+.. _install_login_fuel_master_node:
+
+Log in to the Fuel Master node
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When Fuel completes the installation of the Fuel Master node, the Fuel Master
+node boots automatically and the *Welcome to the Fuel server* message displays.
+The message contains Fuel web UI and Fuel command-line interface default login
+credentials.
+
+.. warning::
+
+   Remove the installation media before booting the system.
+   You may damage or delete the entire environment
+   by booting the installation media once again accidentally.
+   This is especially important if you set the boot order
+   so that the USB or DVD drive boots before the hard disk.
+
+Log in to the Fuel Master node for further configuration using one of
+the following options:
+
+* Log in to the Fuel web UI.
+* Log in to the Fuel CLI.
+
+You can perform most of the operations in both Fuel web UI and Fuel CLI.
+However, for your convenience, we recommend that you use the Fuel web UI for
+initial configuration.
+
+**To log in to the Fuel web UI:**
+
+#. In a web browser, type the IP address and port number that you have
+   assigned for the Fuel web UI in `install_set_up_fuel`.
+
+   Fuel prompts you for the login credentials.
+
+#. In a web browser, enter the Fuel UI login and password that you have
+   set for the Fuel web UI in `install_set_up_fuel`
+
+   If you use the default network settings, use the following values:
+
+   * IP address: ``https://10.20.0.2:8443/``
+   * Fuel UI login: ``admin``
+   * Fuel UI password: ``admin``
+
+   .. note::
+
+      The IP address must be reachable from the machine on which you open
+      the Fuel web UI URL.
+
+   .. warning::
+
+      For security reasons, change the default credentials for
+      the administrator account.
+
+   The Fuel web UI initial screen displays.
+
+#. Proceed to `install_boot_the_fuel_slave_nodes`.
+
+**To log in to the Fuel CLI:**
+
+#. In the Fuel Master node console, type the root login and password that you
+   have assigned in `install_set_up_fuel`.
+
+   If you use the default settings, type the following login credentials:
+
+   * Login: ``root``
+   * Password: ``r00tme``
+
+   You can change the password using the :command:`passwd` command after
+   you log in.
+
+   .. warning::
+
+      For security reasons, change the default credentials for the root
+      account.
+
+#. Alternatively, connect to the Fuel Master node :ref:`using SSH <shell-ops>`.
+
+#. Proceed to `install_boot_the_fuel_slave_nodes`.

+.. _install_login_fuel_master_node_multiple_nics:
+
+Log in to the Fuel Master node with multiple NICs
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If the server on which the Fuel Master node is installed has more than one
+network interface card (NIC), you can access the Fuel web UI with a particular
+NIC.
+
+**To access the Fuel web UI with a particular NIC:**
+
+#. Connect the NIC to the appropriate switch.
+#. On the Fuel Master node, set an IP address for the NIC.
+#. Use the IP address that you assigned to log in to the Fuel web UI.
+   For example: ``https://IP_YOU_ASSIGN:8443/``
+
+.. note::
+
+   The tasks above do not change the default administrator network settings.
+   You can access the Fuel web UI using the URL displayed on the Fuel boot
+   screen.
