F5 appliance LCD warning displays cannot be seen remotely, neither LED alarms. But if you would like to remotely see any warnings, these are written in /var/log/ltm file.
However you can remotely clear LCD warnings and Alarm LED using following commands.
Note: Performing following procedure should not have a negative impact on the appliance.
lcdwarn -c <level> <slotid>
In this command syntax, note the following:
<level> specifies the alert level to be cleared, specify either [0|1|2|3|4|5] or [warning|error|alert|critical|emergency|information]
<slotid>, leave as 0 for non-VIPRION platform.
For example,
To clear LCD warnings
[root@F5LB:Active:In Sync] config # lcdwarn -c 0 0
To clear errors
[root@F5LB:Active:In Sync] config # lcdwarn -c 1 0
If you would like to clear all the LCD warnings
[root@F5LB:Active:In Sync] config # for i in 0 1 2 3 4 5; do lcdwarn -c “${i}” 0; done
