Install the serial port module

Follow the instructions in this section to install the serial port module.

About this task

  • Read Installation Guidelines and Safety inspection checklist to ensure that you work safely.

  • Power off the server and peripheral devices and disconnect the power cords and all external cables. See Power off the server.

  • Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-sensitive components in their static-protective packages until installation, and handling these devices with an electrostatic-discharge wrist strap or other grounding system.

  • If the server is installed in a rack, slide the server out on its rack slide rails to gain access to the top covers, or remove the server from the rack. See Remove the server from rails.

Firmware and driver download: You might need to update the firmware or driver after replacing a component.

  6. To enable the serial port module on Linux or Microsoft Windows, do one of the followings according to the installed operating system:
    If the Serial over LAN (SOL) or Emergency Management Services (EMS) feature is enabled, the serial port will be hidden on Linux and Microsoft Windows. Therefore, it is required to disable SOL and EMS to use the serial port on operating systems for serial devices.
    • For Linux:

      Open the ipmitool and enter the following command to disable the Serial over LAN (SOL) feature:

      -I lanplus -H IP -U USERID -P PASSW0RD sol deactivate
    • For Microsoft Windows:

      1. Open the ipmitool and enter the following command to disable the SOL feature:

        -I lanplus -H IP -U USERID -P PASSW0RD sol deactivate
      2. Open Windows PowerShell and enter the following command to disable the Emergency Management Services (EMS) feature:

        Bcdedit /ems off
      3. Restart the server to ensure that the EMS setting takes effect.
