For HA pairs with two controller modules in the same chassis, the sequence in which you install the controller
module is especially important because it attempts to reboot as soon as you completely seat it in the
chassis.

Step 1.
Align the end of the controller module with the opening in the chassis, and then gently push the
controller module halfway into the system.
Note: Do not completely insert the controller module in the chassis until instructed to do so.
Step 2.
Recable the console to the controller module, and then reconnect the management port.
Step 3.
Plug the power cables into the power supplies and reinstall the power cable retainers.
Step 4.
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.
Cross your arms and 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.
Step 5.
Repeat the preceding steps to install the second controller into the new chassis.
Running diagnostics
After you have replaced a component in your system, you should run diagnostic tests on that component.
B B e e f f o o r r e e y y o o u u b b e e g g i i n n
Your system must be at the LOADER prompt to start diagnostics.
A A b b o o u u t t t t h h i i s s t t a a s s k k
All commands in the diagnostic procedures are issued from the node where the component is being
replaced.
P P r r o o c c e e d d u u r r e e
Step 1.
If the node to be serviced is not at the LOADER prompt, reboot the node:
system node halt -node node_name
After you issue the command, you should wait until the system stops at the LOADER prompt.
Step 2.
At the LOADER prompt, access the special drivers specifically designed for system-level
diagnostics to function properly:
boot_diags
Step 3.
Select Scan System from the displayed menu to enable running the diagnostics tests.
Step 4.
Select Test system from the displayed menu to run diagnostics tests.
Step 5.
Proceed based on the result of the preceding step:
