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

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

This topic describes how to use PuTTY to remotely log in to a server over a serial port and to configure and maintain the server.

Scenarios

Log in to a server over a serial port by using PuTTY in the following scenarios:

  • The server is configured for the first time at a new site, and you need to perform initial configuration.
  • The server cannot be remotely connected to because the network is faulty, and you need to locate the fault.
    NOTE:

    The server 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

Data

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

Software

PuTTY.exe: third-party 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.

    The following are the examples:

    • Serial line to connect to: COMn
    • Speed (baud): 115200
    • Data bits: 8
    • Stop bits: 1
    • Parity: None
    • Flow control: None
    NOTE:

    n indicates the serial port number, and the value is an integer.

  5. In the navigation tree, choose Session.
  6. Select Connection type in Serial.

  7. Click Open.

    The PuTTY window and login as: are displayed, waiting for you to enter a user name.

    login as:

  8. Enter a user name and password by following instructions.

    After login, the server host name is displayed on the left of the prompt.
