If you plan to attach more than one external serial device, you must install the optional second serial port. Installing the external SCSI connector Complete the following steps to install the optional external SCSI connector needed to attach an external SCSI device: 1. Review the information in "Installation guidelines" on page 45, "Handling static-sensitive devices" on page 46, and "Safety information" on page 169. 2. Turn off the server and disconnect all power cords and external cables ("Turning off the server" on page 9); then, remove the server cover (see "Removing the server left-side cover and bezel (tower model)" on page 55 or "Removing the server top cover and bezel (rack configuration)" on page 57). Attention: To ensure proper system cooling, do not remove the server cover for more than 30 minutes during this procedure. 3. Remove the external SCSI knockout on the rear of the server (see "Cabling the server" on page 106 for external SCSI knockout location). 4. Follow the instructions that come with the option to prepare it for installation and to connect it to the server. 5. Route one end of the optional external SCSI cable to the external SCSI B connector (J51) on the system board (see "System-board internal cable connectors" on page 49 for the location of the SCSI connector); then, secure the external SCSI connector at the other end of the cable into the external SCSI knockout hole on the rear of the server. 6. Reinstall the server cover (see "Installing the server bezel and left-side cover (tower model)" on page 100 or "Installing the server bezel and top cover (rack configuration)" on page 103). 7. Reconnect all the devices, power cords, and cables that you disconnected; then, turn on the server and all attached devices. Installing the second serial connector Complete the following steps to install the optional second serial connector needed to attach more than one external serial device: 1. Review the information in "Installation guidelines" on page 45, "Handling static-sensitive devices" on page 46, and "Safety information" on page 169. 2. Turn off the server and disconnect all power cords and external cables ("Turning off the server" on page 9); then, remove the server cover (see "Removing the server left-side cover and bezel (tower model)" on page 55 or "Removing the server top cover and bezel (rack configuration)" on page 57). Attention: To ensure proper system cooling, do not remove the server cover for more than 30 minutes during this procedure. 3. Remove the optional serial connector knockout on the rear of the server (see "Cabling the server" on page 106 for external SCSI knockout location). 4. Route one end of the optional serial connector cable to the optional serial connector (J48) on the system board (see "System-board internal cable connectors" on page 49 for the location of the optional serial connector); then, secure the serial connector at the other end of the cable into the serial knockout hole on the rear of the server. 5. Reinstall the server cover (see "Installing the server bezel and left-side cover (tower model)" on page 100 or "Installing the server bezel and top cover (rack configuration)" on page 103).
