7.6 Connect to ILOM via a Serial Connection

You can connect to ILOM via a serial connection if you are unable to access ILOM via the network due to any of the following problems:

• Misconfiguration of the network

• Misconfiguration of ILOM IP addresses

• Misconfiguration of Cisco Ethernet switch ports

• Sideband configuration issues

Note:

You can reconfigure network access after connecting to ILOM via a serial connection. For more information, see Reconfigure the Network Access.

7.6.1 Connect to the ILOM of a Compute Node

To connect to ILOM of a compute node in the Exalogic machine using a serial connection, complete the following steps:

1. Attach a serial cable from a terminal or a PC running terminal emulation software to the SER MGT port of an Exalogic compute node. The cable should be of length 15 feet or less.
2. Verify that your terminal or laptop is operational.
3. Configure the terminal device or the terminal emulation software to use the following settings:

   • 8N1: eight data bits, no parity, one stop bit

   • 9600 baud (default, but can be set to any standard rate up to 115200)

   • Disable software flow control (XON/XOFF)

   • Disable hardware control

4. Verify that power is supplied to either PSU.

   If there is power applied to either PSU, then ILOM will be functional regardless of the power state of compute nodes.

5. Press Enter on the terminal device. A connection between the terminal device and the ILOM is established.

   The ILOM login prompt is displayed.

6. Log in to the CLI using the default user name root.

   The ILOM default command prompt is displayed.

7.6.2 Connect to the ILOM of a Sun Network QDR InfiniBand Gateway Switch

To connect to ILOM of a Sun Network QDR InfiniBand Gateway Switch in the Exalogic machine using a serial connection, complete the following steps:

1. Attach a USB-to-Serial connector to the USB port of the gateway switch.
2. Verify that your terminal or laptop is operational.
3. Configure the terminal device or the terminal emulation software to use the following settings:

   • 8N1: eight data bits, no parity, one stop bit

   • 115200 baud

   • Disable software flow control (XON/XOFF)

   • Disable hardware control

4. Press the Return or Enter key on the serial device several times to synchronize the connection.

   You may see text similar to the following:

   where nm2name is the host name of the management controller. The name might be the word hostname.

   Even if you do not see the text, go to Step 5.

5. Log in as the root user. The # prompt is displayed.

   Note:

   If you do not see this output or prompt, there is a problem with the serial configuration, the USB-to-Serial connector, or the CLI.
