2. 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.
3. Recable the system, as needed.
If you removed the media converters (QSFPs or SFPs), remember to reinstall them if you are using fiber
optic cables.
4. Plug the power cord into the power supply, reinstall the power cable locking collar, and then connect the
power supply to the power source.
5. Complete the reinstallation of the controller module:
a. Firmly push the controller module into the chassis until it meets the midplane and is fully seated.
The locking latches rise when the controller module is fully seated.
Do not use excessive force when sliding the controller module into the chassis to avoid
damaging the connectors.
The controller module begins to boot as soon as it is fully seated in the chassis. Be prepared to
interrupt the boot process.
b. Rotate the locking latches upward, tilting them so that they clear the locking pins, and then lower them
into the locked position.
c. If you have not already done so, reinstall the cable management device.
d. Interrupt the normal boot process by pressing
Ctrl-C
.
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 node where the component is being replaced.
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.
2. At the LOADER prompt, access the special drivers specifically designed for system-level diagnostics to
function properly:
