What to do
Network collisions are bound to occur and are
normal. However, if this LED is lit solid, do the
following:
1 Check the physical network connection.
2 Verify that the Remote Office 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 There should be no broadcast or multicast
activity on the telephony LAN (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.
