Cisco UCS C-Series Servers Upgrade Guide for Intel Xeon v4 Series CPUs

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 v4 Series.

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

Note If you have a C460 M4 server that is using DDR3 memory, this procedure instructs you to also replace the memory risers and DIMMs with DDR4 versions.

Step 1 Upgrade the Cisco UCS Manager software to the minimum version for your server (or later). See Table 2 .

Use the procedures in the appropriate Cisco UCS Manager upgrade guide (depending on your current software version): Cisco UCS Manager Upgrade Guides.

Step 2 Use Cisco UCS Manager to upgrade and activate the server Cisco IMC to the minimum version for your server (or later). See Table 2 .

Use the procedures in the GUI or CLI Cisco UCS Manager Firmware Management Guide 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.

Step 3 Use Cisco UCS Manager to upgrade and activate the server BIOS to the minimum version for your server (or later). See Table 2 .

Use the procedures in the Cisco UCS Manager GUI or CLI Cisco UCS Manager Firmware Management Guide for your release.

Step 4 Decommission and then power off the server.

Step 5 Replace the CPUs with the Intel Xeon v4 Series CPUs.

Use the CPU replacement procedures in the Installation and Service guide for your server: Cisco UCS C-Series Installation and Upgrade Guides.

Note The following step is for only C460 M4 servers that have DDR3 memory. Skip the following step if your server is already using DDR4 memory.

Step 6 Replace all the C460 M4 DDR3 memory risers and DIMMs in the server with new DDR4 memory risers and DIMMs.

Use the DIMM and memory riser replacement procedures in the Installation and Service guide for your server: Cisco UCS C-Series Installation and Upgrade Guides.

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 v4 Series.

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

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).

Use the procedures in the Cisco Host Upgrade Utility User Guide 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 v4 Series CPUs.

Use the CPU replacement procedures in the Installation and Service guide for your server: Cisco UCS C-Series Installation and Upgrade Guides.

Note The following step is for only C460 M4 servers that have DDR3 memory. Skip the following step if your server is already using DDR4 memory.

Step 4 Replace all the C460 M4 DDR3 memory risers and DIMMs in the server with new DDR4 memory risers and DIMMs.

Use the DIMM and memory riser replacement procedures in the Installation and Service guide for your server: Cisco UCS C-Series Installation and Upgrade Guides.

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 v4 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 v4 Series CPUs (after the CPUs are transferred from the defective server).
• C460 M4 servers only: 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 Transfer the Intel Xeon v4 Series CPUs from the defective server to the replacement server.

Note The following step is for only C460 M4 servers. Skip the following step if your server is not a C460 M4.

Step 2 For C460 M4 servers, transfer the DDR4 DIMMs and DDR4 memory risers to the replacement server.

Step 3 Power on the 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 4 Download the HUU ISO file for your minimum release (or later) from Cisco.com and save it on a laptop or other computer.

Use the instructions in the Cisco Host Upgrade Utility User Guide for your release.

Step 5 Mount the ISO image.

Step 6 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 7 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 8 Use the Cisco IMC GUI in a browser to log in as administrator on the IP address of the target server.

Step 9 Use the Cisco IMC GUI to install and activate the Cisco IMC minimum version for your server (or later).

Use the procedures in the Cisco UCS C-Series Integrated Management Controller GUI Configuration Guide for your release.

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

Use the procedures in the Cisco UCS C-Series Integrated Management Controller GUI Configuration Guide for your release.

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.

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.

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:

There is an update available for Chassis Firmware, would you like to continue?

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

Step 4 Click OK 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:

• 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:

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

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