Troubleshooting Using Indicators
Section 10-1
Troubleshooting with LNK and M/A Indicators
Data Link Cannot be Started
The following table describes the LNK and M/A indicators at the startup node
and their use in troubleshooting when a data link cannot be started.
Starting a data link depends on the Controller Link Unit operating normally
and participating in the Network. Refer to Troubleshooting with RUN, ERC,
ERH and INS Indicators earlier in this section and check Unit operation before
using the following table.

Cables are not
connected cor-
rectly.
Check the cable
connections are
reconnect cor-
rectly.
The node address
is larger than the
maximum node
address set in the
network parame-
ters.
Either change the
maximum node
address setting
with the Controller
Link Support Soft-
ware (Ver. 2.00 or
higher) or set a
node address
below the maxi-
mum.
No other nodes
exist.
Make sure that 2 or
more nodes exist
within the Network.
No node has been
set as the polling
node.
Refer to 9-1-2 Set-
ting the Polling and
Polled Nodes and
set the Controller
Link Unit as the
polling node.
(If both types of
optical Units are
used in a network,
use the Optical
Ring Units as
polled nodes.)
The transmission
path format setting
is different in the
polling node.
Change the set-
ting to match the
one in the polling
node and turn the
power ON again.
