3.3.1 Identifying a Faulty Processor
1. Prepare the server module for service.
a. Power off both server module compute nodes.
See Section 2.4, “Powering Off the Server Module” on page 2-4 .
b. Remove the server module from the Sun Blade chassis. Place it on a flat
surface.
See Section 2.5, “Removing the Server Module From the Sun Blade Chassis” on
page 2-7 .
c. Attach an antistatic wrist strap.
See Section 2.6, “Performing Electrostatic Discharge and Antistatic Prevention
Measures” on page 2-9 .

Note –
Do not hold the Fault Remind button down longer than necessary.
A lit green charge status LED, located next to the Fault Remind button, indicates that
the fault remind LED circuit is operational. If the charge status LED is out, the fault
remind LEDs can not function. The charge status LED indicates the test circuit power
level. After the server module is inserted into the Sun Blade chassis, the test circuit
will recharge. However, the processor error(s) must re-occur to be stored and visible
on a fault LED during the next fault remind test.
A failed processor is identified by a lit processor fault LED. See
FIGURE 3-10
.
3. Identify which processor and heat sink you are replacing.
The numbering of the processors and corresponding processor fault LEDs on the
motherboard are shown in
FIGURE 3-10
