36 Installing the Media Library in a Back-to-Back Configuration
Active Archive Appliance (A3) v6.5 PowerFile Confidential Racking and Installation Guide
•
Install the Archive Engines in the middle of the rack, between two or more Media Libraries.
This accommodates the length of the cable connections to the Media Libraries. For example,
one Archive Engine should face the back and the other should face the front.
• Install two inner rails on each Media Library; one on the right side and one on the left side of
the chassis. Pre-installed keyhole screws are provided on the chassis at the required
locations for the rail attachment.
• Install two outer rails facing the front of the rack, and two outer rails facing the rear of the
rack to accommodate the front and rear Media Libraries, respectively.
• Ensure that the outer rails for the front and rear Media Libraries are at the same relative
rack-mounted unit (RMU) position on the rack, while allowing ample room for stacking the
chasses. This ensures that the Media Libraries are balanced and level with each other in the
rack.
