Transmit (XMIT): Indicates analyzer transmit activity (yellow). When the analyzer
is first powered on, it will generate transmit activity while trying to identify
devices on the network. Ping, Trace Route, Trace Switch Route, and Traffic
Generator will cause this LED to flash in proportion to the amount of transmit
activity.
Collision (COLSN): Indicates by yellow flashing intensity the amount of
Collisions being experienced on the network (yellow).
Error (ERROR): Indicates by red flashing intensity the amount of Errors being
experienced on the network (red). The Ethernet layer 2 error types include
Ethernet layer 2, CRC alignment, undersize, oversize, and jabber errors.

Connecting to the Network Under Test (NUT) Interface
Connect a patch cable to either the 10BASE-T/100BASE-TX, 100BASE-FX, or
1000BASE-X connector and connect the other end of the cable to any Ethernet
port in the network you want to test. This is considered the network under test
(NUT) connection.
Connecting to the Management Port
Use the Management port to manage the analyzer out of band when it is connected
to a different network (outside the network under test broadcast domain). In the
event that you are unable to communicate with the analyzer through the 10BASE-
T/100BASE-TX, 100BASE-FX, or 1000BASE-X (NUT) interface, you can use
the Management port to gain access to the analyzer.
The Management port is not a measurement interface. The Management port
facilitates remote control. Test functions such as traffic generation, cable testing
and active discovery only apply to the network under test interfaces (i.e.,
10/100BASE-T, 100BASE-FX, and 1000BASE-X). The Management port is also
used to flash new software into the analyzer. Note: Analyzer software updates can
only be done through the Management port.
