NETWORK CONFIGURATION
| The EX7000 Network Configuration page can be seen in Figure | |||
| attempt to locate a DHCP server. If one is found, the IP address assigned by the DHCP server will | |||
| be assumed, along with subnet masks, gateway, etc. Otherwise, after a timeout of 20 seconds, the | |||
| unit will attempt to obtain an IP address by using AutoIP (IPv4 Dynamic Link Local Addressing). | |||
|
|
|
|
|
NOTE | The EX7000 can be returned to a known, default network configuration by using the LCI (LAN | |||
| Configuration Initialize) Mechanism. See Reset Button for more information. | |||
| AutoIP is a mechanism for finding an unused IP address in the IANA assigned range 169.254.X.Y | |||
| (169.254/16) where X is in the range 1 - 254 and Y is in the range 0 - 255. The device will first | |||
| attempt to obtain the specific address 169.254.X.Y, where X and Y are the | |||
| octets of the device’s MAC address. However, X will be set to 1 if it is 0 in the MAC address, and | |||
| to 254 if it is 255 in the MAC address for conformance with the AutoIP specifications. If this | |||
| address is already in use, the unit will attempt to obtain other IP addresses in the 169.254/16 range | |||
| in a pseudorandom fashion until it finds one that is available. | |||
| To illustrate the AutoIP mechanism, Table | |||
| MAC addresses. |

If a static IP address assignment is preferred, one can be optionally assigned via the embedded web page interface. This is done by clicking the Network Configuration link, disabling DHCP and AutoIP, enabling Static, and then assigning a static IP address, subnet mask, and gateway address, and, optionally, up to three DNS servers (see Figure
