Polycom Viewstation FX/EX Series

  1. Go to System Info > Admin Setup > LAN/H.323 > LAN/Internet > LAN & Internet (admin password required)
  2. Configure these settings:
Setting Description
Host Name Indicates the system's DNS name.
The LAN Host Name:
  • must begin with a letter and end with a letter or number
  • may include up to 63 letters, numbers, and hyphens
  • is not case sensitive

Note: If you change the Host Name, the system restarts.
WINS Resolution Sends a request to the WINS server for WINS name resolution.
DHCP Specifies how the system obtains an IP address.
  • Client Ñ The system gets an IP address from the DHCP server on the LAN. The DHCP server also supplies the DNS server address, default gateway, subnet mask, and WINS server address. If the DHCP server is not available, the system cannot get an IP address.
    • Off Ñ The IP address will not be assigned automatically. You must enter the IP address, DNS server address, default gateway, subnet mask, and WINS server address manually. Server Ñ The ViewStation FX or VS4000 systemÕs internal DHCP server assigns up to 12 IP addresses to network devices. Assigned IP addresses range from 1.1.1.2 to 1.1.1.14. To use this option, you must enable it during a SoftUpdate.
Note: Do not use this setting if the ViewStation FX or VS4000 is connected to a LAN with a DHCP server. The setting will not take effect if the system is on a LAN with an active DHCP server.
If the system has previously been configured as a DHCP server, it reverts to being a DHCP client when it is connected to a LAN and restarted.
IP Address Displays the IP address currently assigned to the system.
If the system does not automatically obtain an IP Address, enter the IP address here.
DNS Servers Displays the DNS servers currently assigned to the system.
If the system does not automatically obtain a DNS server address, enter up to four DNS servers here.
