Troubleshooting Server Does Not Power Off NOTE If the server is off, and power is not connected to server power supplies, pressing the power button has no effect. Power problems during installation are usually related to the installation process. If the server does not power on, check the LED indicators on the power supply rear panels and follow these steps. • If the AC In indicators are lit, it is assumed that power is available to the server. • If a fault indicator is lit, reseat the power supply. If the problem persists, remove and reseat boards within the server. If the problem persists, replace the power supply or the power supply interface board. • If the AC Out indicators are lit, it is assumed that power is available to the server circuits. If the console shows that the server is powered on, but server LEDs indicate that power is off, remove and reseat connectors on the LED status board. If the problem persists, replace the LED status board. If the console shows that the server is not powered on (server is off), remove and reseat connectors on the system board. If the problem persists, replace the power supply interface board, the MP board, or the system board. See the HP Integrity rx2620 User Service Guide for more information.
