Interpreting the Reader Indicator LEDs
There are four LEDs on the reader indicating reader activity:

– When solid, the reader is booting. When pulsing, reader is ready for
operation.
Module A
– Operational only on older model Mercury4 readers.
Module B
– Flashes continuously when RF is transmitting on any antenna.
Fault/Error
– When solid red, the reader has crashed.
Two LEDs on top of the reader, labeled

and

, are not currently
operational. See the figure.
Two small LEDs adjacent to the Ethernet port indicate Status (left) and Activity (right)
when connected to a PC or network plug. See the figure.
