Make sure that: v The device is compatible with the computer. v The serial port is enabled and is assigned a unique address. v The device is connected to the correct connector, (see "System-board external connectors" in the Problem Determination and Service Guide). 2. Reseat the failing serial device. 3. Replace the following components one at a time, in the order shown, restarting the computer each time: a. Failing serial device b. (Trained service technician only) System board Software problems v Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved. v See the parts listing in the Problem Determination and Service Guide to determine which components are customer replaceable units (CRU) and which components are field replaceable units (FRU). v If an action step is preceded by "(Trained service technician only)," that step must be performed only by a trained service technician. Symptom Action A suspected software problem occurred. 1. To determine whether the problem is caused by the software, make sure that: v The computer has the minimum memory that is needed to use the software.
