3. Insert the controller module into the chassis:
a. Ensure the latching mechanism arms are locked in the fully extended position.
b. Using both hands, align and gently slide the controller module into the latching mechanism arms until it
stops.
c. Place your index fingers through the finger holes from the inside of the latching mechanism.
d. Press your thumbs down on the orange tabs on top of the latching mechanism and gently push the
controller module over the stop.
e. Release your thumbs from the top of the latching mechanisms and continue pushing until the latching
mechanisms snap into place.
The controller module begins to boot as soon as it is fully seated in the chassis. Be prepared to
interrupt the boot process.
The controller module should be fully inserted and flush with the edges of the chassis.
4. Cable the management and console ports only, so that you can access the system to perform the tasks in
the following sections.
You will connect the rest of the cables to the controller module later in this procedure.
Step 5: Run diagnostics
After you have replaced a component in your system, you should run diagnostic tests on that component.
Your system must be at the LOADER prompt to start diagnostics.
All commands in the diagnostic procedures are issued from the controller where the component is being
replaced.
1. If the controller to be serviced is not at the LOADER prompt, reboot the controller:
system node halt
-node node_name
After you issue the command, you should wait until the system stops at the LOADER prompt.
2. At the LOADER prompt, access the special drivers specifically designed for system-level diagnostics to
function properly:
boot_diags
3. Select
Scan System
from the displayed menu to enable running the diagnostics tests.
4. Select
Test Memory
from the displayed menu.
5. Proceed based on the result of the preceding step:
◦
If the test failed, correct the failure, and then rerun the test.
◦
If the test reported no failures, select Reboot from the menu to reboot the system.
