Using the RESET Button
Pressing the RESET button resets the processor in the same manner as cycling power. You can
also use the RESET button to troubleshoot network connectivity.
The RESET button is located on the bottom of the controller.
1.
Hold the RESET button for 5 seconds, and then release it to boot the IC-3173 into safe
mode and enable Console Out.
2.
After booting the controller into safe mode, hold the RESET button again for 5 seconds to
enable IP reset, which resets the network adapter to its default configuration.
Safe Mode
When you boot the IC-3173 into safe mode, it launches only the services necessary for
updating its configuration and installing software. To resume normal operations, press the
RESET button for less than 5 seconds.
IP Reset
Use IP reset to reset the TCP/IP settings when moving the system from one subnet to another
or when the current TCP/IP settings are invalid.
When the IC-3173 is in the IP reset state, the IP address of the network port resets to DHCP or
a link-local address. You can then set up a new network configuration for the IC-3173 from a
development machine on the same subnet, or you can connect the IC-3173 directly to the
development computer.
Note
By default, the target automatically attempts to connect to the network using
DHCP. If the target is unable to initiate a DHCP connection, the target connects to
the network with a link-local IP address (169.254.x.x).
Replacing the Battery
The IC-3173 contains a user-replaceable battery. The battery compartment is located on the
left side of the device as you look at the device from the front. Take the following steps to
replace the battery:
Caution
Before removing the battery cover, disconnect all power connectors and
I/O cables from the device. To prevent damage from electrostatic discharge (ESD),
ground the unit and yourself by using a grounding strap or touching a grounded
object, such as a computer chassis.
