Required Order of Components for Firmware Activation
If you upgrade firmware by individual components in a Cisco UCS domain, activate the updates in the required
order for quicker activation and to avoid potential issues with conflicting firmware versions.
Summary of Steps for Upgrading from Cisco UCS, Release 1.0(2) and Later
1
Download the following firmware images:
• Cisco UCS Infrastructure Software Bundle—Required for all Cisco UCS domains.
• Cisco UCS B-Series Blade Server Software Bundle—Required for all Cisco UCS domains that
include blade servers.
• Cisco UCS C-Series Rack-Mount Server Software Bundle—Only required for Cisco UCS domains
that include integrated rack-mount servers. This bundle contains firmware to enable Cisco UCS
Manager to manage those servers and is not applicable to standalone C-Series rack-mount servers.
2
(Optional) Disable Call Home—If the Cisco UCS domain includes Call Home or Smart Call Home, disable
Call Home to ensure you do not receive unnecessary alerts when Cisco UCS Manager restarts components.
3
Update adapters, /BMC, and IOMs—If you prefer, you can upgrade the adapters in a host firmware package
as part of the last upgrade step.
4
Activate adapters—Choose Ignore Compatibility Checkand Set Startup Version Only when performing
this step.
5
Activate /BMC—Choose Ignore Compatibility Check when performing this step.
6
Activate Cisco UCS Manager—Choose Ignore Compatibility Check when performing this step.
7
Activate I/O modules—Choose Ignore Compatibility Check and Set Startup Version Only when
performing this step.
8
Activate subordinate fabric interconnect—Choose Ignore Compatibility Check when performing this
step.
9
Activate primary fabric interconnect—Choose Ignore Compatibility Check when performing this step.
10
Update host firmware package(s) for servers—Must be the last firmware upgraded. We recommend that
you upgrade the board controller firmware during this step to avoid an additional reboot of servers with
that firmware. You must upgrade the following firmware in a host firmware package:
• BIOS
• Storage controller
• Certain adapters
11
(Optional) Enable Call Home—If you disabled Call Home before the upgrading the firmware, enable Call
Home.
