This chapter contains the following topics: Section 3.1 “POST Overview” on page 3-1 Section 3.2 “Pre-POST Preparation” on page 3-2 Section 3.3 “Initializing POST” on page 3-5 Section 3.4 “Bypassing POST”...
Page 40: How To Use Post
If a terminal or a monitor is not connected to serial port A (default port) of a system or server to be tested, the keyboard LEDs are used to determine error conditions. See Section 3.7 “System and Keyboard LEDs” on page 3-41. Sun Ultra 80 Service Manual • March 2000...
Page 41: Setting Up A Tip Connection
3.2.1 Setting Up a Tip Connection A tip connection enables a remote shell window to be used as a terminal to display test data from a system. Serial port A or serial port B of a tested system is used to establish the tip connection between the system being tested and another Sun system monitor or TTY-type terminal.
Page 42: Verifying The Baud Rate
3. Verify the following serial port default settings as follows: ttyb-mode = 9600,8,n,1 ttya-mode = 9600,8,n,1 Note – Ensure that the settings are consistent with TTY-type terminal or system monitor settings. Sun Ultra 80 Service Manual • March 2000...
Page 43: Initializing Post
Initializing POST You can initialize POST in two ways: Set the diag-switch? to true and the diag-level to max or min, and then power cycle the system Simultaneously press the Stop and D keyboard keys while power is applied to the system To set the diag-switch? to true and power cycle the system: 1.
Page 44: Bypassing Post
Examples of the min-level POST output on serial port A is provided in Section 3.5.2 “diag-level Variable Set to min” on page 3-28. To set the diag-level variable to min, type: ok setenv diag-level min Sun Ultra 80 Service Manual • March 2000...
Page 45: Diag-Level Variable Set To Max
To return to the default setting: ok setenv diag-level max 3.5.1 diag-level Variable Set to max When the diag-level variable is set to max, POST enables an extended set of diagnostic-level tests. The following code examples identify a typical serial port A POST output with the diag-level variable set to max for 4-way, 2-way, and single CPU configurations.
