Network information
When planning your installation there are certain critical considerations for the network connections. The fol-
lowing sections describe such considerations for several types of network interfaces.
Network diagram
Draw a network overview diagram that displays all neighboring IP nodes, connected elements and
telephony components.
IP related information
Before you can set up the basic IP connectivity for your SmartNode 4400 series you should have the following
information (see table 6):
• IP addresses used for Ethernet LAN and WAN ports
• Subnet mask used for Ethernet LAN and WAN ports
• IP addresses of central H.323 Gatekeeper (if used)
• IP addresses of central PSTN Gateway for H.323 based calls
• IP addresses of central TFTP Server used for configuration upload and download
Configuration tools
You will need a PC (or equivalent) with a VT-100 emulation program (e.g. HyperTerminal) to configure the
software on your SmartNode 4400.
AC Power Mains
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. Install a power conditioner if necessary.
Refer to “Connecting power” on page 30.
Note When setting up your SmartNode you must consider cable-length
limitations and potential electromagnetic interference (EMI) as
defined by the applicable local and international regulations. Ensure
that your site is properly prepared before beginning installation.
