Oracle^® ZFS Storage Appliance Installation Guide

Installing a DE2-24P Disk Shelf

Use the following procedure to install an Oracle Storage Drive Enclosure DE2-24P, which requires two standard mounting rack units (2RU), or six rack holes, of vertical space in the cabinet.

Before You Begin

• Review Prerequisites for Installation and Overview of Disk Shelves.

• To prevent the cabinet from tipping, always load the heaviest equipment, which are disk shelves, starting from the bottom of the cabinet.

• To best prepare for cabling disk shelves to controllers, now and in the future, mount controllers in the middle of the cabinet.

• Screws are not provided for installation into a cabinet with M6-sized threaded holes.

1. Extend all anti-tilt and stabilization devices from the bottom of the rack.
2. Locate the appropriate rack unit (RU) height, which is six rack holes, starting from the bottom on the cabinet. If your rack is an unthreaded universal 19-inch, Sun Rack II, or Oracle Rack Cabinet 1242 cabinet:
   1. Position the front rail location pegs fully inside the appropriate holes in the front of the rack.

      The rail flange must be inside of the cabinet flange, and the rail label facing the inside of the cabinet.

   2. Insert and tighten one screw through the front of the rack and into the top hole in the rails.
   3. Adjust the rail lengths to fit, and position the rear rail location pegs in the corresponding rear rack holes.
   4. Insert and tighten one screw through the back of the rack and into the back of the rails.
   
   

3. If your rack is a threaded universal 19-inch cabinet:
   1. Use the T20 Torx driver to remove the rail location pegs from the front and rear of the rails.
   2. Use the supplied wrench to insert two pins into each end of the rails, in the same location where the location pegs were removed.
   3. Position the front of the rails inside the cabinet, with the rail flange inside of the cabinet flange, and the rail label facing the inside of the cabinet.

      The pins should be fully located within the rack holes.

   4. Insert and tighten one screw through the front of the rack and into the top hole in the rails.
   5. Adjust the rail lengths to fit, and locate the rear pins inside the corresponding rear rack holes.
   6. Insert and tighten one screw through the back of the rack and into the back of the rails.
   
   
4. Using a mechanical lift or two people, one at each side of the disk shelf, carefully lift and rest the shelf on the bottom ledge of the left and right rails. Do not lift using the power supply with fan module handles.
   
5. Carefully slide the shelf into the rails until it is fully seated within the cabinet. The spotter, using a flashlight, should ensure that the shelf is fully seated within the rails. If removing the shelf to reseat it, support it at all times.
6. Install one long patchlock screw per rail to secure the rear of the shelf to the rear of the rack. If the screw cannot be inserted, the shelf might not be fully seated within the rails.
   
7. Remove the front side caps, install one screw into each front side, and replace the caps.
