POST Progress and Error Reporting While POST is initialized, POST progress indications are visible when a TTY-type terminal or a tip line is connected between serial port A (default port) of the system being tested and a POST monitoring system. If an error occurs during execution, POST attempts to send a failure message to the POST monitoring system.
U1001, the motherboard, the power supply and the keyboard must be installed for POST to execute properly. Removing the optional system components and retesting the system isolates the possibility that those components are the cause of the failure. 3-22 Netra t 1120/1125 Service Manual • August 1998...
