1. Remove the screws from the chassis mount points.
2. With two people, slide the old chassis off the rack rails in a system cabinet or equipment rack, and then set
it aside.
3. If you are not already grounded, properly ground yourself.
4. Using two people, install the replacement chassis into the equipment rack or system cabinet by guiding the
chassis onto the rack rails in a system cabinet or equipment rack.
5. Slide the chassis all the way into the equipment rack or system cabinet.
6. Secure the front of the chassis to the equipment rack or system cabinet, using the screws you removed
from the old chassis.
7. If you have not already done so, install the bezel.
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.
Steps
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. Complete the installation of the controller module:
a. Plug the power cord into the power supply, reinstall the power cable locking collar, and then connect
the power supply to the power source.
b. Using the locking latches, firmly push the controller module into the chassis until the locking latches
begin to rise.
Do not use excessive force when sliding the controller module into the chassis to avoid
damaging the connectors.
c. Fully seat the controller module in the chassis by rotating the locking latches upward, tilting them so
that they clear the locking pins, gently push the controller all the way in, and then lower the locking
latches into the locked position.
The controller module begins to boot as soon as it is fully seated in the chassis. Be prepared to
interrupt the boot process.
d. If you have not already done so, reinstall the cable management device.
e. Interrupt the normal boot process and boot to LOADER by pressing
Ctrl-C
.
If your system stops at the boot menu, select the option to boot to LOADER.
