Is the server properly supplied with power?
Check if the power cord is connected to a power outlet (or UPS) that meets the power
specifications for the server.
Make sure to use the power cord provided with the server. Check the power cord for broken
shield or bent plugs.
Make sure the circuit breaker for the connected power outlet is on.
If the power cord is plugged to a UPS, make sure the UPS is powered and it supplies power.
Refer to the manual that comes with the UPS for details.
In addition, be sure to check the power interlock function with the UPS by using BIOS Setup
Utility.
