The Cisco UCS Manager software is at version 2.2(2c) or later.
The server is using BIOS/CIMC version 2.2(2c) or later.
The server is using the Intel E5-4600 v2 Series CPUs.
Blade Server Installation and Service Note
At this point, the Health LED of the server shows a critical fault and Cisco UCS Manager reports
a generic error message:
controller activation is required, as described in the next step.
In the Navigation pane, click the Equipment tab.
On the Equipment tab, expand Equipment > Chassis > Chassis number > Servers, then choose
your server.
In the Work pane, click the General tab.
In the Actions area, click Recover Server.
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.
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.
