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.

Ge n e r a l S t a t u s L E D s
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
The following table lists the following special LED patterns for the Status, Input, and Output LEDs:
* - The fast blink is nearly instantaneous upon downloading the boot firmware to Flash memory and is, in most cases, undetectable
to the user’s eye.
