How to add a 15 Drive Unity Disk Array Enclosure (DAE) for a Unity system

This video demonstrate a addition procedure of a 15-Drive Unity Disk Array Enclosure (DAE) for a Unity system..

This video shows how to add a 15-drive disk array enclosure, or DAE, to an existing rack-mounted Unity system. Unity DAEs, provide expanded storage capacity for Unity storage systems. Before you begin: ensure that you always wear proper electrostatic discharge, or ESD, protection when servicing the system.

To begin this process, first install the rails in the rack. Next, mount the DAE into the rack. Lift the DAE from the front of the rack, and carefully slide it into the installed rails. Then, use the four supplied screws to loosely fasten it to the front of the rack. When all four screws are secured in place, firmly tighten each one. If the DAE disks were shipped separately from the enclosure, you can install them in the enclosure now.

Use the provided mini-SAS HD expansion cables to connect the DAE to the Unity system. There are several cabling options that are described in the Unity documentation. This video demonstrates one of the most common cabling options. From the rear of the rack, connect a cable from the Port 0 connector on SP A of the Unity system, to the Port A connector on LCC A of the DAE enclosure.

Then connect a cable from the Port 0 connector of SP B of the Unity system, to the Port A connector on LCC B of the DAE enclosure. Then, plug in an AC or DC cord into the appropriate power connector on the DAE module, securing the power cord with the corresponding clips on the back of the DAE enclosure.

When your DAE enclosure is installed, cabled, and powered on, use Unisphere to validate that the DAE is connected to Unity. After logging into Unisphere, check for the new DAE in the Enclosures view, and verify the status is shown as ‘OK.’ You’ve just installed and configured your new DAE.
