If the mouse is damaged, continue to the next step.
Swap the faulty mouse with a working mouse.
If the problem is resolved, replace the faulty mouse. See "Getting Help."
Enter the System Setup program and ensure that the USB ports are enabled. See "Using the
System Setup Program" in your User's Guide.
If the problem is not resolved, see "Getting Help."
Troubleshooting Basic I/O Functions
Problem
Error message indicates a problem with a serial port.
Device connected to a serial port is not operating properly.
Action
Enter the System Setup program and ensure that the serial port(s) is enabled. See "Using the
System Setup Program" in the User's Guide.
If the problem is confined to a particular application, see the application documentation for
specific port configuration requirements that the program may require.
Check the appropriate indicator on the NIC connector. See "NIC Indicator Codes" in
"Indicators, Messages, and Codes."
If the link indicator does not light, check all cable connections.
If the activity indicator does not light, the network driver files might be damaged or missing. Ensure that the appropriate drivers are installed and the protocols are bound. See the NIC's documentation.
Remove and reinstall the drivers if applicable. See the NIC's documentation.
Change the autonegotiation setting, if possible.
Use another connector on the switch or hub.
If you are using a NIC card instead of an integrated NIC, see the documentation for the NIC card.
Enter the System Setup program and confirm that the NIC is enabled. See "Using the System
Setup Program" in your User's Guide.
Ensure that the NICs, hubs, and switches on the network are all set to the same data
transmission speed. See the network equipment documentation.
Ensure that all network cables are of the proper type and do not exceed the maximum length.
See "Network Cable Requirements" in "I/O Connectors."

Inside the System
In Figure 4-2, the system cover is opened to provide an interior view of the system.
Figure 4-2. Inside the System
The system board can accommodate one processor, five expansion cards (two 5-V, half-length 32-bit, 33-MHz PCI, one 2.5-Gb/sec PCIe [x1], one 2.5-Gb/sec PCIe [x4], and one 2.5-Gb/sec PCIe [x8]), and four 533-MHz unbuffered ECC DDR II single or dual-rank memory modules.
The drive bays provide space for up to two 1-inch SATA hard drives with the integrated SATA controller or two SCSI hard drives. The SCSI hard drives must be connected to a controller card. They also provide space for an optional optical and diskette drive, or an optional tape backup unit (TBU). Power is supplied to the system board and internal peripherals through a single nonredundant power supply.
Removing and Replacing the Front Drive Bezel

Before performing any procedure, see your Product Information Guide for complete information about safety precautions, working inside the computer and protecting against electrostatic discharge.
System message indicates a problem with the battery.
System Setup program loses system configuration information.
System date and time do not remain current.
NOTE: If the system is turned off for long periods of time (for weeks or months), the NVRAM may lose its system configuration information. This situation is caused by a defective battery.
A coin-cell battery maintains system configuration, date, and time information. The battery can last several years. If you have to repeatedly reset time and date information after turning on the system, or the following messages appear, replace the battery. See "Replacing the Battery" in "Installing System Options."
Time-of-day not set - please run SETUP program
or
Invalid configuration information - please run SETUP program
or
Battery voltage is low
You can operate your system without a battery; however, without a battery, the configuration information is erased if the system is turned off or unplugged from the electrical outlet. In this case, you must enter the System Setup program and reset the configuration options.
CAUTION: A new battery can explode if it is incorrectly installed. Replace the battery only with the same or equivalent type recommended by the manufacturer. Discard used batteries according to the manufacturer's instructions.
Action
Re-enter the time and date through the System Setup program. See "Using the System Setup
Program" in your User's Guide.
Turn off the system and disconnect it from the electrical outlet for at least one hour.
Reconnect the system to the electrical outlet and turn on the system.
Enter the System Setup program.
If the date and time are not correct in the System Setup program, replace the battery. See "System Battery" in "Installing System Options."
If the problem is not resolved by replacing the battery, see "Getting Help."
NOTE: Some software may cause the system time to speed up or slow down. If the system seems to operate normally except for the time kept in the System Setup program, the problem may be caused by software rather than by a defective battery.
Troubleshooting Power Supplies
Problem
Power-supply fault indicator is blinking amber.
Action
CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. Before performing any procedure, see your Product Information Guide for complete information about safety precautions, working inside the computer and protecting against electrostatic discharge.

If the AUX_PWR_LED indicator is lit, the power supply is good. Proceed to the next step.
If the AUX_PWR_LED indicator is not lit, remove the faulty power supply and see "Removing the Power Supply" in "Installing System Options."
Check that the voltage selection switch on the back panel of the system is set properly. See
"Power Supply Features" in "Indicators, Messages, and Codes."
NOTICE: Setting the voltage selection switch to an improper setting can damage your system.
Ensure that the power supply is properly installed by removing and reinstalling it. See
"Installing the Power Supply" in "Installing System Options."
NOTE: After installing a power supply, allow several seconds for the system to recognize the power supply and to determine if it is working properly. The power indicator turns green to signify that the power supply is functioning properly.
System message indicates a fan-related error message.
Action
CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. Before performing any procedure, see your Product Information Guide for complete information about safety precautions, working inside the computer and protecting against electrostatic discharge.
