LABEL DESCRIPTION
Port This is the port index number.
Active Select the check box to turn on the port. Clear it to disable the port.
Name Enter a descriptive name that identifies this port. You can use up to 31 ASCII
characters; spaces are not allowed.
Speed Mode Select the type of Ethernet connection for this port. When you don’t use auto-
negotiation, you must make sure that the settings of the peer Ethernet port are
the same in order to connect.
Select
Auto (auto-negotiation) to have the IES-1248 automatically determine
the type of connection that the Ethernet port has. When the peer Ethernet
device has auto-negotiation turned on, the IES-1248 negotiates with the peer to
determine the connection speed. If the peer Ethernet port does not have auto-
negotiation turned on, the IES-1248 determines the connection speed by
detecting the signal on the cable and using full duplex.
When an Ethernet port is set to
Auto , the IES-1248 tries to make a fiber
connection first and does not attempt to use the RJ-45 port if the fiber
connection is successful.
Select
100 Copper if the Ethernet port has a 100 MB electrical connection.
Select 1000 Copper if the Ethernet port has a 1000 MB (1 gigabit) electrical
connection.
Select
1000 Fiber if the Ethernet port has a 1000 MB (1 gigabit) fiber optic
connection.
Duplex The IES-1248 uses full duplex Ethernet connections by default.
