2.3.3 Alarm and Status Indicators
TXD
When lit GREEN, indicates transmitted data into the wireless link.
RXD
When lit GREEN, indicates received data from the far end of the wireless link.
COLL
This is an alarm. When lit RED, indicates that Ethernet collisions are occurring.
These collisions may be normal for a heavily used WAN, but should be remedied as
soon as possible as the maximum throughput of the radio link is not being realized.
It is normal for the COLL indicator to blink occasionally.
BER
This is the Bit Error Rate (BER) alarm. When lit RED, this alarm condition indicates
that the received signal bit error rate is above the error threshold of 1 x 10
-
6
. This
alarm condition typically indicates a path problem or a problem with the far-end radio
and usually is not a problem with the near- end radio.
SYNC
When lit RED, this is an alarm condition indicating that the intended received signal
is not being received. This alarm may indicate problems related to the path,
connections, or the near-end or far-end radio hardware.
MUTE
When lit RED, this is an alarm condition indicates that one or both of the following:
1) The security address setting for switch 2 on the back of the radio does not
match the radio bridge on the other end of the link.
2) There is an excessive number of data errors on the 10BaseT connection that the
radio will not transmit so it MUTEs (or BLOCKS) the data from being sent.
FAN
When lit RED, this is an alarm condition indicating a failure with one or both of the
internal cooling fans. The radio is designed to operate within specification when only
one fan is operating. The two fans are provided for redundancy only.
RADIO
FAIL
When lit RED, this is an alarm condition indicating a major failure with the near-end
radio hardware.
FAR END
When lit RED, this is an alarm condition indicating that there are alarm or status
conditions present on the far-end radio. Press and hold the "Display Far End" button
on the near-end radios to indicate the alarm conditions for the far-end radio terminal.
Monitoring the far-end alarms can be helpful for radio installation and routine
maintenance.
