Sun Disk Shelf

Precautions

Observe the following cautions when installing a Sun Disk Shelf into a rack using the rail assembly in the bolt-on rack mount kit. Note that if your rack mount kit shipped with installation instructions, use those instructions instead.

• Always load equipment into a rack from the bottom up so that it will not become top-heavy and tip over. Deploy the anti-tip bar to the prevent the rack from tipping during equipment installation.

• Ensure that the temperature in the rack does not exceed the controller's maximum ambient rated temperatures. Consider the total airflow requirements of all equipment installed in the rack to ensure that the equipment is operated within its specified temperature range.

Prerequisites

Refer to the poster that shipped with the product or the Sun ZFS Storage 7x20 Service Manual located on http://wikis.sun.com/display/fishworks for an overview of your disk shelf.

Tools and Equipment Needed

To install the shelf, you need the following tools:

• You will need a No. 2 Phillips head screwdriver that is a minimum of 4 inches long.

• A mechanical lift is highly recommended because the chassis can weigh between 91-170 lbs. (42-77kg). At least three people are required: two to install the shelf or controller and one spotter to engage the rails.

• :If a mechanical lift is not available, remove the power supplies, SIM boards and hard disk drives to reduce the weight, see Sun Disk Shelf Maintenance Procedures and Controller Maintenance Procedures for instructions included in the Sun ZFS Storage 7x20 Service Manual on http://wikis.sun.com/display/fishworks.

Use one of the following racks for the Sun Disk Shelf.

• Sun Rack 900/1000 cabinet

• Sun Fire cabinet

• Sun StorEdge Expansion cabinet

• Sun Rack II 1042/1242 cabinet

• Any 19-inch wide, 4-post, EIA-compatible rack or cabinet with a front-to-back depth between vertical cabinet rails of 61 cm to 91 cm (24 in. to 36 in.). The cabinet can have threaded or unthreaded cabinet rails.

Position the rack where the shelf is to be installed adjacent to the rack where the controller is installed, if separate. Stabilize the cabinet and lock the casters.

Tasks

Sun Disk Shelf Tasks

Installing the Sun Disk Shelf into the Rack Slide Rails

1. Starting at the bottom of the cabinet, locate the appropriate rack unit (RU) height. Install Disk Shelves below controllers to prevent rack from tipping. The Sun Disk Shelf requires four standard mounting units (4RU) of vertical space in the cabinet.
2. If you are using a universal 19-inch or Sun Rack II cabinet, snap an M6 square cage nut into the 4U location where you will be installing the system. Install in the top and bottom holes.
3. Install appropriate rail plates in four locations on the rack (2 front and 2 back) by aligning the two pins on the rail plate with holes on the cabinet rails.
4. Insert M6 screws in the top and bottom holes of each rail plate and tighten (8 total places).
5. Install each rail by first aligning the front pins of the rack adapter plates with corresponding holes in the front of the rail, then adjust the rail to fit the rack and insert the pins from the rear rack adapter plates into the corresponding holes of the rail.
6. Install four 8-32 screws into the four remaining front and rear holes of each rack rail (16 total).
7. Using a mechanical lift or two people, one at each side of the shelf or controller, carefully lift and rest the shelf on the bottom ledge of the left and right rails. The following graphic illustrates the chassis insertion.

   

8. Carefully slide the shelf into the cabinet until the front flanges of the shelf touch the vertical face of the rack.
9. Tighten the captive screws on each side of the front of the shelf to secure the shelf to the rack.
10. At the back of the disk shelf, slide a system locking clip onto each lower corner of the chassis.
