There should be no water in the header drain pan and the drain pan should always remain dry.
Some amount of condensation water can always be expected in the heat exchanger drain pans. If an
excessive amount of condensation water accumulates in a drain pan, an alarm is triggered and sent through
the HP POD 20c ECS, indicating a possible leak.
For more information on leak detection, see the HP Performance Optimized Datacenter 20c Maintenance
and Service Guide.
