Power

Introduction

This chapter discusses the following power requirements for the 3300 ICP:

• “Installation Practices” on page 87

• “Controller Power Input” on page 87

• “MiVoice IP Phone Power” on page 88

• “Planning a Power Over Ethernet Installation” on page 95

• “Uninterruptible Power Supply (UPS)” on page 109

Installation Practices

Data signals on an Ethernet or similar connection are low power and are susceptible to

electromagnetic interference. It is important to correctly install the data equipment and

interconnections in a controlled manner to minimize electromagnetic interference onto the

cables and equipment and to minimize signal loss.

MItel strongly recommends using Uninterruptible Power Supply (UPS) units or similar power

backup systems to protect the 3300 controllers against AC power outages. For more information

on this subject, see “Uninterruptible Power Supply (UPS)” on page 109.

Follow the relevant safety and building installation codes for the location.

See Appendix B of the 3300 ICP Hardware Technical Reference Manual for details on

acceptable wiring practices, equipment installation, and equipment grounding.

Installation Power

Consider the entire voice path from one device to another when distributing power. Consider

especially which devices need to maintain power during a general power outage. Although the

end devices such as phones will continue to need power, so will the underlying network

infrastructure, if phone service is to be maintained.

The use of local UPS supplies as well as larger central power backup schemes, local generators,

for example, may need to be considered.

An example of how to calculate UPS power is given in “Uninterruptible Power Supply (UPS)”

on page 109.

Controller Power Input

The controllers have flexible power input operating over a wide range to allow global

connectivity. The units operate with standard supplies of 60/50 Hz and 110/230 VAC input, and
