What to do
Network collisions are bound to occur and
are normal. However, if this LED indicator is
lit solid, do the following:
1 Check the physical network connection.
2 Verify that the Remote Gateway 9150
unit can be pinged.
3 Check the network configuration (such
as routing, traffic load, and so on). Adjust
the network configuration, if required.
4 Normally there is no broadcast or
multicast activity on the TLAN.
Interconnect a hub and a network
analyzer to the TLAN and monitor for
such activity. Identify the source(s) and
isolate them from the TLAN.
1 Ensure that the Remote Gateway 9150
unit is powered up. The Remote
Gateway 9150 unit cannot send or
receive traffic if it is not powered up.
2 Check the Ethernet cable between the
Remote Gateway 9150 unit and the
network, and ensure that it is good.
3 Ensure the Ethernet cable is connected.
4 If the Remote Gateway 9150 unit still will
not send or receive traffic, contact your
data network administrator.
5 Data network administrator: Ensure that
other network devices are configured to
allow traffic to and from the Remote
Gateway 9150 unit.
It is possible that communication has been
lost between the administration PC and the
Remote Gateway 9150 unit.
Close Configuration Manager, and then
restart it.
