How to Change an SCSI Controller

An SCSI controller is an internal hardware device that allows connectivity with SCSI hard drives. As the SCSI specification changes, it is important to maintain a current SCSI controller to allow for proper utilization of newly released hard drives. Whether replacing your SCSI controller to remain up to date, add additional SCSI ports or replace a failing controller, replacing an SCSI controller is an easy process any computer user can accomplish.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Motherboard-compatible SCSI controller

1. Disconnect your computer from any electrical sources and remove its side access case panel.

2. 
   SCSI controller card.

   Locate your old SCSI controller card found near the rear input/output panel of the computer's case.

3. Remove the SCSI controller from the motherboard interface slot by gently pulling perpendicular to the angle of the motherboard.

4. Insert your new SCSI controller into the now vacant interface slot.

5. Replace the computer's side access panel and re-establish any previously severed electrical sources.

6. Boot into your operating system and install any manufacturer-recommended software that may have accompanied the SCSI controller card.
