3. Plug the power cables into the power supplies and reinstall the power cable retainers.
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. 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.
5. Repeat the preceding steps to install the second controller into the new chassis.

Step 1: Verify and set the HA state of the chassis
You must verify the HA state of the chassis, and, if necessary, update the state to match
your system configuration.
1. In Maintenance mode, from either controller module, display the HA state of the local controller module and
chassis:
ha-config show
The HA state should be the same for all components.
2. If the displayed system state for the chassis does not match your system configuration:
a.
Set the HA state for the chassis:
ha-config modify chassis HA-state
The value for HA-state can be one of the following:
â–ª
ha
â–ª
mcc
â–ª
mccip
â–ª
non-ha
b.
Confirm that the setting has changed:
ha-config show
3. If you have not already done so, recable the rest of your system.
4. Reinstall the bezel on the front of the system.
Step 2: Run diagnostics
After you have replaced a component in your system, you should run diagnostic tests on
that component.
