After establishing the cabling discussed earlier, Cisco UCS Fabric Interconnect needs to be initially configured with a management IP address. This will allow the system to manage it remotely through GUI or CLI. Connect to the first Fabric Interconnect console using a serial connection. Configure the first Fabric Interconnect using the following steps:

1. Select the installation method:

        Enter the installation method (console/gui)? Console

2. Select the initial setup:

        Enter the setup mode (restore from backup or initial setup)
        [restore/setup]? Setup

3. Type in y to continue:

        You have chosen to setup a new switch. Continue? (y/n): y

4. Choose a complex password:

        Enter the password for "admin": password

5. Retype the password:

        Confirm the password for "admin": password

6. Choose the creation of a new cluster by selecting yes:

        Do you want to create a new cluster on this switch  
        (select 'no' for standalone setup or if you want this switch
        to be added to an existing cluster)? (yes/no) [n]: yes

7. A or B will be suffixed to the name defined in the next step:

        Enter the switch fabric (A/B): A

8. Enter the name of the Fabric Interconnect:

        Enter the system name: FI

9. Enter the management IP address:

        Mgmt0 IPv4 address: 172.16.1.10

10. Enter the subnet mask:

        Mgmt0 IPv4 netmask: 255.255.255.0

11. Enter the address of the default gateway of the management network:

        IPv4 address of the default gateway: 172.16.1.1

12. Enter the shared IP of the cluster:

        Virtual IPv4 address : 172.16.1.12

13. Type in yes to configure the DNS:

        Configure the DNS Server IPv4 address? (yes/no) [n]: yes

14. Enter the DNS server IP address which is providing name services:

        DNS IPv4 address: 8.8.8.8

15. Type in yes to configure the domain name:

        Configure the default domain name? (yes/no) [n]: yes

16. Enter the domain name of the company:

        Default domain name: yourcompany.com

17. After pressing Enter, the cluster configuration will be confirmed with a summary of configurations. The following configurations will be applied:
    • Switch Fabric = A
    • System Name = FI
    • Management IP Address = 172.16.1.10
    • Management IP Netmask = 255.255.255.0
    • Default Gateway = 172.16.1.1
    • Cluster Enabled = yes
    • Virtual IP Address = 172.16.1.10
    • DNS Server = 8.8.8.8
    • Domain Name = yourcompany.com
18. Type in yes to save the changes:

        Apply and save the configuration (select 'no' if you
        want to re-enter)? (yes/no): yes
