Engineering Guidelines

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 113.
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 113.
