Server Does Not Power On
The server Power button on the front panel operates differently depending on how long the button
is held in, and on what the system is doing when the button is pressed. You must be aware of its
uses to properly troubleshoot the system.
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.
