6 To install a second power supply, repeat steps 3 through 5.
NOTE
If power supplies are not installed in both power supply bays, be sure to install a cover over the
unoccupied bay. Unoccupied bays must always be covered to maintain proper system ventilation and EMI levels.
7 Connect the AC power cord to the input connector on the power supply. Then connect the cord to an
AC power outlet.
WARNING!
Always be sure that the source outlet is properly grounded before plugging the AC power cord into the
AC power supply.
