Name Type Status Description
LINK/TR
LED: Green or
Orange
Indicates the
operating status of
the Ethernet port.
#6
Green: A link is established.
Blinking green: A frame is being sent
or received.
Orange: A failure has been detected.
Off: A link failure occurred
#3 #4
or
operation has stopped.
#3 #5
#1: A network interface unit can be turned off by the Inactivate operation from the
system operation panel or by entering a command from the operation terminal.
#2: If no system recovery is set, the network interface unit is turned off in the
following situations:
z When a failure occurred in the network interface unit (the STATUS LED turns
red, and then it turns off).
z When a failure occurred in a basic control unit (when the basic control unit is
not duplicated).
#3: When the STATUS LED is green.
#4: Cable disconnection is also included.
#5: Operation of an Ethernet port can be stopped by entering a command from the
operation terminal.
#6: Always turns off if the interface port LED is set to off. When an operation key on
the system operation panel is used, the LED lights up, and the operating status can
be checked. If no keys are used for 60 seconds, the LED turns off again.
NOTE
If no system recovery is set and a failure occurs in a Switch, the
Switch can stay stopped without recovering the failed part.
(3) NK1GS-8M
The NK1GS-8M is a network interface unit with the following hardware
specifications:
z Ethernet port (10/100/1000BASE-T): 4 ports
z Ethernet port (1000BASE-X): 8 ports
NOTE
You cannot use 10/100/1000BASE-T and 1000BASE-X at the same
time because 10/100/1000BASE-T and 1000BASE-X share ports 1 to
4 of this network interface mechanism. Edit the configuration to set
either 10/100/1000BASE-T or 1000BASE-X for each port. (By default,
1000BASE-X is set for ports 1 to 4.)
For details about editing the configuration, see the software manual.
NOTE
For information about the SFP transceivers supported by the Switch,
see 1.8.1 SFP.
