Never pick up the SmartCell ZX-250r by the handles of its power supply.
When only one power supply is installed, a sheet metal blank MUST be installed in place of the missing power supply.
Failing to do so affects the fan’s air flow and may cause overheating and component failure. The blank also must be
installed to maintain EMI integrity.
