A corporate workstation has been suffering frequent power supply unit (PSU) failures. After reviewing the setup, a technician notes that the workstations are connected to a 220-240 VAC outlet, but the PSUs are configured manually for a 110-120 VAC input. What should the technician do to correct this issue and prevent future PSU failures?
Check the wattage rating on the power supply units.
Switch the PSU voltage input selector to 220-240 VAC.
Install an automatic voltage regulator for each workstation.
Ensure there is proper ventilation around the power supply units.
For the PSU to function correctly without damage, the technician must manually switch the PSU voltage input selector from 110-120 VAC to 220-240 VAC to match the electrical outlet specification. Power supply units with a manual voltage selector can be adjusted to suit the local power grid voltage; failure to set the correct input voltage can result in PSU damage. Configuring the workstations with an automatic voltage regulator would not alter the required PSU input settings. Checking the wattage rating is important for overall power requirements but does not relate directly to the voltage input issue described. While ensuring proper ventilation is generally good practice, it is not the root cause of the failures based on the information provided.
