE)

New OpenStage

Power Supply (EU-,

US- or UK-plug) In line with the further development of our portfolio we are now able to offer

smaller and lighter power supplies for all OpenStage and optiPoint 410/ 420/

500 variants.

They feature a higher degree of efficiency leading to 14 - 19% lower power

consumption, depending on the connected devices.

Important: The new OpenStage power unit is a device of product category.

The protection concept of the power installation needs to achieve the re-

quirements of earth conductor (e.g. Schukostecker Typ F, country specific).
