SEL-2701 Ethernet Processor Instruction Manual
Several settings control how the SEL-2701 operates on an Ethernet network.
These settings include IP addressing information, network port fail-over
options, and network speed.
Use the network configuration settings shown in
SEL-2701 for operation on an IP network and to set other parameters affecting
the physical Ethernet network interface operation. See
page xv in Preface for the proper format of an IP address.

Table 3.1 SEL-2701 Network Configuration Settings

Label Description
IPADDR IP network address
SUBNETM IP network subnet mask
DEFRTR Default router
NETPORT Primary network port
(D disables all network ports)
FAILOVR Automatic fail-over enable
FTIME Fail-over time out
a
NETASPD Network speed or
auto-detect on Port A
a
NETBSPD Network speed or
auto-detect on Port B
a
This setting applies only to twisted-pair ports (10/100BASE-T).
The SEL-2701 uses the IPADDR and SUBNETM settings to determine the
local network and SEL-2701 node address. The SUBNETM setting defines
the subnet mask. The subnet mask divides the local node IP address into two
parts, a network number and a node address on that network. A subnet mask is
four bytes of information and is expressed in the same format as an IP address.
The SEL-2701 uses the DEFRTR address setting to determine how to
communicate with nodes on other local networks. The SEL-2701
communicates with the default router to send data to nodes on other local
networks. If you change the DEFRTR setting from the default value of Null
(meaning that there is no default router), then the default router must be on the
same local network as the SEL-2701 or the SEL-2701 will reject the DEFRTR
setting. You must also coordinate the default router with your general network
implementation and administration plan. See
examples of how IPADDR and SUBNETM define the network and node and
how these settings affect the DEFRTR setting.
