Installation
NOTE
This unit cannot detect a change to its IP address if the change is due to a change in networks from a wiring closet or through software, such as a change to a router configuration. Reboot the system if the DNS changes.
Specifying a Locally Configured IP Address
Dynamic Host Configuration Protocol (DHCP) is used to dynamically allocate and assign IP addresses. DHCP allows you to move network devices from one subnet to another without administrative attention. You can choose to enable DHCP if a DHCP server is present. If you disable DHCP, you must enter an IP address (the locally configured IP address if not assigned by a DHCP server), subnet mask (used to partition the IP address into a network and host identifier), and gateway (IP address of the default gateway the system uses).
Specifying the Hostname and Domain Name Service (DNS) Servers
You can enter the hostname of the system and the IP addresses to configure DNS servers. You can also enter the domain names to search when resolving hostnames. Domain Name System (DNS) translates names of network nodes into addresses; specify this preference to use DNS to resolve the hostnames of devices to IP addresses.
Specifying Network Speed
If you choose an option other than Auto for the Administrator Preferences : Network : General : Network Speed preference, ensure that it matches the speed and duplex configured on your network switch.
NOTE
If your Ethernet switch is configured for half duplex, you may experience poor quality video when placing calls greater than 512 Kb/s.
To work around this issue, change your Ethernet switch configuration to a setting other than half duplex when using Auto for the Network Speed preference.
