1. Insert the power supply SBB into the guide slots and push in until the power supply is
fully seated and the mounting tabs are engaged into the shelf.
2. Connect the power cord to the power supply SBB.
3. Turn on the ac input power entry controller.
4. Observe the power supply SBB LEDs. Both LEDs should be lit, indicating proper
power supply operation on the associated bus.
5. If the upper LED is not lit after installation this indicates that the power supply is not
functioning properly and needs to be replaced. If both status LEDs are not lit after the
installation, either there is a lack of ac power, the ac input power entry controller has
failed, or the power supply SBB just installed has failed.
