Netfinity 3500 - Miscellaneous Symptoms

Applicable to: World-Wide

Symptom

FRU/Action

CD-ROM drive not working properly.

1. Clean the CD
2. Clean the optical-headv lens
3. CD-ROM Drive

CD-ROM drive tray is not working.
(See CD-ROM Emergency Eject on page 16 .)

1. CD-ROM Drive

Server does not recognize the CD-ROM drive.

1. Verify that the CD-ROM drive is enabled in the Configuration/Setup Utility program.
2. Verify that the server is checking for the CD-ROM drive in the startup sequence. Use the Configuration/Setup Utility program.
3. CD
4. CD-ROM Drive

CD-ROM drive in-use light stays on, or the system continues to bypass the CD-ROM drive.

1. CD-ROM

Diskette drive in-use light stays on, or the system bypasses the diskette drive.

1. Verify that the diskette drive is enabled in the Configuration/Setup Utility program.
2. Verify that a know good diskette is properly inserted in the
drive
3. The diskette contains the necessary files to start the system
4. Diskette Drive

General monitor problems. Some IBM monitors have their own self-tests. If you suspect a problem with your monitor, refer to the information that comes with the monitor for adjusting and testing instructions.

1. Monitor

The screen is blank.

1. Check power cord and cable connections.
2. Monitor
3. Video Adapter

Only the cursor appears.

1. Video Adapter

The monitor goes blank when some application programs start.

1. Check all cable connections.
2. Verify that the graphics adapter is correctly installed in
slot 1, the Accelerated Graphics Port (AGP).
3. Verify that the device drivers necessary for the applications are installed.

The monitor works when you power-on the system, but goes blank after some period of server inactivity.
Note
The Advanced Power Management (APM) feature is not
supported.

1. If enabled, disable the Advanced Power Management (APM) feature setting in the Configuration/Setup Utility program.

Screen flickers.
Attention
Using a resolution or refresh rate that is not supported by the
monitor might damage it.

1. Set monitor to highest, noninterlaced refresh rate supported by the monitor and controller.
2. Monitor
3. Video Adapter

Wavy, unreadable, rolling, distorted screen, or screen jitter.
If the monitor self-tests show that the monitor is working properly, verify that:
1. Check the location of the Monitor.
2. Verify that an IBM monitor signal cable is properly connected.
3. Verify that the monitor is not trying to run at a higher refresh rate than supported.

1. Monitor
2. Video Adapter

Wrong characters appear on the screen.

1. Video Adapter Cable
2. Video Adapter

The server does not start when you press the power switch.
Before replacing a FRU:
1. Check all cable connections.
2. Verify that the server cover is properly installed.
3. Verify that the power outlet functions properly.
4. Verify that the correct type of memory is installed.

1. Power Switch/LED Assembly
2. Power Supply

An IBM option that used to work does not work now.
Notes
1. If the option comes with its own test instructions, use those instructions to test the option.
2. An external option must be powered-on prior to powering-on the system.

1. Check all cable connections.
2. For SCSI options, check for proper termination.
3. Option Device

The parallel port cannot be accessed, or the number of
parallel ports displayed is less than the number of parallel ports installed.
See Serial/Parallel/USB Port Problems on page 46 .

1. Device
2. Adapter, if installed
3. System Board

The serial port cannot be accessed, or the number of serial ports displayed is less than the number of serial ports installed.
See Serial/Parallel/USB Port Problems on page 46 .

1. Device
2. Adapter, if installed
3. System Board

Serial port and USB port problems.
See Serial/Parallel/USB Port Problems on page 46 .

1. Device
2. Adapter, if installed
3. System Board

The SCSI expansion enclosure used to work, but does not work now.

1. Verify that all SCSI expansion enclosure hardware and cable connections are secure.
2. Verify termination of the last option in each SCSI chain, or the end of the SCSI cable.
3. If the SCSI expansion enclosure comes with its own test
instructions, use those instructions to test it.
4. SCSI Repeater Card

The SCSI Repeater Card used to work, but does not work now.

1. Verify that all SCSI Repeater Card hardware and cable
connections are secure.
2. Verify that all external SCSI option cables are connected correctly.
3. Verify the termination of the last option in each SCSI chain, or the end of the SCSI cable.
4. SCSI Repeater Card

The Ethernet Adapter cannot connect to the network.
See "Ethernet Connection Problems" on page 34 .

1. Ethernet Adapter

The Configuration/Setup Utility program reports the Ethernet controller interrupt Utility as 0 or 255.
The PCI BIOS is not configuring the Ethernet controller or adapter correctly.

1. The PCI BIOS interrupt settings are incorrect. Check for
interrupt conflicts with ISA devices. If conflicts are found,
reserve the ISA interrupts (see "ISA Legacy Resources"
on page 27) so that the PCI BIOS will assign another
non-conflicting PCI interrupt value.

The Configuration/Setup Utility program reports No PCI Bus.
The Configuration/Setup Utility program has been run on another computer that does not have any PCI slots.

1. Run the Configuration/Setup Utility program on the server so that the PCI BIOS will configure the Ethernet controller or
adapter correctly

The server stops running when loading device drivers.
The PCI BIOS interrupt settings are incorrect.

1. Check for interrupt conflicts with ISA devices. If conflicts
are found, reserve the ISA interrupts (see "ISA Legacy
Resources" on page 27) so that the PCI BIOS will assign
another non-conflicting PCI interrupt value.

The diagnostics completed successfully, but the network connection fails.

1. Make sure that the network cable is securely attached.
2. Make sure that you are using Category 5 cabling when operating the server at either 10 Mbps or 100 Mbps.

The Ethernet Activity light does not come on.

1. Make sure the network device drivers are loaded.
2. Check all connections.
3. Try sending data from this workstation.
4. Use another Ethernet adapter (see "Installing or Removing Adapters" on page 51).
5. Use another port on the hub.
6. Make sure that the hub port is configured for the correct speed (10 Mbps or 100 Mbps).
7. If duplex mode was forced, make sure a speed of 10 Mbps or 100 Mbps was forced.
8. If you manually configured the duplex mode, make sure that you also manually configured the speed.
9. Ethernet Adapter

Data is incorrect or sporadic.

1. Make sure that you are using Category 5 cabling when
operating the server at either 10 Mbps or 100 Mbps.

The Ethernet controller or adapter stopped working when another adapter was added to the server.

1. Make sure that the cable is connected to the Ethernet adapter.
2. Make sure that your PCI system BIOS is current.
3. Reseat the adapter.
4. Ethernet Adapter

The Ethernet controller or adapter stopped working without apparent cause.

1. Reseat the adapter.
2. Try a different connector at the hub or switch.
3. The network device driver files might be missing or corrupted;
4. Ethernet Adapter
