5. Close the air duct.
Step 4: Reinstall the controller module and setting time/date after RTC battery
replacement
After you replace a component within the controller module, you must reinstall the
controller module in the system chassis, reset the time and date on the controller, and
then boot it.
You can use the following animation, illustration, or the written steps to install the controller module in the
chassis.
Installing the controller module
1. If you have not already done so, close the air duct or controller module cover.
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. If the power supplies were unplugged, plug them back in and reinstall the power cable retainers.
5. Complete the installation of the controller module:
a. Using the locking latches, 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.
