Important Information About Ultra Wide SCSI Cards
Adding Internal Devices to the Ultra Wide SCSI Card Installed in Your Server
If you add an internal Ultra Wide SCSI device to your server's Ultra Wide SCSI bus, you need to assign it a SCSI ID number in the 8 to 15 range. Devices assigned to numbers 2 through 6 may not work reliably. For more information about the Ultra Wide SCSI-3 bus, see pp. 39-40 in Setting Up Your Macintosh Server.
Adding an Additional Ultra Wide SCSI Card to Your Server
If you want to connect external Ultra Wide SCSI devices to your server, you must install a second Ultra Wide SCSI card. You cannot connect any SCSI devices to the external 68-pin SCSI-3 connector on the PCI card that supports the internal hard disks. For more information, see pp. 66-67 in Setting Up Your Macintosh Server.
If you want to install a second Ultra Wide SCSI Card, follow these guidelines for best results:
- Use a single-channel card if possible.
- If you need to add a dual-channel Ultra Wide SCSI card, choose one with a bridge chip that routes interrupts.*
