Introduction Congratulations on your purchase of Adaptec’s SlimSCSI 1480. The SlimSCSI 1480 delivers full 32-bit PCI performance at speeds up to 20 MBytes/sec., allowing your high-performance SCSI devices to operate at their maximum speed. Enjoy the same versatility and performance as a desktop PC, plus the convenience of instant plug-in connections and hot swapping.
SlimSCSI 1480 User’s Guide Note: The CardBus specification differs from the standard PC Card (PCMCIA) specification. As a result, CardBus adapters like the SlimSCSI 1480 will not operate in, and cannot be inserted in, a standard PC Card slot. Installing the SlimSCSI 1480 Follow these steps to install the SlimSCSI 1480 and connect your SCSI devices to it: 1 Remove the SlimSCSI 1480 from its packaging.
Installing the SlimSCSI 1480 4 Plug the other end of the cable into the first (or only) SCSI device, as shown below. Make sure the SCSI device is not powered. SCSI Connector SCSI Device Terminator 5 (Optional) Connect up to two additional UltraSCSI devices by daisy-chaining them to the first device, as shown below: SCSI Devices Terminator 6 Be sure that each SCSI device has a unique SCSI ID ranging from 0 to 6. If any two devices have the same ID, change the SCSI ID of one device.
SlimSCSI 1480 User’s Guide The diagram below shows a typical SCSI device with a selectable SCSI ID switch: 7 Terminate the last (or only) SCSI device connected to the SlimSCSI 1480. Read the device documentation if you are not sure how to terminate the device, or refer to Terminating the SCSI Bus on page 11. 8 Be sure that at least one external SCSI device provides SCSI bus termination power or that the last device on the bus supplies termination power to itself.
Installing the SlimSCSI Windows 95 Driver Installing the SlimSCSI Windows 95 Driver 1 If Windows 95 is not already running, start it now. 2 If the SlimSCSI 1480 is not already inserted in the CardBus slot, insert it now. Then wait until Windows 95 finishes building the database information for the adapter. The Windows 95 Update Device Driver Wizard starts automatically.
SlimSCSI 1480 User’s Guide Using the SlimSCSI Adapter Hot Plugging After you install the APA-1480 driver for the SlimSCSI 1480, you can insert or remove the SlimSCSI 1480 at any time except when data is being transferred on the SCSI bus. This is called hot plugging. (You can tell that data is being transferred if the SCSI device activity light is on.
Using the SlimSCSI Adapter Caution: Your PC may hang if you remove the adapter before the message appears. When you insert the SlimSCSI 1480 adapter while Windows 95 is running, Windows 95 detects the adapter and the device(s) connected to it. (Be sure the devices are powered before you insert the adapter!) Controlling the SCAM and Ultra Features ■ SCAM stands for SCSI Configured AutoMatically, a feature that lets the PC automatically assign SCSI IDs to SCSI devices when it boots.
SlimSCSI 1480 User’s Guide 4 Double-click SCSI Controllers. The System Properties dialog box now looks like this: 5 Double-click Adaptec APA-1480 CardBus UltraSCSI Adapter. 6 Select the Settings tab in the dialog box. In the Adapter Settings box type one of these commands: ■ To disable the Ultra option, type: /no_ultra ■ To disable the SCAM option, type: /no_scam ■ To disable both SCAM and Ultra options, type: /no_ultra /no_scam Be sure to include a space between the options, as shown.
Using the SlimSCSI Adapter The dialog box will now display the options you have entered, as shown below: Note: To enable an option that you previously disabled, return to the Adapter Settings box and delete one or both commands. 7 Click OK. 8 When you are prompted to restart your computer, click Yes.
SlimSCSI 1480 User’s Guide Understanding SCSI SCSI (pronounced “scuzzy”) stands for Small Computer Systems Interface. SCSI is an industry standard computer interface for connecting SCSI devices (such as hard disk drives, CD-ROM drives, and scanners) to a common SCSI bus. A SCSI bus is an electrical pathway consisting of a SCSI adapter (such as the SlimSCSI adapter) installed in a computer and one or more SCSI devices. SCSI cables are used to connect the devices to the SCSI card.
Understanding SCSI Terminating the SCSI Bus To ensure reliable communication on the SCSI bus, terminators must be installed (or enabled) on the devices at the physical ends of the SCSI bus. The terminators on all devices between the physical ends must be removed (or disabled). Termination on the SlimSCSI 1480 is permanently enabled, since it is always at one end of the SCSI bus. There are various methods for terminating disk drives and other SCSI devices.
SlimSCSI 1480 User’s Guide Connector Types Several different types of SCSI connectors are used on SCSI devices, and each type requires a different kind of cable. The following diagrams illustrate the different kinds of SCSI connectors: SCSI-2 High-density 50-pin Connector Typically used with high-performance CD-ROM drives, hard disk drives, Jaz drives, and Plug and Play devices.
Troubleshooting Troubleshooting Most problems with the SlimSCSI 1480 result from errors in preparing and connecting the SCSI devices to it. If you have problems, check the items below. Note: If you have problems with a specific SCSI device when other SCSI devices are working correctly, contact the manufacturer of the problem device for troubleshooting information. General Hardware Troubleshooting ■ Be sure all SCSI cables and power cables are properly connected and all SCSI devices are powered.
SlimSCSI 1480 User’s Guide General Software Troubleshooting Some portable PCs have a Suspend/Resume button to save power without turning off the PC. If your PC hangs (that is, freezes, or stops responding to keystroke commands) after you use this button to resume activity, it may indicate that you need to update the pccard.vxd and cbss.vxd files. Follow these steps to update these files and eliminate the hang problem: 1 In Windows 95, click the Start button, then click Run.

SlimSCSI 1480 User’s Guide 4 Double-click the System icon, then select the Device Manager tab. 5 Double-click SCSI controllers. The driver for the SlimSCSI adapter is listed as Adaptec APA-1480 CardBus UltraSCSI Adapter. ■ If the driver is listed, this means it is loaded properly. ■ If the driver is listed but has an exclamation mark inside a yellow circle, it is in a problem state (usually indicating a conflict with other hardware using the same resources.
Troubleshooting 3 Follow the onscreen instructions. If Windows 95 does not detect the SlimSCSI 1480, run the Add New Hardware Wizard again: 1 Double-click Add New Hardware in the Control Panel. 2 Select No on the second screen of the wizard. 3 Select SCSI controllers on the next screen. 4 Select the model of your Adaptec SCSI adapter.
