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:
1.
The cables for all external SCSI options are connected correctly.
2.
The last option in each SCSI chain, or the end of the SCSI cable, is terminated
correctly.
3.
All external SCSI options are turned on. You must turn on external SCSI options
before turning on the server.
If the problem remains, call for service.
Verify that:
1.
The power cables are properly connected to the server.
2.
The electrical outlet functions properly.
3.
The type of memory installed is correct.
4.
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.
5.
The LEDs on the power supply are on.
If the problem remains, call for service.
Verify if 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.
If the problem remains or if you are using an ACPI aware operating system, call for
service.
Verify that:
1.
Each port is assigned a unique address by the Configuration/Setup Utility
program and none of the serial ports are disabled.
2.
The serial-port adapter, if you installed one, is seated properly.
If the problem still exists, call for service.
Verify that:
1.
The device is compatible with the server.
