Step 3 Replace the Intel E5-2400 v2 Series CPUs with the earlier supported CPUs.
Use the procedures in the Blade Server Installation and Service Note for your server.
Step 4 Reinsert the server to the chassis.
Step 5 Wait for Cisco UCS Manager to automatically discover the server.
Note At this point, the Health LED of the server shows a critical fault and Cisco UCS Manager reports
a generic error message: WILL_BOOT_FAULT: Sensor failure asserted. This is because a board
controller activation is required, as described in the next step.
Step 6 Perform a board controller activation by using the Cisco UCS Manager CLI interface. Use the following
sequence of commands:
Note The server automatically reboots after the commit-buffer command is executed.
Note The show image command in the sequence below lists the board controller versions available for
the server. Always activate the latest board controller image version when you use the
activate firmware command.
# scope server <chassis/server>
# scope boardcontroller
# show image
# activate firmware <boardcontroller version>.0 force
# commit-buffer
See also Sample Board Controller Activation Command Sequence, page 18.
Step 7 Do not continue with the next step until the board controller activation completes. Verify whether the
activation is complete by using the show version command.
As shown in the example below, wait until the Activate-Status returns Ready. This process takes a few
minutes before Activate-status is successfully completed and returns Ready.
# show version

Step 8 Clear the WILL_BOOT_FAULT by using the Cisco UCS Manager GUI to reset the server CIMC:
a. In the Navigation pane, click the Equipment tab.
b. On the Equipment tab, expand Equipment > Chassis > Chassis number > Servers, then choose
your server.
c. In the Work pane, click the General tab.
d. In the Actions area, click Recover Server.
e. In the Recover Server dialog, click Reset CIMC (Server Controller), then click OK.
Wait for CIMC to reboot and for Cisco UCS Manager to do a shallow discovery of the server. This
takes two to three minutes. At the end of this process the WILL_BOOT_FAULT is cleared.
Note The Cisco UCS Manager 2.2(2c) bundle, including the server CIMC and BIOS, is
backward-compatible with earlier supported CPUs, so the following firmware downgrade steps
are optional.
Step 9 Optional: Downgrade your server CIMC.
Use the GUI or CLI procedures in the UCS Manager Install and Upgrade Guides.
Step 10 Optional: Downgrade your server BIOS.
Use the GUI or CLI procedures in the UCS Manager Install and Upgrade Guides.
