Verify that:
v The option is designed for the server. See the "Server Support" flowchart for
information about obtaining ServerProven
World Wide Web.
v You followed the installation instructions that came with the option.
v The option is installed correctly.
v You have not loosened any other installed options or cables.
v You updated the configuration information in the Configuration/Setup Utility
program. Whenever memory or an option is changed, you must update the
configuration.
If the problem remains, call for service.
Verify that all of the option hardware and cable connections are secure.
If the option comes with its own test instructions, use those instructions to test the
option.
If the failing option is a SCSI option, verify that:
v The cables for all external SCSI options are connected correctly.
v The last option in each SCSI chain, or the end of the SCSI cable, is terminated
correctly.
v Any external SCSI option is turned on. You must turn on an external SCSI option
before turning on the server.
If the problem remains, call for service.
Verify that:
v The power cords are properly connected to the server.
v The electrical outlet functions properly.
v The type of memory installed is correct.
v If you just installed an option, remove it, and restart the server. If the server now
turns on, you might have installed more options than the power supply supports.
If the problem remains, call for service.
Verify whether you are using an ACPI or non-ACPI operating system.
If you are using a non-ACPI operating system:
1. Press Ctrl+Alt+Delete.
2. Turn off the system by using the power-control button. You might need to press
and hold the power-control button for 5 seconds to force the server to turn off.
If the problem remains or if you are using an ACPI-aware operating system, call for
service.
