Overview Ultra160 SCSI on the Adaptec SCSI Card 29160 The Adaptec SCSI Card 29160 supports Ultra160 SCSI devices. Ultra160 is a new generation of SCSI technology that expands SCSI performance from 80 MBytes/sec to 160 MBytes/sec. In addition to providing much greater performance, Ultra160 SCSI enables a maximum allowable cable length of 12 meters for optimal connectivity and flexibility.1 The Adaptec SCSI Card 29160 combines this Ultra160 SCSI technology with Adaptec’s SpeedFlex™ technology.
Adaptec SCSI Card 29160 User’s Reference Note: Read the Adaptec SCSI Card 29160 Installation Guide if you need instructions on installing the SCSI Card and connecting SCSI devices to it. Understanding SCSI SCSI (pronounced “scuzzy”) stands for Small Computer Systems Interface. SCSI is an industry standard computer interface for connecting SCSI devices (such as a hard disk drive, CD-ROM drive, or scanner) to a common SCSI bus.
Overview ■ SCSI ID 7 has the highest priority on the SCSI bus. The priority of the remaining IDs, in descending order, is 6 to 0, then 15 to 8. ■ The Adaptec SCSI Card 29160 is preset to SCSI ID 7 and should not be changed. This gives it the highest priority on the SCSI bus. ■ Most internal SCSI hard disk drives come from the factory preset to SCSI ID 0. ■ If you have 8-bit (or Narrow) SCSI devices, they must use SCSI IDs 0, 1, 2, 3, 4, 5, or 6.
Adaptec SCSI Card 29160 User’s Reference 4 ■ Termination on non-Ultra160 and Ultra2 internal SCSI devices usually is controlled by manually setting a jumper or a switch on the device, or by physically removing or installing one or more resistor modules on the device. ■ Termination on most external SCSI devices is controlled by installing or removing a SCSI terminator. However, termination on some external SCSI devices is enabled or disabled by setting a switch on the back of the SCSI device.
Troubleshooting Troubleshooting Most problems can be resolved by following the recommendations in the Troubleshooting Checklist below. If you still experience problems after following the recommendations, continue with the rest of this section. Troubleshooting Checklist Most problems with using the Adaptec SCSI Card 29160 result from errors in preparing and connecting devices on the SCSI bus. If you have problems, check these items first.

Adaptec SCSI Card 29160 User’s Reference Common Error Messages Here is what you should do if the following messages appear at bootup: “Device connected, but not ready” The host received no answer when it requested data from an installed SCSI device. 1 Run SCSISelect® and set the Send Start Unit Command to Yes for the particular SCSI device ID. See Starting SCSISelect on page 18. 2 Ensure that the device is set to spin up when the power is switched on. The spin up option is typically set by a jumper.
Troubleshooting SCSISelect termination option for the SE connector to Automatic or Enable. “Attention! Insufficient termination detected on the SE connectors” The SCSI card BIOS has detected only one terminated device, or no terminated devices, on the SE (single-ended) segment. Verify the termination on both the 68-pin internal SE and 50-pin internal SE connectors. Terminate only the last SCSI device at the end of each cable.
Adaptec SCSI Card 29160 User’s Reference Using the Adaptec SCSI Card 29160 and SCSI Devices This section provides useful information on using the Adaptec SCSI Card 29160 and your SCSI devices. For more information about a specific SCSI device, refer to the documentation for that device.
Using the Adaptec SCSI Card 29160 and SCSI Devices Using Ultra160 Hard Disk Drives ■ We recommend that you connect your LVD (Ultra160 and Ultra2) SCSI devices to the two 68-pin connectors on the LVD-SE SCSI segment and that you connect your non-LVD SCSI devices (if any) to the two SE (single-ended) connectors on the SE SCSI segment. This allows the LVD SCSI devices to run at their maximum performance levels of 160 MBytes/sec or 80 MBytes/sec.
Adaptec SCSI Card 29160 User’s Reference Combining SCSI and Non-SCSI Devices You can install the Adaptec SCSI Card 29160 in a computer that already has a non-SCSI controller, such as an EIDE controller. However, you cannot cross-connect the disk drives and other devices: SCSI devices must be connected to the Adaptec SCSI Card 29160, EIDE devices must be connected to the EIDE controller, and so on.
Using the Adaptec SCSI Card 29160 and SCSI Devices Installing Multiple SCSI Cards ■ You can install multiple SCSI cards in your computer; you are limited only by the available system resources (for example, IRQ settings, I/O port addresses, BIOS addresses, and so forth). ■ Each SCSI card you install forms a separate SCSI bus with a different set of SCSI devices.
Adaptec SCSI Card 29160 User’s Reference Configuring the Adaptec SCSI Card 29160 with SCSISelect SCSISelect, included with the Adaptec SCSI Card 29160, enables you to change SCSI settings without opening the computer or handling the card. SCSISelect also enables you to low-level format or verify the disk media of your SCSI hard disk drives. The following table lists the available and default settings for each SCSISelect option.

Adaptec SCSI Card 29160 User’s Reference Starting SCSISelect Follow these steps to start SCSISelect: 1 Turn on or restart your system. During the startup process, pay careful attention to the messages that appear on your screen.
Configuring the Adaptec SCSI Card 29160 with SCSISelect SCSI Bus Interface Definitions ■ Host Adapter SCSI ID—(Default: 7) Sets the SCSI ID for the SCSI card. The Adaptec SCSI Card 29160 is set at 7, which gives it the highest priority on the SCSI bus. We recommend that you do not change this setting. ■ SCSI Parity Checking—(Default: Enabled) When set to Enabled, verifies the accuracy of data transfer on the SCSI bus.
Adaptec SCSI Card 29160 User’s Reference ■ Initiate Wide Negotiation—(Default: Yes) When set to Yes, the SCSI card attempts 16-bit data transfer (wide negotiation). When set to No, the SCSI card uses 8-bit data transfer unless the SCSI device requests wide negotiation. Note: Set Initiate Wide Negotiation to No if you are using an 8-bit SCSI device that hangs or exhibits other performance problems with 16-bit data transfer rate enabled.
Configuring the Adaptec SCSI Card 29160 with SCSISelect Advanced Configuration Options Note: Do not change the Advanced Configuration Options unless absolutely necessary. ■ Reset SCSI Bus at IC Initialization—(Default: Enabled) When set to Enabled, the SCSI card generates a SCSI bus reset during its power-on initialization and after a hard reset.
Adaptec SCSI Card 29160 User’s Reference ■ Set to Disabled: Not scan if the devices on the SCSI bus (for example, CD-ROM drives) are controlled by software drivers and do not need the BIOS, and you do not want the BIOS to scan the SCSI bus. ■ Set to Disabled: Scan Bus if you do not need the BIOS, but you want it to scan the SCSI devices on the bus and you need to spin up the devices. The following four options have no effect when the SCSI Card BIOS is disabled.
Configuring the Adaptec SCSI Card 29160 with SCSISelect ■ BIOS Support for Int 13 Extensions—(Default: Enabled) When set to Enabled, the SCSI card BIOS supports Int 13h extensions as required by Plug-and-Play. The setting can be either enabled or disabled if your system is not Plug-and-Play. Using SCSI Disk Utilities To access the SCSI disk utilities, follow these steps: 1 Select the SCSI Disk Utilities option from the menu that appears after starting SCSISelect.
Adaptec SCSI Card 29160 User’s Reference Connecting SCSI Devices Here are some examples of how you can connect internal and external SCSI devices to the Adaptec SCSI Card 29160. To achieve maximum performance, attach the first device to the end connector (furthest from the SCSI card); attach other devices to the connectors that are closer to the SCSI card. The first example shows SCSI devices connected to all four internal and external connectors.
Connecting SCSI Devices The following example shows two Ultra160/Ultra2 SCSI devices connected to the external connector. As in the previous diagrams, the last device on the SCSI bus must use an LVD/SE terminator plug in order to operate at its maximum speed. Terminated device T Maximum Cable Lengths The total length of cabling (internal and external) on the SCSI bus cannot exceed the maximum lengths listed in the following table.
