3-2 Sun Blade 150 Service Manual • June 2002
Note – Both POST and OpenBOOT PROM on Sun Blade 150 systems report the CPU
as an UltraSPARC IIe processor. The CPU in your system is an UltraSPARC IIi
processor.
3.2 How to Use POST
When the workstation power is applied, POST runs automatically if both of the
following conditions apply:
■ The diag-switch? NVRAM parameter is set to true.
■ The diag-level is set to either min or max.
In the event of an automatic workstation reset, POST runs if the diag-switch?
NVRAM parameter is set to true and the diag-level flag is set to either max or
min.
Note – If diag-switch = false, POST is disabled. If diag-switch = true and
diag-level = max, then POST runs in max mode. If diag-switch = true and
diag-level = min, then POST runs in min mode.
3.3 Pre-POST Preparation
To Prepare for POST you should:
■ Set up a terminal interface processor (TIP) connection to another workstation or
terminal to view POST progress and error messages. See Section 3.3.1, “Setting Up
a TIP Connection” on page 3-3.
■ Verify the baud rates between the tested workstation and another workstation
with a monitor, or a terminal display. See Section 3.3.3, “Verifying the Baud Rate”
on page 3-4.
