(2) MODE LED
(a) When turned off
Checking
Is the mode of the Ethernet adapter module set to Online?
If the above does not solve the problem, perform a unit test on the Ethernet adapter module to check for
hardware failure. ( Page 59, Section 6.3)
(b) When flashing
Checking
Is the mode of the master station set to Online?
Is the Ethernet adapter module in preparation for a unit test?
Is the Ethernet adapter module in execution of a unit test? (The
1 or 10 LED is flashing.)
If the above does not solve the problem, perform a unit test on the Ethernet adapter module to check for
hardware failure. ( Page 59, Section 6.3)
(3) D LINK LED
(a) When turned off
Checking
Is the Ethernet cable connected to PORT1 or PORT2 normal?
Are the other stations, where the Ethernet adapter module is
connected, normal?
Is the switching hub used in the system normal?
Does the network No. of the Ethernet adapter module match
that of the connected network?
If the above does not solve the problem, perform the following tests on the Ethernet adapter module to check
for failure.
• Unit test ( Page 59, Section 6.3)
• Cable test ( User's manual of the master/local module used)
Change the mode of the Ethernet adapter module to Online. ( Page
190, Section 10.3.2)
Change the mode of the master station to Online. ( User's manual for
the master/local module used)
If the switch on the Ethernet adapter module was repeatedly switched
between STOP and RESET/TEST, reset the Ethernet adapter module
and start the unit test.
The Ethernet adapter module is in execution of the unit test. Upon
termination of the test, the D LINK LED turns on. Take action according
to the test result. ( Page 59, Section 6.3)
• Check if Ethernet cables are used.
• Check if 1000BASE-T-compliant Ethernet cables are used. ( Page
49, Section 5.2.2 (1))
• Check if the station-to-station distance is 100m or less. ( Page 67,
Section 6.4.4 (7))
• Check if the cable laying (bend radius) is within the specified range.
( Manual for the Ethernet cable used)
• Check the Ethernet cables for disconnection.
Check if the other stations are powered on.
• Check if the switching hub is powered on.
• Check if a 1000BASE-T-compliant switching hub is used. ( Page
50, Section 5.2.2 (2))
Change the network No. of the Ethernet adapter module to that of the
connected network.
