Settings and Commands
Ethernet Network Operation Settings
The SEL-2701 operates over either twisted-pair or fiber-optic media. Each
SEL-2701 is equipped with two network ports. With an initial ordering option,
you can select the media for each port (10/100 Mbps twisted-pair, 10 Mbps
fiber-optic, or 100 Mbps fiber-optic). Speeds for the physical media are fixed
for fiber-optic connections. For twisted-pair connections, the SEL-2701 can
auto-detect the network speed or you can set a fixed speed.
Network Port
Fail-Over Operation
The SEL-2701 has two network ports. Network port fail-over mode enables
the SEL-2701 to operate as a single network adapter with a primary and
standby physical interface. You can connect the two network ports to the same
network or different networks depending on your specific Ethernet network
architecture. If you have a single network and want to use only one network
port, set NETPORT to the port you wish to use and set FAILOVR to N.
Only one network port operates at a time. The fail-over mode operation
determines the active port. To use fail-over mode, follow the steps listed
below:
Step 1. Set NETPORT to the preferred network interface.
Step 2. Set FAILOVR to Y.
Step 3. Set FTIME to the desired network port fail-over time.
