User manual SOEHNLE VENEZIA

[. . . ] Most SCSI devices currently in use, however, do not support SCAM. The SCSI IDs on these devices must be set manually. To change the SCSI IDs on these devices, refer to the device's documentation. Note: If you plan to boot your computer from a SCSI device attached to the host adapter, set the Boot Target ID setting in the SCSISelect utility to correspond to the SCSI ID of the device you are booting from (see Configuring the Host Adapter on page 7). SCSI Terminators To ensure reliable communication, the SCSI bus must be properly terminated. Termination is controlled by a set of electrical resistors, called terminators. [. . . ] We recommend that you leave the AHA-2940Ultra Wide set to its default setting of Automatic. If you want to manually set the AHA-2940Ultra Wide termination setting, see Configuring the Host Adapter on page 7. The following table lists the termination settings for manual configuration. AHA-2940Ultra Wide Termination Devices Connected to AHA-2940Ultra Wide 68-pin internal connector only 68-pin external connector only 68-pin internal and 68-pin external connectors 50-pin internal connector only 50-pin and 68-pin internal connectors 50-pin internal and 68-pin external connectors Low ON ON OFF ON OFF OFF High ON ON OFF ON ON ON Terminating SCSI Devices Read the device's documentation to determine how to enable or disable termination on your particular SCSI device(s). On most internal SCSI devices the termination setting is controlled by a jumper or a switch. On other internal SCSI devices you must physically remove or install resistor module(s). On most external SCSI devices, a terminating plug (a resistor pack embedded in a small plug) is installed or removed to control termination. 4 4 Installing SCSI Devices You can connect up to a total of seven internal and external 8-bit SCSI devices to the AHA-2940Ultra, and up to 15 devices (seven 8-bit internal and eight Wide (16-bit) internal or external SCSI devices, or 15 Wide internal and external SCSI devices) to the AHA-2940Ultra Wide. Note: You may only use two of the three connectors at any one time on the AHA-2940Ultra Wide host adapter. Choosing SCSI Cables The cables required to connect SCSI devices are determined by the type of devices you are installing, as described in the following table. SCSI Device Type 8-bit Internal SCSI 8-bit External SCSI 16-bit Internal Wide SCSI 16-bit External Wide SCSI AHA-2940Ultra 50-pin internal SCSI cable 50-pin high-density external SCSI cable -- -- AHA-2940Ultra Wide 50-pin internal SCSI cable -- 68-pin internal SCSI cable 68-pin external SCSI cable If you purchased your AHA-2940Ultra/2940Ultra Wide in an Adaptec kit, the kit includes an internal SCSI cable that allows you to connect up to two internal SCSI devices (the AHA-2940Ultra kit includes a 50-pin internal SCSI cable, and the AHA-2940Ultra Wide kit includes both a 50-pin and a 68-pin internal SCSI cable). If you are connecting more than two internal SCSI devices, you must obtain an internal SCSI cable with enough connectors to accommodate all of your devices. Adaptec sells high-quality internal and external SCSI cables. If your reseller does not stock these cables, you can order them directly from Adaptec. When Fast SCSI devices are connected to the host adapter, the total length of all cables (internal and 5 external) must not exceed 3 meters (9. 8 ft. ) to ensure reliable operation. To restore the original SCSISelect default values, press F6. To toggle the display between color and monochrome modes, press F5 (this feature may not work on some kinds of monitors). Exiting SCSISelect To exit SCSISelect, press Esc until a message prompts you to exit (if you changed any AHA-2940Ultra/ 2940Ultra Wide settings, you are prompted to save the changes before you exit). At the prompt, select Yes to exit, then press any key to reboot the computer. Any changes you made in SCSISelect take effect after the computer boots. Using the SCSI Disk Utilities To access the SCSI disk utilities, select the SCSI Disk Utilities option from the menu that appears after starting SCSISelect. Once the option is selected, SCSISelect 9 immediately scans the SCSI bus and displays a list of all SCSI IDs and the devices assigned to each ID. When you select a specific ID and device, a small menu appears, displaying the options Format Disk and Verify Disk Media. s Format Disk--This utility allows you to perform a low-level format on a hard disk drive. Most SCSI disk devices are preformatted at the factory and do not need to be formatted again. The Adaptec Format Disk utility is compatible with the vast majority of SCSI disk drives. Verify Disk Media--This utility allows you to scan the media of a hard disk drive for defects. If the utility finds bad blocks on the media, it prompts you to reassign them; if you select yes, those blocks are no longer used. [. . . ] However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause interference to radio or television equipment reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: · · · Reorient or relocate the receiving antenna Move the equipment away from the receiver Plug the equipment into an outlet on a circuit different from that to which the receiver is powered · If necessary, the user should consult the dealer or an experienced radio/ television technician for additional suggestions CAUTION: Only equipment certified to comply with Class B (computer input/output devices, terminals, printers, etc. ) should be attached to this equipment, and must have shielded interface cables. Finally, any changes or modifications to the equipment by the user not expressly approved by the grantee or manufacturer could void the user's authority to operate such equipment. Each host adapter is equipped with an FCC compliance label which shows only the FCC Identification number. [. . . ]
