Prepare the Controller for Firmware Upgrade
1. It is important that the SNMP server is enabled before the firmware
upgrade begins. You can check if the SNMP server is enabled by looking at
the Channel Configuration page for Channel 1 in RSLogix 500/RSLogix
Micro. If the SNMP server is not enabled, you can still enable it in the
channel configuration page.
IMPORTANT
The user program is cleared as part of the operating system upgrade
process. You must restore your program after successfully loading the
operating system upgrade. The Ethernet communication configuration
parameters are retained and the SNMP is enabled by default after a
successful firmware upgrade.
IMPORTANT
A power cycle is needed in order for the changes in the Channel
Configuration page to be applied.
