VSP725 Administrator and Provisioning Manual
Network Requirements
A simple VSP725 SIP deskset installation example is shown in Figure 1. 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 VSP725 requires a wired connection to the LAN. However, wireless connections from
your LAN 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 VSP725 desksets so that IP addresses can be auto-assigned. In
most cases, your network router will have a DHCP server. By default, the VSP725 has
DHCP enabled for automatic IP address assignment.
If no DHCP server is present, you can assign a static IP to the VSP725. You can assign a
static IP address using the VSP725 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 VSP725 firmware and/or
configuration settings manually.
For users whose computers require a GigE Ethernet frame rate (a gigabit per second), use
separate Ethernet connections for the VSP725 and the computer. The Ethernet connection
through a VSP725 is limited to 100 Mbits/s.
Figure 1. VSP725 Installation Example
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.
