  • Page 46: Post Overview

    POST is useful in determining if a portion of the system has failed and should be replaced. POST detects approximately 85 percent of Ultra 2 series system faults and is located in the system board OpenBoot PROM (OBP). The setting of the diag-level switch determines the POST function.

  • Page 47: Setting Up A Tip Connection

    OBP. To set up a tip connection: 1. Connect serial port A of the system being tested to another Sun Workstation serial port B using a serial null modem cable (connect cable pins 2-3, 3-2, 7-20, and 20-7).

  • Page 48: Verifying The Baud Rate

    4. In a shell tool window on the Sun Workstation, enter tip hardwire. The system replies: hostname% tip hardwire connected Note – The shell window is now a tip window directed to the serial port of the Sun Workstation or server being tested. When power is applied to the system being tested, POST messages will be displayed in this window.

  • Page 49: Initilizing Post

    1. At the system prompt, enter: setenv diag-switch? true. Verify the prompt, diag-switch? true, is displayed 2. At the Sun type-5 keyboard, power cycle the system by simultaneously pressing the shift key and the power-on key (Figure 2-1). After a few seconds, press the power-on key.

Additional POST progress indications are also visible when a TTY-type terminal or a tip line is connected between serial port B (default port) of the system being tested and a POST monitoring system.

  • Page 59: Bypassing Post

    POST may be disabled and thereby bypassed. To bypass POST: 1. Prior to powering on the system, press and hold the Stop and D keys on the Sun type-5 keyboard. 2. With the Stop and D keys pressed, turn on the system by pressing the power-on key (Figure 2-1 on page 2-6).
