Troubleshooting DR Devices
The following table details possible causes and solutions if your DR is not functioning properly. If you
detect a problem with a DR, we recommend first checking the HAL to determine if the problem is orig-
inating there.

Possible Causes
Suggested Action
A flashing
P
appears in the
upper left corner, indicating
the DR is not receiving
enough power.
The HAL is not powered.
Power on the HAL.
A mis-wired or broken cable is dis-
rupting power to the DR.
Use a cable tester to verify
CAT 5 termination.
If using a punch block, verify
that the brown pair is prop-
erly punched. (Assuming
T568B termination).
The cable is not plugged into a
HAL.
Plugging the DR cable into
some other device (like an
Ethernet switch) will not
supply power to the DR.
The CAT 5 cable between the DR
and the HAL is too long.
Shorten the cable!
There is excessive voltage drop
between the HAL and DR.
Verify it is 24 AWG (or
heavier) cable.
Verify the cable length from
HAL to DR has not
exceeded 150 meters.
A spinning wheel and the
words

never
go away.
The twisted pair in the CAT 5 cable
that carries communications data is
mis-wired or broken.
Use a cable tester to verify
the wiring of the CAT 5
cable.
If using a punch block, verify
that the orange pair is prop-
erly punched (assuming
T568B termination).
A flashing exclamation
point and the words
Con-
figuration Mismatch
.
The physical DR model detected on
the port does not match the con-
figured model for that port.
See Resolving a Device Mis-
match.
A flashing
L
appears in the
upper right corner
The DR is in Locate mode.
End Locate mode for that DR
from within Halogen.
