There are several LEDs on the NION front panel that help indicate unit status.
Fault |
|
RED |
Audio not working. |
OFF |
Audio working. |
The Fault LED tracks the state of the fault relay. (The fault relay signals appear on pins of the GPIO connector.)
Note: The RED state does not necessarily indicate a problem, but that audio is not actively being processed and passed. This state occurs normally when the unit is rebooting or has not yet been configured to run a Project. It also occurs when the unit has encountered a problem and can no longer process and pass audio.
X-DAB |
|
GREEN |
Primary and backup rings are operational. |
YELLOW OR GREEN BLINKING |
Running in backup with single cable missing - all audio present. |
YELLOW/RED OR RED BLINKING |
Running in backup mode with multiple cables/nodes missing - some audio gone. |
RED |
Failure - some or all audio gone. Not running in backup mode. |
OFF |
XDAB is not in use (in the current Project/Role for this NioNode). |
Note: The XDAB LED is updated only when XDAB is used by the NioNode in the current Project and the NioNode is up and passing audio.
LAN |
|
GREEN |
Ethernet link. |
OFF |
No Ethernet Link. |
CobraNET |
|
GREEN |
Ethernet link. |
GREEN BLINKING |
Ethernet link and NioNode is CobraNet Conductor. |
RED |
No link or CM-1 missing or malfunctioning, and NION is configured to use CM-1. |
OFF |
No link or CM-1 missing or malfunctioning, and NION is not configured to use CM-1. |
Note: Even if the NION has not been configured to use its CM-1 (in the project design), link and Conductor status are still reported and the unit will be visible as a CobraNet node on the network it is attached to. You will only a red CobraNET LED if the NION has been configured to use its CM-1 and there is a problem with the link or the CM-1 module.
IDE |
|
GREEN |
Mass storage (CompactFlash) read or write activity. |
OFF |
No activity. |
Tip: The IDE LED indicator is remarkably similar to the disk status LED you may have on the front of your PC or on the bezel of your laptop.
Attn |
|
RED BLINKING |
Indicates there is an error or warning condition of interest. |
OFF |
No status change of interest. |
Tip: This indicator is paired with a button. When the LED blinks, the button can be pressed to cause the LCD to navigate to a page displaying the source of the condition.
Attn |
|
OFF |
Unit is off. |
ORANGE |
Unit is booting up or down. |
GREEN |
Unit has booted up. |
