The hot-swap-drive backplane controls the SCSI IDs for the internal hot-swap drive
bays. However, when you attach an external SCSI device to an optional SCSI
adapter, you must set a unique ID for the device. See the information that comes
with the device for instructions to set its SCSI ID.
SCSI connectors
The following illustration shows the 68-pin, female D-shell SCSI connectors. These
connectors conform to the SCSI standard.

Serial ports
Your server has one standard serial port that the operating system can use and one
optional serial port.
Some application programs require specific ports, and some modems function
properly only at certain communication-port addresses. You might need to use the
Configuration/Setup Utility program to change communication-port address
assignments to prevent or resolve address conflicts.
Viewing or changing the serial-port assignments
To view or change the serial-port assignments:
1. Restart the server and watch the monitor screen.
2. When the message Press F1 for Configuration/Setup appears, press F1.
3. From the main menu, select Devices and I/O Ports ; then, press Enter.
Note: The Devices and I/O Ports choice appears only on the full configuration
menu. If you set two levels of passwords, you must type the
administrator password to access the full configuration menu.
