## Changing the SCSI transfer speed

(Startable-CD mode only.)

Use this action to change the SCSI transfer speed.

1. Click a SCSI channel from the Main Tree.
2. Click Actions --> Change the SCSI transfer speed.
3. Click a transfer speed from the menu. The following choices are available:
   - Optimal

   > This value is available if your controller supports it; otherwise, Optimal does not appear in the menu. Optimal is the default value. When the transfer speed is set to Optimal, the ServeRAID controller determines the best transfer speed, based on the types of SCSI drives and storage enclosures in use.

   - Ultra160 SCSI
   - Ultra2 SCSI
   - UltraSCSI
   - Fast SCSI-2
   - SCSI-2
   - SCSI-1

   > This value is available if your controller is set to SCSI-1; otherwise, SCSI-1 does not appear in the menu.
