Logging In to a Device Over a Serial Port by Using PuTTY

Logging In to a Device Over a Serial Port by Using PuTTY

Scenarios

Log in to a compute node, switch module, or management module in an E9000 chassis over a serial port by using PuTTY when:

  • You want to perform initial configuration of the device.
  • The device is inaccessible over a network port.
    NOTE:

    The device that is logged in to is a management module, compute node, or switch module in an E9000 chassis.

    When logging in to a management module, you must connect the serial port to the COM serial port of the MM910.

    When logging in to a compute node, you can connect the serial port to the SYS serial port or BMC chip of the compute node.
    • The E9000 compute nodes do not provide serial ports. To log in to a compute node over a serial port, connect a multi-port cable to a universal connector port (UCP) and log in through the serial port of the multi-port cable. If the compute node does not provide a UCP, you can log in to the compute node only through a network port. For details, see Logging In to a Compute Node or a Switch Module over MM910 SOL.
    • On the MM910 CLI, run the bmccomstate and switchcom commands to query and switch the objects connected to the serial ports. For details, see the MM910 Management Module V100R001 Command Reference.

    When logging in to a switch module, you can connect the serial port to the Ethernet switching plane, FC switching plane, or BMC chip.

    • If the switch module panel has the BMC serial port and SYS serial port, the BMC serial port is connected to the BMC chip, and the SYS serial port can be connected to the Ethernet switching plane or FC switching plane.
    • If the switch module panel has only the COM serial port, the COM serial port can be connected to the Ethernet switching plane, FC switching plane, or BMC chip.
    • If the switch module panel has only the BMC serial port, the BMC serial port is connected to the BMC chip.
    • On the MM910 CLI, run the bmccomstate and switchcom commands to query and switch the objects connected to the serial ports. For details, see the MM910 Management Module V100R001 Command Reference.

Prerequisites

Conditions

None.

Data

User name and password for logging in to the target device.

Software

PuTTY 0.60 or later.

Procedure

  1. Connect the local PC and the target device through a serial cable.

    The connection varies depending on the target device:

    • Compute node: Connect the local PC to the serial port of the multi-port cable of the target compute node.
    • Switch module: Connect the local PC to the serial port of the target switch module.
    • Management module: Connect the local PC to the serial (COM) port of the target MM910.

  2. Double-click PuTTY.exe.

    The PuTTY Configuration window is displayed.

  3. In the navigation tree on the left, choose Connection > Serial.
  4. Set the login parameters.

    Example:

    • Serial Line to connect to: COMn
    NOTE:

    n indicates the serial port number.

    • Speed (baud): 115200
    • Data bits: 8
    • Stop bits: 1
    • Parity: None
    • Flow control: None

  5. Choose Session from the navigation tree, and select Serial for Connection type, as shown in Figure 6-3.

    Figure 6-3 PuTTY Configuration

  6. Click Open.

    The following information is displayed:

    login as:

  7. Enter the user name and password.

    If the log in is successful, the host name is displayed on the left of the prompt.
