2.6.2 Installing SBB Power Supplies
Each SBB power supply has two green status LEDs. The upper LED indicates
AC power status and the lower LED indicates power supply status. The
procedure for installing power supplies is basically the same for installing any
SBB. Refer to Figure 2-23 during the installation.

1. Insert the SBB power supply 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 SBB power supply.
3. Turn on the AC input power 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 controller has failed, or the SBB power supply just installed
has failed.
