NETWORK CONFIGURATION

The EX7000-OEM Network Configuration page can be seen in Figure 4-5. By default, the

EX7000-OEM will 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-OEM 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 second-to-last and last

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.
