Overview

Firmware upgrades in Intersight include server firmware upgrades and infrastructure firmware upgrades. Infrastructure firmware upgrades in Intersight Managed mode is supported on Cisco UCS Fabric Interconnects Series 6600, 6500, 6400, and Cisco UCS X-Series Direct Fabric Interconnects. To manage the Cisco UCS infrastructure firmware, see Upgrading Fabric Interconnect Firmware in IMM. This feature is available with a Cisco Intersight Essentials or Advanced license tier.

In Intersight, infrastructure and server firmware upgrades can be done independently. That is, you do not need to upgrade infrastructure firmware to use the latest server firmware and vice versa. For more information on compatibility between infrastructure firmware and server firmware, see Cross Version Firmware Support. For more information on server firmware updates, see Release Notes for Cisco Intersight Managed Mode Server Firmware.
