Questions about this item

How often should the internal fan be cleaned in this J9581A X311 400W unit?

Dust the fan intake every six to twelve months depending on the environment; a can of compressed air is sufficient and no disassembly is required.

What is the first limit reached when this 400W supply runs continuously at full load?

The 400 watt output ceiling is reached first; the unit will shut down or throttle if the connected ProCurve switch draws more than that sustained power.
