CHAPTER 3: CABLING AND TERMINATION
ATTO ExpressPCI Ultra2 SCSI host adapters are designed to operate with either low voltage differential or single-ended devices. When connected to single-ended devices, ATTO ExpressPCI Ultra2 negotiates to Ultra/WIDE transfer rates of 40 Mbytes/sec. per channel. When connected to Ultra2/WIDE devices, ATTO ExpressPCI Ultra2 negotiates to Ultra2/WIDE transfer rates of 80 Mbytes/sec. per channel.
To determine your ATTO ExpressPCI Ultra2 SCSI host adapter model, check the label located on the serial number end of the product box. The model you have will be printed on the barcode label. After determining whether you are using a single channel or dual channel model, the next step in the cabling and termination process is to identify whether SCSI devices will be installed internally or externally. This determines which cables are used and how to connect your SCSI device terminators.
Cabling for the ATTO ExpressPCI UL2S & UL2D SCSI Adapters
The ATTO ExpressPCI UL2S has one industry standard 68-pin “P” (16-bit) VHDCI (Very High Density Cabled Interconnect) cable connector for external device connections and one 68-pin “P” (16-bit) cable connector for internal device connections. The ATTO ExpressPCI UL2D has two industry standard 68-pin “P” (16­bit) VHDCI cable connectors.
By definition, the Ultra2 SCSI specification limits the total bus cable length to 12 meters or approximately 38 feet (this is a combined figure of both internal and external cable lengths). Try to keep cable lengths as short as possible to ensure higher signal quality and performance.
If using a combination of Wide 16-bit devices and Narrow 8-bit devices on the same connector, Wide devices must be connected first (closest to the connector), followed by the Narrow devices. Please refer to the documentation for your SCSI devices to determine if device is Wide or Narrow, and if it is an UltraSCSI or Ultra2 SCSI device.
Cable Types
With all varieties of SCSI, be sure to use high quality SCSI-3 rated, well-insulated SCSI cables to ensure error free communications. The following illustrations depict the types of internal and external cable connectors you may come across.

Termination
The SCSI bus is a chain of SCSI devices. The devices at both ends of any SCSI chain must be terminated for the SCSI bus to function correctly. A SCSI device chain can be configured in three different ways: internal, external and an internal/external SCSI device chain..
Remember an ATTO ExpressPCI Ultra2 SCSI adapter is also a SCSI device and may require termination depending upon the configuration. Be sure to use the correct terminator. Single-ended, low voltage differential and differential SCSI buses use different types of terminators that should not be mixed.
Terminating the Single-Ended ATTO ExpressPCI UL2S and UL2D
Your ATTO ExpressPCI Ultra2 SCSI host adapter incorporates advanced termination circuitry that allows it to automatically configure its own termination.

CHAPTER 4: HARDWARE INSTALLATION
This chapter walks through the process of installing an ATTO ExpressPCI SCSI host adapter and attaching your SCSI devices to it. Please note to get the best performance from your ATTO ExpressPCI host adapters, use Ultra2/WIDE SCSI devices with the ATTO ExpressPCI Ultra2 host adapters.
Before Installing your ATTO ExpressPCI SCSI Adapter
1. Plan your SCSI device connections.
If connecting both internal and external devices to the ATTO ExpressPCI SCSI adapter, be sure to obtain the appropriate cabling to connect devices. Cables,
adapters and terminators are available through ATTO.
2. Set SCSI device termination.
Devices at both ends of the SCSI chain must be terminated. Refer to Chapter 3, Cabling & Termination and your device documentation to determine SCSI device termination. Devices in the middle of the chain, including the ATTO ExpressPCI SCSI adapter, must have termination removed or disabled.
When using both internal and external devices attached to the ATTO ExpressPCI Ultra2 SCSI host adapter, it will select proper termination for itself.
3. Set SCSI IDs.
Each device on the SCSI bus requires a unique SCSI ID. If installing a single device, make sure you do not assign it the same SCSI ID as your ATTO ExpressPCI SCSI adapter. The default setting for your ATTO ExpressPCI SCSI adapter is ID 7. It is recommended this setting not be changed. In the event you need to change this setting, refer to the Reconfiguring the ATTO ExpressPCI SCSI Bus section of the ExpressPro-Tools user’s manual.
Please refer to your SCSI device documentation to determine the current SCSI ID and how to change it. Wide (16-bit) SCSI devices can be assigned IDs 0-6 and 8 -15, while Narrow (8-bit) SCSI devices can only be assigned IDs ranging from 0-6.
ATTO ExpressPCI Ultra2 User’s Manual Page 9
Hardware Installation
The ATTO ExpressPCI SCSI adapter installs easily into your system. Review system documentation to select an appropriate slot to install your SCSI adapter.
The combined power consumption of your expansion cards must not exceed the limits specified for your system. If you have more than one expansion card installed, check the information that came with your cards to make sure that their power consumption is within the limits specified in your system documentation.
Please follow these easy procedures to install the ATTO ExpressPCI SCSI adapter:
F Note: Before removing the ATTO ExpressPCI SCSI adapter from its
box, follow the installation procedure listed below to prevent damaging your ATTO ExpressPCI SCSI adapter or your system.
1. Backup any data on the disk(s) that will be attached to the ATTO ExpressPCI
SCSI adapter. This should always be done as a precaution before adding new hardware to your system.

CHAPTER 5: TROUBLESHOOTING
Try the following suggestions to troubleshoot the ATTO ExpressPCI SCSI adapter.
Check all cable connections to each device. Verify that all cables are in proper
working condition.
Compare the termination of your system to the description in the Termination
section of Chapter 3.
Verify that all of the devices attached to the ATTO ExpressPCI SCSI adapter have
unique SCSI IDs. Remember the ATTO ExpressPCI SCSI adapter has a SCSI ID of 7 by default.
If the same device shows up at several different SCSI IDs, either its SCSI ID is set
the same as the ATTO ExpressPCI’s SCSI ID, or the cable is defective.
Check to see if external SCSI devices are all plugged into an AC outlet and turned
on prior to powering-up your PC.
If a device does not appear: Verify that cables and termination are set properly. If
this doesn’t rectify the problem, try lengthening the SCSI Reset Delay. (Refer to ExpressPro-Tools user’s manual).
PC Users should be sure to check computer’s CMOS setup and verify the PCI slots
are configured correctly. Procedures vary greatly, refer to the manual supplied with your system or call your computer supplier for configuration assistance.

APPENDIX C: SCSI DEVICE & CABLING LIMITATIONS
Due to the electrical noise incurred with high-speed data transfer rates, SCSI has cabling and device limitations. Table C-1 explains the maximum number of devices you may use relative to your cable distance. For example, take the single-ended distance in an UltraSCSI environment (Cells 3 & 4 in the single-ended bus length column). Look at the corresponding cells in the maximum devices column to determine the maximum number of devices you may connect at the specific distance. In an UltraSCSI environment, using a single-ended bus length of 3 meters, you can only connect 4 devices. Using a single-ended bus length of 1.5 meters, you can connect up to 8 devices.

SCSI
Table C-1: UltraSCSI Cabling and Device Limitations
Table C-1 lists the maximum number of devices you may connect at specific cable distances using differential and single-ended SCSI in various SCSI environments. In an UltraSCSI workgroup environment with a 7-drive tower, you are limited to 1.5 meters between the host and tower (this distance includes the cabling in the tower). For example, if the 7-drive tower requires 1 meter of cabling to connect all of its drives, the distance from the tower to the host would be .5 meters. Adding an ATTO SCSI Sidekick to this configuration would increase the distance between the host and tower to 2 meters.
Ultra2 SCSI is less sensitive to SCSI bus noise and offers you the ability to connect a full load of devices up to 12 meters. Use table C-1 to assist you when attempting to configure your workgroup. If you have any questions or issues occur with your configuration, please call an ATTO technical support representative.
