Problem of Powering On

Fail to power on the server
Is the server properly supplied with power?
Check if the power cord connects to the power outlet (or UPS) that meets the power specifications for
the server.
Use the power cord that comes with the server. Additionally, check the power cord for broken shield or
bent plugs.
Make sure the power 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 outputs power. Refer to the
manual that comes with the UPS for details.
Power supply to the server may be linked with UPS using the Setup Utility.
□ Have you pressed the POWER switch?
□ Is the STATUS LED indicator lit in green?
If the STATUS LED indicator is lit in red or amber, check the system status using the iLO, and also check
the connection of cables and optional items. If the problem persists, contact your maintenance service
company.
□ Is the window shown on the display?
Check the cable connection to the display and the power supply of the display.

appears.
