Step 6 Replace all the 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, page 2).
• 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.
Minimum Software and Firmware Requirements
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, page 2.

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, page 2).
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.
Use the instructions in the Cisco Host Upgrade Utility User Guide 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).

Minimum Software and Firmware Requirements
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 8 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

TPM 2.0 Considerations
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.
