Network Requirements - VTech VCS754 Administrator And Provisioning Manual

Network Requirements

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/Cat.-5e cable.
The VCS754 requires a wired connection to the LAN. However, wireless connections to
other devices (such as laptops) in your office will not impede performance.
A Dynamic Host Configuration Protocol (DHCP) server is recommended and must be on
the same subnet as the VCS754 conference phones so that IP addresses can be
auto-assigned. In most cases, your network router will have a DHCP server. By default, the
VCS754 has DHCP enabled for automatic IP address assignment.
If no DHCP server is present, you can assign a static IP to the VCS754. You can assign a
static IP address using the VCS754 menu. Go to Admin settings > Network setting > Set
static IP. If you do not have a DHCP server or do not manually assign static IPs, you will
not be able to access the WebUI and/or enable automatic time updates from an NTP
server.
A DNS server is recommended to resolve the path to the Internet and to a server for
firmware and configuration updates. If necessary, the system administrator can also
download upgrade files and use the WebUI to update the VCS754 firmware and/or
configuration settings manually.
Introducing the VCS754
Some DHCP servers have default settings that limit the number of network IP
addresses assigned to devices on the network. You should log in to your server
to confirm that the IP range is sufficient.
