Figure 67. Removing the power supply unit
After you finish
1. Install a new power supply unit or install the power-supply filler to cover the power supply bay. See
“Install a power supply unit” on page 101.
Important: To ensure proper cooling during normal server operation, both of the power supply bays
must be occupied. This means that each bay must have a power supply unit installed; or one has a
power supply unit installed and the other has a power supply filler installed.
2. If you are instructed to return the component or optional device, follow all packaging instructions, and
use any packaging materials for shipping that are supplied to you.
