1.	Check the OK LED. The OK LED is located on the front of the Sun Blade		Section 2.3, “Interpreting
		T6320 server module.	System LEDs” on page 2-12
		If the LED is not lit, check that the blade is properly
		connected and the chassis has power.

2.Type the ILOM show /SP/faultmgmt command to check for faults.

The faultmgmt command displays the following types of faults:

•Environmental faults

•Solaris Predictive Self-Healing (PSH) detected faults

•POST detected faults

Faulty FRUs are identified in fault messages using the FRU name. For a list of FRU names, see TABLE 1-3.

Section 2.5.3, “Displaying System Faults” on

page 2-21
