Installation Problems Perform the following checks when you troubleshoot installation problems: Check all cable and power connections (including all rack cable connections). Unplug the power cord and wait for one minute. Then reconnect the power cord and try again. If the network is reporting an error, verify that the system has enough memory and disk space. Remove all added peripherals, one at a time, and try to turn on the system. If after removing a peripheral the system works, it may be a problem with the peripheral or a configuration problem between the peripheral and the system. Contact the peripheral vendor for assistance. If the system does not power on, check the LED display. If the power LED is not on, you may not be receiving AC power. Check the AC power cord to make sure that it is securely connected. Troubleshooting System Startup Failure If your system halts during startup, especially after installing an operating system or reconfiguring your system's hardware, check for invalid memory configurations. These could cause the system to halt at startup without any video output. For all other startup issues, note any system messages that appear onscreen. See "Using the System Setup Program" on page 65 for more information. Troubleshooting External Connections Ensure that all external cables are securely attached to the external connectors on your system before troubleshooting any external devices. See Figure 1-1 to Figure 1-6, and Figure 1-14, Figure 1-15 for the front- and back-panel connectors on your system. 290 | Troubleshooting Your System
