retain configuration settings. Make sure the SNMP Write Lock switch is set to the
LOCKED position. Save the PROM file periodically in case there is a need to replace
the SNMP management module.
If the management module is removed with the SNMP Write Lock switch set to
NORMAL, all settings for the modules revert to those established by hardware
switches. Configure the hardware settings to match those made via SNMP. Installing
the SAME management module once again will return the application modules to
management control and any settings previously established via software. Installing a
new management module when the SNMP Write Lock switch is set to NORMAL will
cause installed application modules to revert to default settings. Always reconfigure
application modules when moving them from one chassis to another.
Using the SNMP Write Lock Switch
1. Ensure the SNMP Write Lock switch is set to NORMAL.
2. After configuring all application module settings via SNMP, use the iConfig
application to make a backup copy of the SNMP management board's
firmware.
The first two steps are typically performed during initial installation.
3. If the SNMP management module needs exchanging, first set the SNMP
Write Lock switch to LOCKED.
4. Remove the old SNMP module and replace with another SNMP module.
5. Connect to this SNMP module via iView², and then launch iConfig.
6. Select the Administration tab and click on List Tasks.
7. Highlight Flashsav and then click on the Terminate button.
8. Update the new board with the firmware backup made in Step 2.
9. Reboot the SNMP management module with the reboot command to
enable changes.
10. After rebooting, set the SNMP Write Lock switch back to NORMAL.
If removing an SNMP card with the SNMP Write Lock enabled (set to
LOCKED), current application module settings will not be changed.
Never power-cycle the chassis while the SNMP Write Lock is enabled.
This reverts the SNMP card back to its original, factory settings.
iView² should only be accessed with the SNMP Write Lock disabled.
The previously made settings to the application modules are now active.
