Replacing an Internal System Director Drive
There are two system drives installed in the Avid ISIS Engines. The two drives are mirrored and
accessible from the rear of the Engine. If you have a failure on either one of the two system
drives you can pull the failed drive out of the Engine and install a replacement without turning
off the Avid ISIS Engines. The Avid ISIS continues to run properly if one of the two system
drives are removed.
As soon as you install a replacement system drive into the vacant system drive slot, the system
begins the process of creating a mirror of the original drive on the new drive. All Avid ISIS
operations continue to run uninterrupted.
n
The drive carriers for the system drives are locked to avoid them from opening during shipment.
The plastic drive carrier key is mounted on the rear of the Engine beside the system drives.
To replace the System Director drive:
1. Remove the failed drive from the front of the System Director by releasing the drive latch on
the front of the drive and pulling the drive from the chassis.
2. Insert the new drive completely into the open drive slot and close the drive latch.
The new drive initiates and completes the repair with no other intervention.
