The CK722 Network Utility Tool (NUT) is a troubleshooting tool that allows you to restore
functionality to the CK722 network controller in the event of device failure, and upgrade the
controller’s operating system, by deleting the data from the unit and re-installing the
controller’s operating system (OS) and firmware. Once you re-install the firmware and OS,
the controller’s configuration settings will be re-initialized with the factory default settings.
Downloading the CK722 object database from the P2000AE SCT returns the controller’s
settings to their desired configuration.
This document describes how to use the Network Utility Tool (NUT) to install the CK722
controller’s OS and firmware.
I
MPORTANT
The Network Utility Tool should only be used on new CK722 controllers,
when the CK722 is unresponsive and requires drastic measures to get the
unit up and running, or when you need to update the controller’s operating
system. Do
not use the Network Utility Tool to update the CK722 firmware
if the unit is functioning properly and does not require an operating system
update.
To update the firmware for a properly functioning controller, use the P2000
Host software’s firmware update feature. Refer to the P2000AE Software
User Manual for details.
Using the Network Utility Tool to install the CK722 OS and firmware can take 15 minutes,
plus any setup and breakdown time.
