System board internal cable connectors
The following illustration identifies system board connectors for cable connectors.
Move the mouse over the index number in the illustration below. Click the index number to locate the description.
System board external port connectors
The following illustration identifies system board connectors for external devices.
Move the mouse over the index number in the illustration below. Click the index number to locate the description.
| Index | Description |
|---|---|
| 1 | Parallel port (J22) |
| 2 | Video/Advanced System Management Processor port (J13) |
| 3 | USB ports (J11) |
| 4 | Ethernet ports (J9) |
| 5 | Keyboard/mouse port (J6) |
| 6 | Serial ports (J3) |
System board jumpers and switches
The following illustration identifies the switches and jumpers on the system board.
Move the mouse over the index number in the illustration below. Click the index number to locate the description.
| Index | Description |
|---|---|
| 1 | Boot block jumper (J37) |
NOTE: System board switch block (SW1) can be found at the bottom right of the diagram above.
System board switch block
The switch block contains microswitches 1-8. Switch 8 is at the top of the switch block and switch 1 is at the bottom. The following table describes the function for each switch.
| Switch number | Switch description |
|---|---|
| 1 | Microprocessor speed setting (requires switches 1-4). |
| 2 | Microprocessor speed setting (requires switches 1-4). |
| 3 | Microprocessor speed setting (requires switches 1-4). |
| 4 | Microprocessor speed setting (requires switches 1-4). |
| 5 | Power-on override. The default setting is Off (disabled). When On, overrides the power-on switch and forces power-on mode. The system will always boot without the use of the power-on switch. |
| 6 | Clock frequency selection. The default setting is Off. When On, sets the host bus speed to 100 MHz. When Off, the host bus speed is 133 MHz. |
| 7 | Reserved. The default setting is Off. |
| 8 | Bypass power-on password. The default setting is Off. When On, bypass the power-on password. When Off, require the user to enter the power-on password at startup, if one is set. |
Microprocessor speed settings
| Microprocessor speed | Switch 1 | Switch 2 | Switch 3 | Switch 4 |
|---|---|---|---|---|
| 667MHz/133Mz | On | On | Off | Off |
| 733MHz/133Mz | On | Off | Off | Off |
| 800MHz/133Mz | Off | On | On | On |
| 866MHz/133Mz | Off | Off | On | On |
| 933MHz/133Mz | Off | On | Off | On |
NOTE: The speed settings shown above apply only to unlocked processors. If the processors are production level they are locked and there is no need to change the speed settings.
System board LED locations
The following illustration identifies system board LEDs. You may need to refer to this diagram when troubleshooting a problem.
Move the mouse over the index number in the illustration below. Click the index number to locate the description.
Diagnostic panel LEDs
| LED | Description |
|---|---|
| PS1 | Power supply 1 failure. |
| PS2 | Power supply 2 failure. |
| PS3 | Power supply 3 failure. |
| NON | Non-redundant power. |
| OVER | Overspecification. The system has exceeded the power capabilities of the installed power supply units. |
| NMI | Non-maskable-interrupt occurred. |
| Temp | System temperature exceeded maximum rating. |
| FAN | A fan failed or is operating slowly. |
| MEM | Memory failure. One or more memory DIMMS have failed. |
| CPU | Microprocessor failure. One or both microprocessors have failed. |
| PCI 1 | Error on primary PCI channel (A) or system board. |
| PCI 2 | Error on secondary PCI channel (B) or system board. |
| VRM | Error on voltage regulator module or on integrated voltage regulator. |
| DASD 1 | The hot-swap disk drive backplane on SCSI channel A has failed. |
| DASD 2 | Not used. |
