■WhenStaticisvalid
IfStatic(xedaddress)isset,startupalwaysreliesupontheStaticcondition(xedaddress).
In such a case, DCHP/BOOTP, RARP, ARP/Ping become invalid, and startup does not occur.

initialized, operations follow this timing.
Note that there is an error of approximately ±3 in the times disclosed below.
* There are approximately 14 seconds from the time the power is turned on to the startup of the TCP/IP.

are outlined below.
 TheIPaddressacquiredrstbyeitherDCHPandBOOTPinthetimebetween0to15secondsisvalid.
When the IP address information is valid during that time, RARP and ARP/Ping do not start.

valid.
Addresses provided thereafter from another server are discarded.
When the IP address information is valid during that time, ARP/Ping do not start.

If this product is connected directly to an intelligent switch or intelligent hub, the physical link may take some time to become
established. In such cases, a timeout will occur while waiting to get the DHCP/BOOTP address, and it will fail to get the IP address.
In such cases, set DIPSW1 = ON to ignore the IP address acquisition timeout.
