We sell redundant power supplie's and fan's on HPe switches. We promise the customer that this will increase his uptime. If the first fan or power supply breaks down, PRTG does not notice this.
My request is that there is a warning when a power supply or fan fails.
PS We use the auto-discover function to add switches. There is an alternative way to do this but is very labor intensive and all Paessler customers with HPe switches need to do this.
