Chapter 7: Troubleshooting
Your 56K modem does not connect at 56K
Current FCC regulations restrict actual data transfer rates over public telephone lines to
53K. Other factors, such as line noise, telephone service provider equipment, or ISP
limitations, may lower the speed even further.
If your system has a v.90 modem, the speed at which you can upload (send) data is limited
to 33.6K. If your system has a v.92 modem, the speed at which you can upload data is
limited to 48K. Your ISP may not support 48K uploads.
The modem is not recognized by your server
■
If the modem shares the telephone line with another device, make sure that the
telephone line is not in use (for example, someone is on the telephone, or another
modem is in use).
■
Shut down and restart your server.
■
Reinstall the modem device driver. For more information, see Using Your System
Companion CD .
■ Open your server and reseat the modem. For more information, see “Installing PCI
expansion cards” on page 69 .
Monitor
Your server is running but there is no picture
■
Adjust the brightness and contrast controls to the center position.
■
Make sure that the monitor is plugged in and turned on. If the monitor is turned
on, the power LED should be lit.
■
Check the port and cable for bent or damaged pins.
■ Connect your monitor to another computer, or connect a monitor that you know
works to your server.
The color is not uniform
Make sure that the monitor warms up for at least 30 minutes before making a final
judgment about color uniformity.
Make sure that:
■
The monitor is not positioned too close to another monitor, electric fan, or
fluorescent light.
■ You demagnetize the screen using the monitor’s degauss feature. For more
information on degauss, see the monitor’s documentation.
