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


Use PuTTY to log in to the server over a serial port in either of the following scenarios:

  • The server is configured for the first time at a new site.
  • A remote connection to the server cannot be established.

The server in this section can be a management module, compute node, or switching plane.


  • A PC is connected to the server by using a serial cable.
  • PuTTY 0.60 or later has been installed.
  • You have obtained the user name and password for logging in to the server to be connected.
  • You have installed PuTTY.exe. PuTTY 0.60 or later is required for login over a serial port.


  1. Double-click PuTTY.exe.

    The PuTTY Configuration window is displayed.

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

    The following are examples:

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

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

  4. In the navigation tree, choose Session.
  5. Select Connection type in Serial, as shown in Figure 3-40.
