This section provides a procedure for troubleshooting the ports on the computer's I/O panel and the equipment connected to them, such as a printer, scanner, or other peripheral device. You can also use this procedure to test I/O ports on expansion cards. However, you should first complete the procedures in "Troubleshooting Expansion Cards" in Chapter 7 to verify that the card is configured and installed correctly. If a system error message indicates a port problem or if equipment connected to a port seems to perform incorrectly or not at all, the source of the problem may be any of the following: A faulty connection between the I/O port and the peripheral device A faulty cable between the I/O port and the peripheral device A faulty peripheral device Incorrect settings in the System Setup program Incorrect settings in the system's configuration files Faulty I/O port logic on the system board NOTE: With certain modems installed, subtests in the Serial Port Test Group may fail because the modem appears to the diagnostics as a serial port but it cannot be tested as a serial port. If you have a modem installed and you experience a serial-port test failure, remove the modem and run the diagnostic tests again. This procedure determines whether the computer's basic I/O functions are operational. If a system error message indicates an I/O port problem or the device connected to the port does not function properly, follow these steps: Are the communications ports set to Auto, and is Mouse set to Enabled? Yes. Go to step 3. No. Go to step 2. Is the problem resolved? Yes. You have fixed the problem. No. Go to step 3. 6-4 Dell PowerEdge 2300 Systems Installation and Troubleshooting Guide

Dell PowerEdge 2300 Systems Installation and Troubleshooting Guide
7URXEOHVKRRWLQJ±,À2±3RUWV
This section provides a procedure for troubleshooting the ports on the computer’s I/O
panel and the equipment connected to them, such as a printer, scanner, or other
peripheral device.
You can also use this procedure to test I/O ports on expansion cards. However, you
should first complete the procedures in “Troubleshooting Expansion Cards” in Chap-
ter 7 to verify that the card is configured and installed correctly.
If a system error message indicates a port problem or if equipment connected to a
port seems to perform incorrectly or not at all, the source of the problem may be any
of the following:
²
A faulty connection between the I/O port and the peripheral device
²
A faulty cable between the I/O port and the peripheral device
²
A faulty peripheral device
²
Incorrect settings in the System Setup program
²
Incorrect settings in the system’s configuration files
²
Faulty I/O port logic on the system board
NOTE: With certain modems installed, subtests in the Serial Port Test Group may fail
because the modem appears to the diagnostics as a serial port but it cannot be tested
as a serial port. If you have a modem installed and you experience a serial-port test
failure, remove the modem and run the diagnostic tests again.
