Step 4: Install the controller modules
After you install the controller modules into the new chassis, you need to boot it to a state
where you can run the diagnostic test.
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.
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.
Do not completely insert the controller module in the chassis until instructed to do so.
2. Recable the console to the controller module, and then reconnect the management port.
3. Plug the power cables into the power supplies and reinstall the power cable retainers.
4. Complete the reinstallation of the controller module:
a. Make sure the latch arms are locked in the extended position.
b. Using the latch arms, push the controller module into the chassis bay until it stops.
c. Press down and hold the orange tabs on top of the latching mechanism.
d. Gently push the controller module into the chassis bay until it is flush with the edges of the chassis.
The latching mechanism arms slide into the chassis.
The controller module begins to boot as soon as it is fully seated in the chassis.
e. Release the latches to lock the controller module into place.
f. Recable the power supply.
g. If you have not already done so, reinstall the cable management device.
h. Interrupt the normal boot process by pressing
Ctrl-C
.
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:
