2.2(5)

Low-Level Firmware Requirements

Note You will be directed to this section from the upgrade procedures only for cases in which you are not using the Cisco Host Upgrade Utility or Cisco UCS Manager to upgrade the server firmware.

Low-level server firmware controls server components such as the power sequencer, field-programmable gate arrays (FPGAs), and power supply units (PSUs).

Note The low-level firmware must be up-to-date before you upgrade the CPU hardware.

If you update the server BIOS and Cisco IMC management firmware by using the Cisco Host Upgrade Utility (HUU) or the Cisco UCS Manager as directed in these procedures, the low-level firmware is updated automatically. If you use any other method such as the Cisco IMC interface, you must manually initiate the low-level firmware update.

- Initiating a Low-Level Firmware Update Using the Cisco IMC GUI interface

- Initiating a Low-Level Firmware Update Using the Cisco IMC CLI interface

Initiating a Low-Level Firmware Update Using the Cisco IMC GUI interface

Step 1 Log into the GUI interface for the server by using a browser and the IP address that was assigned to the server.

Step 2 If not already powered on, power on the server by using the GUI interface.

Step 3 Power off the server by using the GUI interface.

- If the server’s low-level firmware is not up-to-date, a dialog appears with the following message:

- If you do not see this dialog, all components are up-to-date and no further update is required.

to initiate the low-level firmware update.

When the low-level firmware update is finished, you can continue with replacing the hardware.

Initiating a Low-Level Firmware Update Using the Cisco IMC CLI interface

Step 1 Log in to the CLI interface for the server.

Step 2 Enter the following commands and observe the message that is returned:

# scope chassis/firmware

/chassis/firmware # show detail

- If the return is Firmware update not required, all components are up to date , skip to Step 4.

- If the return is Firmware update required on some components, please run update-all , continue with the following step.

Step 3 Enter the following command:

/chassis/firmware # update-all

Starting firmware update process, this will take a while. Check status using show command.

Step 4 When the update is done, enter the following commands:

/chassis/firmware # exit

/chassis # exit

The following is an example of these commands used in an update operation.

# scope chassis/firmware

/chassis/firmware # show detail

Firmware update required on some components, please run update-all (under chassis/firmware scope).

/chassis/firmware # update-all

Starting firmware update process, this will take a while. Check status using show command

/chassis/firmware # show detail

Firmware update process is running, retry to get latest status.

...

/chassis/firmware # show detail

Firmware update completed

/chassis/firmware # show detail

Firmware update not required, all components are up to date

/chassis/firmware # exit

/chassis # exit

Upgrading to Intel Xeon v3 Series CPUs

Note These upgrade procedures require server downtime.

This section contains the following topics:

- Upgrade Scenario 1: UCSM-Managed C-Series Server

- Upgrade Scenario 2: Standalone Server

- Upgrade Scenario 3: Standalone Server RMA; BIOS on Spare Server is Earlier Than the Minimum Version

Upgrade Scenario 1: UCSM-Managed C-Series Server

This scenario assumes the following conditions:

- The server is managed by Cisco UCS Manager.

- The Cisco UCS Manager software is earlier than the minimum (see Minimum Software and Firmware Requirements).

- The C server is at a BIOS/Cisco IMC version earlier than the minimum (see Minimum Software and Firmware Requirements).

- The server is using CPUs earlier than Intel Xeon v3 Series.

- The server is using DDR3 memory risers and DIMMs.

In this case, use the following procedure to upgrade the server, CPUs, memory risers, and DIMMs.

.

.

.

for your release.

Note If you use a method other than Cisco UCS Manager to update the integrated server’s Cisco IMC firmware, you must also manually initiate a low-level firmware upgrade. See Low-Level Firmware Requirements.

.

for your release.

Step 4 Decommission and then power off the server.

Step 5 Replace the CPUs with the Intel Xeon v3 Series CPUs.

.

Step 6 Replace all the DDR3 memory risers and DIMMs in the server with new DDR4 memory risers and DIMMs.

.

Step 7 Power on the server.

Step 8 Wait for Cisco UCS Manager to automatically discover and associate the server.

Upgrade Scenario 2: Standalone Server

This scenario assumes the following conditions:

- The server is in standalone mode.

- The server is at a BIOS/Cisco IMC version earlier than the minimum (see Minimum Software and Firmware Requirements).

- The server is using CPUs earlier than Intel Xeon v3 Series.

- The server is using DDR3 memory risers and DIMMs.

In this case, use the following procedure to upgrade the server, CPUs, memory risers, and DIMMs.

Step 1 Use the Cisco Host Upgrade Utility (HUU) to upgrade and activate the server Cisco IMC and BIOS to the minimum version for your server (or later).

for your minimum release (or later) to download and use the utility package.

Caution Be sure to update the Cisco IMC and BIOS when you select which components to update. The Cisco HUU ensures that the firmware is matched. The server will not boot if the Cisco IMC and BIOS become mismatched.

Note If you use a method other than the Cisco Host Upgrade Utility to update the standalone server’s Cisco IMC firmware, you must also manually initiate a low-level firmware upgrade. See Low-Level Firmware Requirements.

Step 2 Power off the server.

Step 3 Replace the CPUs with the Intel Xeon v3 Series CPUs.

.

Step 4 Replace all the DDR3 memory risers and DIMMs in the server with new DDR4 memory risers and DIMMs.

.

Step 5 Power on the server.

Upgrade Scenario 3: Standalone Server RMA; BIOS on Spare Server is Earlier Than the Minimum Version

This scenario is unique to a field-service situation in which a server that is already running Intel Xeon v3 Series CPUs must be replaced (RMA), but the only replacement server available is running a BIOS earlier than the minimum version.

This scenario assumes the following conditions:

- The server is in standalone mode.

- The replacement server is using Intel Xeon v3 Series CPUs (after the CPUs are transferred from the defective server).

- The replacement server is using DDR4 DIMMs and DDR4 memory risers (after the DIMMs and memory risers are transferred from the defective server).

- The replacement server is using BIOS/Cisco IMC version earlier than the minimum version for your server (see Minimum Software and Firmware Requirements).

Use the following procedure to upgrade the replacement server BIOS to the required version:

Step 1 After you transfer the Intel Xeon v3 Series CPUs, DDR4 DIMMs, and DDR4 memory risers from the defective server to the replacement server, power on the replacement server.

Note The server does not boot because the BIOS is an earlier version than that required for the new CPUs and memory.

The Cisco Host Upgrade Utility (HUU) that is normally recommended for upgrading the Cisco IMC and BIOS cannot be used when the CPUs are non-bootable. However, the HUU ISO image contains a Zip file that has the images required for updating the server through a browser. Continue with the following steps to upgrade the server BIOS to the minimum version for your server (or later) by using a browser.

Step 2 Download the HUU ISO file for your minimum release (or later) from Cisco.com and save it on a laptop or other computer.

for your release.

Step 3 Mount the ISO image.

Step 4 Extract the Zip file that is contained within the ISO image.

Note To determine the IP address of the target server so that you can log in to its Cisco IMC, you must connect the server to a DHCP-enabled network, as described in the next step.

Step 5 Determine the IP address of the target server that you are upgrading:

a. Look at the physical MAC address label for the dedicated management port or the LOM1 port, depending on which port is enabled by default in the target server.

b. Connect an Ethernet cable for your DHCP-enabled network to the dedicated management port or the LOM 1 port.

Your DHCP server assigns an IP address to the port.

c. Query your DHCP server based on the MAC address of the port that you connected. The IP address of the port that corresponds to the MAC address is listed.

Step 6 Use the Cisco IMC GUI in a browser to log in as administrator on the IP address of the target server.

Step 7 Use the Cisco IMC GUI to install and activate the Cisco IMC minimum version for your server (or later).

.

Caution When you install new BIOS firmware, it must be from the same software release as the Cisco IMC firmware running on the server. Do not install new BIOS firmware until after you have activated the matching Cisco IMC firmware or the server will not boot.

Step 8 While logged in as administrator, use the Cisco IMC GUI to install the BIOS minimum version for your server (or later).

.

Note If you use a method other than the Cisco Host Upgrade Utility to update the standalone server’s Cisco IMC firmware, you must also manually initiate a low-level firmware upgrade. See Low-Level Firmware Requirements.

Use the following procedure to downgrade to earlier supported CPUs, memory risers, and DIMMs.

Step 1 Power off the server.

Step 2 Replace the Intel Xeon v3 Series CPUs with the earlier supported CPUs.

.

Step 3 Replace the DDR4 memory risers and DIMMs with the earlier supported DDR3 memory risers and DIMMs.

.

Step 4 Power on the server.

Note The Cisco IMC bundle, including the server Cisco IMC and BIOS, is backward-compatible with earlier supported CPUs, so the following firmware downgrade steps are optional.

Step 5 Optional: Downgrade your server Cisco IMC.

.

Step 6 Optional: Downgrade your server BIOS.

TPM 2.0 Considerations

Trusted platform module (TPM) version 2.0 is supported on Intel v3- or Intel v4-based platforms.

If there is an existing TPM 1.2 installed in the server, you cannot upgrade to TPM 2.0.

If there is no existing TPM in the server, you can install TPM 2.0. You must first upgrade to Intel v4 code, regardless of whether the installed CPU is Intel v3 or v4. TPM 2.0 requires Intel v4 code or later.

Caution If your Intel v3 or Intel v4 system is currently supported and protected by TPM version 2.0, a potential security exposure might occur if you downgrade the system software and BIOS to a version earlier than those shown in Table 3 below.

Note If the TPM 2.0 becomes unresponsive, reboot the server.
