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.
