• Are all relevant switches and jumpers on the diskette drive set correctly?
• Is the diskette drive properly configured?
• Is the diskette drive activity light always on? If so, the signal cable may be
plugged in incorrectly.
If you are using the onboard diskette controller, use the BIOS setup to
make sure that “Onboard Floppy” is set to “Enabled.” If you are using
an add-in diskette controller, make sure that “Onboard Floppy” is set
to “Disabled.”

Check the following:
• Are the CD-ROM/DVD-ROM drive’s power and signal cables properly
installed?
• Are all relevant switches and jumpers on the drive set correctly?
• Is the drive properly configured?
Cannot Connect to a Server
• Make sure the network cable is securely attached to the correct connector
at the system back panel.
• Try a different network cable.
• Make sure you are using the correct and the current drivers.
• Make sure the driver is loaded and the protocols are bound.
• Make sure the hub port is configured for the same duplex mode as the
network controller.
• Make sure the correct networking software is installed.
• If you are directly connecting two servers (without a hub), you will need a
crossover cable.
• Check the network controller LEDs next to the NIC connectors.
Problems with Network
The server hangs when the drivers are loaded.
• Certain drivers may require interrupts that are not shared with other PCI
drivers. For these drivers, it may be necessary to alter settings so that
interrupts are not shared. See the documentation that came with your PCI
card(s) for information on changing interrupts.
Diagnostics pass but the connection fails.
