What Next

Verify correct operation of the power supply by checking the fan and LED indicators on the rear of the supply. The fan should start spinning and both LEDs should light within three seconds of completing a hot-plug installation (or after restoring power to the system).

For more information, see:

• "Power Supply LEDs"

The power supply retains its last power on/off state once it is removed from the system. If you remove a power supply from a system that is powered off and attempt a hot-plug installation into a system that is powered on, the power supply will remain off. To activate the power supply, turn the front panel keyswitch from the Power-On position to the Diagnostics position, and then back to the Power-On position. Alternatively, you may press the Power-On key on a Sun Type-5 keyboard attached to the system. For descriptions of the various keyswitch settings, see "About the Status and Control Panel".
