The test led command can be used in this case to check connectivity.
1. Run the test led port-network command on each administered port
network and verify that the LEDs on the correct port network are lit.
2. If they are not lit, check that the fiber connections to the port network are
consistent with the administered fibers (list fiber-link) that does not light
the LEDs as expected.
3. Run test led switch-node on each administered switch node carrier and
verify that the LEDs on the correct carrier are lit.
4. If they are not, check the connectivity to the switch node carrier that does
not light the LEDs as expected.
Incorrectly Connected Administered SNI-
to-SNI Fibers between Three Switch Nodes
If the system has more than 2 switch nodes, SNI-to-SNI fibers administered
between 2 switch nodes could be incorrectly connected to a third switch node.
This is a problem that could occur during installation or when inter-switch node
fibers are changed. For multiple fibers to a distant switch node, an incorrect
connection would not appear as a problem unless this fiber is used for a
system-link to a port network connected to the distant switch node. The status
sys-link command can be used to determine the boards and fiber links in the path
from an IPSI-connected EPN to a specific port network. A specific SNI-to-SNI
fiber connection must be in the system-link path to be checked with the port
network LED test.
One method to force an SNI-to-SNI fiber connection to be used as a system-link is
to physically remove every SNI-to-SNI connection except the fiber link being
tested at the distant switch node by physically removing SNI boards in the distant
switch node.
1. Use the status sys-link command to verify that this fiber selected for test
is in the path to the EPN connected to the distant switch node that will be
used for the LED test.
2. Run the test led sequence to a port network as described above to verify
this fiber connection.
3. Repeat this procedure for each of the other SNI-to-SNI fibers terminating
on this distant switch node.
Another method for testing multiple fiber connections to a distant switch node is
described below.
1. Use the list fiber-link command to determine the number of SNI-to-SNI
fibers that are administered to and terminating on this switch node.
2. Run the test led port-network command on an EPN connected to this
distant switch node, and verify that the LEDs on the correct EPN are lit.
