Omni Switch/Router Power Requirements
Always make sure that the total power requirements of the modules in your chassis do not
exceed the limits of your power supply. To check the power consumption of your configura-
tion, refer to the tables on the following pages and add up the DC Current Draw of all modules
in your switch. The tables beginning on page 1-19 list modules without an HRE-X and the
tables beginning on page 1-20 list modules with an HRE-X.
The total power consumption of all your modules should be below the current provided by
your power supply, which is listed in OmniS/R-3 on page 1-8 for the OmniS/R-3, OmniS/R-5
on page 1-10 for the OmniS/R-5 and OmniS/R-9 and OmniS/R-9P on page 1-13 for the
OmniS/R-9 and OmniS/R-9P. For power consumption and FCC compliance information for
Omni Switch/Router VoIP modules, consult your VoIP User Manual.
♦ Caution ♦
It is possible, but not recommended, to have a
configuration in which the current draw of the installed
modules exceeds the power provided by a single
power supply. However, such a configuration would
require two power supplies and would not allow you to
have power redundancy.
