Step 3 Open the Cisco IMC Configuration Utility:
a. Press the Power button to boot the server. Watch for the prompt to press F8.
b. During bootup, press F8 when prompted to open the Cisco IMC Configuration Utility. Note the
differences between versions of Cisco IMC firmware:
– In Cisco IMC 2.0(1) and later, there are two windows for this utility that you can switch between
by pressing F1 or F2 (see Figure 2-6 for sample windows). The IPv4 and IPv6 protocols and
dynamic domain name system (DDNS) are supported. You can also define a host name and a
DDNS domain.
– In Cisco IMC earlier than release 2.0(1), there is only one window for this utility. Only the IPv4
protocol is supported. DDNS is not supported.

Step 4
Set NIC mode and NIC redundancy:
a. Set the NIC mode to your choice for which ports to use to access the CIMC for server management
(see Figure 1-3 for identification of the ports):
• Shared LOM EXT (default)—This is shared LOM extended mode. This is the factory-default
setting, along with Active-active NIC redundancy and DHCP-enabled. With this mode, the shared
LOM and Cisco Card interfaces are both enabled.
In this mode, DHCP replies are returned to both the shared LOM ports and the Cisco card ports. If
the system determines that the Cisco card connection is not getting its IP address from a Cisco UCS
Manager system because the server is in standalone mode, further DHCP requests from the Cisco
card are disabled. Use the Cisco Card NIC mode if you want to connect to the CIMC through a Cisco
card in standalone mode.
• Dedicated—The dedicated management port is used to access the CIMC. You must select a NIC
redundancy and IP setting.
• Shared LOM—The 1-Gb Ethernet ports are used to access the CIMC. You must select a NIC
redundancy and IP setting.
• Cisco Card—The ports on an installed Cisco UCS virtual interface card (VIC) are used to access the
CIMC. You must select a NIC redundancy and IP setting.
Note The Cisco Card NIC mode is currently supported only with a Cisco UCS VIC that is installed in
PCIe slot 2. See also Special Considerations for Cisco UCS Virtual Interface Cards, page 3-43.
