Table 24. Error symptoms and suggested actions (continued)
An IBM option that was just
installed does not work.
1. Verify that:
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.
2. Option you just installed.
An IBM option that used to
work does not work now.
1. Verify that all of the option hardware and cable connections are secure.
2. If the option comes with its own test instructions, use those instructions to test
the option.
3. 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 engine.

Power problems
Symptom
Part/action
The engine does not turn on.
1. Verify that:
v
The power cables are properly connected to the engine.
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 engine. If the engine
now turns on, you might have installed more options than the power supply
supports.
2. If LEDs for CPUs or VRMs are on, verify that:
a. A VRM is populated for each microprocessor.
b. Override front panel pushbutton by turning on switch 7 of SW1; if power
comes on:
1) Service processor error.
2) Power reset card.
3. See “Undetermined problems” on page 151.
The engine does not turn off.
1. Verify whether you are using an ACPI or non-ACPI operating system. If you are
using a non-ACPI operating system:
a. Press Ctrl+Alt+Delete.
b. Turn off the system by holding the power-control button for 4 seconds.
c. If engine fails during BIOS POST and power-control button does not work,
remove the AC power cord.
2. If the problem remains or if you are using an ACPI-aware operating system,
suspect the system board.
Serial port problems
Symptom
Part/action
The number of serial ports
identified by the operating
system is less than the number
of serial ports installed.
1. Verify that:
v
Each port is assigned a unique address by the Configuration/Setup Utility
program and none of the serial ports is disabled.
v
The serial-port adapter, if you installed one, is seated properly.
2. Failing serial port adapter.
