Installation 26

Site Preparation

This section describes how to prepare your site for a successful Synapse system

installation.

Network Requirements

For more information on the network configuration, see “Planning Your System

and Network Configuration” on page 15.

 A switched network topology is recommended for your LAN (using standard

10/100 Ethernet switches that carry traffic at a nominal rate of 100 Mbit/s).

 The office LAN infrastructure should use Cat.-5 (or better) cable.

 The LAN connections to Synapse devices should all be wired. However, wireless

connections to other devices (such as laptops) in your office network that are not

part of the Synapse system will not impede performance.

 All devices in the Synapse system must reside on a single subnet.

 A DHCP server is recommended and must be on the same subnet as the Synapse

system so that IP addresses can be auto-assigned. If no DHCP server is present,

you can assign static IPs if desired. DHCP or static IPs are only required if the

system is to be managed from a routable network and/or automatic time

updates from an NTP server are desired. Synapse devices will self-assign

link-local IP addresses for all voice communication in addition to any DHCP or

static IPs that are assigned for management purposes.

 Unless you want to manually set the Synapse clock and manually upgrade

Synapse software, an Internet connection to the LAN is required.

 A DNS server is recommended to resolve the path to the Internet and to the AT&T

server for software upgrades.

 If a routing path to the Internet is not available, the system administrator can

download the upgrade files and use the WebUI to upgrade the software

manually.

 For users whose computers require a GigE Ethernet frame rate (a gigabit per

second), use separate Ethernet connections for the Deskset and the computer.

The Ethernet connection through a Deskset is limited to 100 Mbits/s.

Placement Considerations

Avoid placing any Synapse component too close to the following:

 Communication devices, such as television sets, DVD players, or other cordless

telephones

 Excessive heat sources

 Noise sources, such as a window with traffic outside, motors, microwave ovens,

refrigerators, or fluorescent lighting

 Excessive dust sources, such as a workshop or garage

 Excessive moisture
