PoE General Status Format
The PoE General Status front panel display item contains the following status definitions:
PoE Not Available
- The system is not being powered from an AC source.
OK: xx.xW
- No general faults are present, where xx.x is the total power in watts currently being provided on
the PoE ports.
Max Power Exceeded
- The total power drawn on the ports is greater than the PoE power capacity.
Voltage Fault
- The PoE voltage is out of range.
PoE Port Status
If the system is not being powered from an AC source, the status will read "
PoE Not Available
". Otherwise, the status
consists of four subfields separated by blanks, each of the format
x:cc
, where
x
is the port number (1, 2, 3, or 4) and
cc
is
the condition code. If there is not a fault on the port, the possible condition codes are as follows:
N
- No device is attached on the port or the device is not a PoE Powered Device.
L
- A PoE Powered Device of Class 1 or 2 is attached on the port.
M
- A PoE Powered Device of Class 0 or 3 is attached on the port.
H
- A PoE Powered Device of Class 4 is attached on the port.
D
- The port has been disabled.
ED
- A PoE Powered Device is attached on the port, but the load has been disconnected due to not drawing at
least minimum current.
EO
- A PoE Powered Device is attached on the port, but has been shut off due to drawing more than
maximum current or due to overheating on the controller's port.

LEDs
This section details the various LEDs on the front panel of the NX-series controllers.
General Status LEDs
The General Status LEDs include the Link/Activity, Status, Output, and Input LEDs. These LEDs appear on all models
of NX-series controllers.
FIG. 12 displays the General Status LEDs for each NX-series controller.
FIG. 12
General Status LEDs
Link/Act - Lights green when the link is up and toggles off when a data packet is sent or received.
Status - Lights green and blinks once per second if the master is functioning normally and has established
communication with a DHCP server.
Input - Lights yellow when the controller receives data
Output - Lights red when the controller transmits data
