Software tools
You will need a PC (or equivalent) with Windows Telnet or a program such as Tera Term Pro Web to config-
ure the software on your SN4120.
Power source
If you suspect that your AC power is not reliable, for example if room lights flicker often or there is machinery
with large motors nearby, have a qualified professional test the power. Patton recommends that you include an
uninterruptible power supply (UPS) in the installation to ensure that VoIP service is not impaired if the
power fails.
Location and mounting requirements
The SN4120 is intended to be placed on a desktop or similar sturdy, flat surface that offers easy access to the
cables. Allow sufficient space at the rear of the chassis for cable connections. Additionally, you should consider
the need to access the unit for future upgrades and maintenance.
