Network Connection
Before the FrameScope 350 is attached to a network, it is constantly checking for a connection. When the FrameScope 350 detects that it has been plugged into a network device it does the following:
•Measures the length of the cable (optional). This feature can be disabled through the Network Settings wizard. After the connection is made, the length of the cable is displayed on the network map on the Main Menu.
•Listens for a link pulse or traffic to determine which cable pairs are being used for transmit and receive. If this operation fails, a dialog pops up informing the user of the error, and the FrameScope 350 continues to listen for a link. This condition usually means that the network device is not turned on, or the connection from the FrameScope 350 to the device is faulty.
•
•Uses DHCP to obtain the following (optional):
•IP address
•IP subnet mask
•Default gateway
•DNS server
•NetBIOS node type
•NetBIOS Name Server (WINS)
The user can manually set these parameters through the Network Settings wizard. These parameters are displayed on the Network Settings Window. If DHCP fails, a dialog pops up informing the user and asking if DHCP should be retried or if the FrameScope 350 should give up. DHCP may fail if the DHCP server is not accessible from the FrameScope 350’s connection point or if the DHCP server’s security is configured to deny access by unknown devices.
