Install a serial port module

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

About this task

Attention

  • 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.

Procedure

  1. Touch the static-protective package that contains the new part to any unpainted surface on the outside of the server. Then, take the new part out of the package and place it on a static-protective surface.
  2. Use a 5 mm wrench to install the serial port cable into the bracket.

    1. Lower the riser assembly into the chassis.
    2. Tighten the screw to secure the riser cage.
  5. Connect the cable of the serial port module to the system board assembly. See Internal cable routing.

After you finish

  1. Complete the parts replacement. See Complete the parts replacement.

  2. From the UEFI Setup page, click System Settings > Devices and I/O Ports > Console Redirection Settings. Change both Console Redirection and SP Redirection setting to Enabled.

  3. To enable the serial port module on Linux or Microsoft Windows, do one of the followings according to the installed operating system:
    Note
    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.
