Chapter 6 LEDs and DIP Switches
The initialization scrolling pattern will last longer than usual if the smart camera is configured
to acquire an IP address from a DHCP server but no DHCP server is available on the network.
When acquiring an IP address from a DHCP server, the smart camera waits up to 60 seconds to
acquire an IP address. If the smart camera does not receive an IP address within 60 seconds, the
device automatically restarts and tries again. The smart camera attempts to acquire an IP address
from a DHCP server three times. If after the third time the smart camera has not been assigned
an IP address, the smart camera reverts to the unconfigured state and the IP address resets to
0.0.0.0
. The STATUS LED flashes to indicate that the smart camera is in an unconfigured
state.
POWER LED
The POWER LED indicates whether the power supplied to the camera is adequate. The POWER
LED is green while the camera is properly powered on. When no power is being supplied to the
NI Smart Camera, the POWER
LED is unlit. When power is first applied to the smart camera,
the POWER LED flashes red for one second while internal systems power up. If the POWER
LED stays red for longer than one second, it indicates that the voltage is out of range.
STATUS LED
The STATUS LED is green during normal operation. The NI Smart Camera indicates specific
conditions by flashing the STATUS LED, as shown in Table 6-1.
Table 6-1.

Color Indication
Solid Green The smart camera initialized successfully and is ready for use.
1 Flash Green The smart camera IP address or software is unconfigured. The
smart camera ships from the factory unconfigured. The smart
camera also enters the unconfigured state if it is configured for
DHCP and no DHCP server is available. Use MAX or Vision
Builder AI to configure the smart camera. Refer to
Getting
Started with the NI 17xx Smart Camera
for information about
configuring the smart camera.
2 Flashes Green The smart camera detects an error in the software
configuration. The camera has automatically started up into
safe mode, regardless of the SAFE MODE DIP switch position.
This usually occurs when an attempt to upgrade the software is
interrupted or if system files are deleted from the smart camera.
Reinstall software on the smart camera. Refer to
Getting
Started with the NI 17xx Smart Camera
for information about
installing software on the smart camera.
