Installing Your Controller

Configuring Device IDs

The SCSI specification allows up to seven SCSI devices (and a controller) to be

connected to a single 8-bit SCSI bus. A Wide SCSI bus can support up to 15 devices

and the controller.

All SCSI devices, including the controller, must be assigned a unique SCSI ID. SCSI

IDs, which are typically set using jumpers or switches on peripheral devices, can be

assigned any number from 0 to 7 for 8-bit SCSI devices or 0 to 15 for Wide SCSI

devices.

Set the SCSI ID of each SCSI device attached to the controller to a unique ID number

between 0 and 6. The Adaptec SCSI RAID controller is set to ID 7 by default (most

SCSI controllers use ID 7). Wide SCSI devices can also use SCSI IDs 8 through 15.

SCSI IDs can be duplicated on the same controller if the devices using the same ID

are not attached to the same bus.

If necessary, the Adaptec SCSI RAID controller ID can be changed to any ID 0

through 7. You can use SMOR to change the controller SCSI ID.

IMPORTANT:

Changing the controller ID is not recommended. You should leave the Adaptec

SCSI RAID controller set at SCSI ID 7.

Installation

The following sections describe how the components of your Adaptec SCSI RAID

controller are assembled. Use these instructions in the event you need to add or

remove a component.

Installing Cache Memory Modules

Adaptec SCSI RAID controllers support up to 128 MB of cache using onboard

memory sockets. For specific information about memory modules for cache memory,

refer to “Cache Memory” in Chapter 2, “About Your New Controller.”
