This guide explains how to install the AHA®-398x RAID adapters: the AHA-3980, AHA-3980W, AHA-3985, and AHA-3985W. The guide contains the information most users need to quickly install the RAID adapters. If you have never installed SCSI devices, you may prefer to use the detailed installation instructions in AHA-3980/3980W/3985/3985W User’s Guide. 1 READ THIS FIRST! Before you continue, make sure your system meets the following minimum requirements.
drives running under MS-DOS 5.0 and above. For information on supported devices, see the AHA-3980/3980W/3985/3985W User’s Guide.
Installing the AHA-398x WARNING: Unplug the computer from its power source before you begin. 1 Remove the cover from the computer case. 2 Locate an unused, unobstructed 5-volt PCI bus slot that supports bus mastering. AHA-398x host adapters require a full-length PCI slot. If your system has only one full-length slot and the slot is already occupied, you will need to move the existing board to another slot. 3 Remove the corresponding slot cover from the back of the computer chassis.
Do not replace the chassis cover or reconnect the power yet! 5 Connecting SCSI Devices You can attach internal devices to Channel A, B, or C. External devices must attach to Channel A, which is the only channel with an external connector. Remember, each channel on an AHA-3980 or AHA-3985 supports up to seven 8-bit devices. If you attach one SCSI device to the internal connector of Channel A, for example, you can attach up to six devices to the external connector—a total of seven devices on the channel.
– six meters (19.7 feet) if you are using 5 MByte/ sec asynchronous or synchronous data transfer rates Connecting Internal SCSI Devices The AHA-398x kit includes SCSI ribbon cables, each of which has several connectors for attaching internal devices to the AHA-398x. The connector at one end of each cable attaches to a passthrough terminator. This connector can still attach to a SCSI device, even with the terminator in place.
Connecting External SCSI Devices For each external SCSI device, obtain a high-quality external cable with a single-ended impedance range of 80–110 ohms. The cables should be at least 30 cm (11.8 inches) long. Use the cables to connect external SCSI devices as follows: 1 Attach the SCSI connector at one end of an external SCSI cable to the external Channel A connector (see the board layout on page 2). External cable connectors can be plugged-in only one way.
Setting SCSI IDs Assign each device on a channel, including the channel itself, a unique SCSI ID—no duplicate IDs are permitted on a channel. Allowable IDs are 0 through 7 for SCSI devices on the AHA-3980 and AHA-3985. On the AHA-3980W and AHA-3985W, allowable IDs are 0 through 15. ID 7 has the highest priority on the channel. The priority of the remaining IDs, in descending order, is 6 to 0, then 15 to 8. We recommend using the following IDs: ■ Leave the channel (RAID adapter) ID at the default, 7.
Note: If you own a previously purchased Adaptec AHA-3980/3985 RAID adapter with software version v.1.01 or earlier, you can obtain a free upgrade kit from Adaptec to add bootable array support to your adapter. Contact Adaptec Technical Support for this BIOS and software upgrade kit. The kit includes instructions on how to install the upgrade. 7 Changing AHA-398x Settings The AHA-398x has the factory default settings shown in the following table. These settings are correct for most computers.
Note: In the remaining steps, you are instructed to select items. To select an item, use the ↑ and ↓ keys to move the cursor to the item, then press the Enter key. 4 Select the channel you want to configure. 5 Select Configure/View Host Adapter Settings. 6 The Configuration menu appears, listing the basic settings for the SCSI bus interface. To display the individual device settings, select SCSI Device Configuration from the Configuration menu.
8 Troubleshooting Checklist Check the following items if you have problems installing or running the adapter and SCSI devices: ■ Did the AHA-398x BIOS sign-on message appear during bootup? If not, check the following items: – Is the AHA-398x properly seated? – Does your computer CMOS setup require you to enable PCI bus parameters (see your computer documentation)? If so, run the CMOS setup program and assign the parameters—usually IRQ, Enable PCI Slot, and Enable Master.
the drive or array has been selected as the boot device and that the boot partition is active. If you still have trouble, see the Troubleshooting section in the AHA-3980/3980W/3985/3985W User’s Guide. 11 A AAAA AAAA AA AAAA A AAAAAAAA AAAAAAAA AAAAAAAA AAAAAAAA AAAAAAAA AAAAAAAA AAAAAAAA AAAAAAAA AAAAAAAA AAAAAAAA AAAAAAAA AAAAAAAA AAAA AA A Document Title: AHA-3980/3980W/3985/3985W QuickAA A AA A AA A AA Reference: Hardware Installation A AA A AA Part Number: 510673-00, Rev.
