Installing External SCSI Devices

Assigning a SCSI Address to the External Device
You must shut down your system to install an external device, but before doing so you
must assign an address to the device.
Note: Set addressesmanuallyonly on external SCSI devices.Bus1 (the external bus) has
addresses such as 1-1, 1-2, 1-3. The second number is the number the user sets.
• If you currently do not have any external devices attached to your system, you can
assign any number between 1 and 15 (for wide SCSI devices) or 1 and 7 (for narrow
devices) to the new device. Do not use address 0, as this is the system SCSI ID. Skip
to “Setting the SCSI Address on the External Device.”
• If you have at least one external device attached to your system and you are adding
another device, you must check which addresses are assigned to the existing
external devices and then choose a number between 1 and 15 (for wide SCSI
devices) or between 1 and 7 (for narrow SCSI devices) that has not already been
assigned.
Note: Although the OCTANE workstation allows up to 15 addresses for SCSI
devices, the devices themselves may have dials that allow you to set a number only
between 1 and 9.
To check available addresses for external devices, follow these steps:
1. If the OCTANE workstation is powered off, turn on the system power.
■ Open the door on the front of the OCTANE workstation.
■ Press and release the power button to power on the system.
2. Log in to your account. For more information on logging in, refer to “Logging Into
the OCTANE Workstation” on page 24.
3. When the system comes up, from the Toolchest > System > System Manager >
Hardware and Devices, choose “Removable Media Manager.”
You see a listing of your system’s hardware devices and their address numbers.
4. Choose a number between 1 and 15 (for a wideSCSI device) orbetween 1 and 7 (for
a narrowSCSI device) thatis not assignedto yourcurrent devices andthen gotothe
next section, “Setting the SCSI Address on the External Device.”
