caution icon

Caution - Electrostaticdischarge can damage sensitive components. Touching the array or its components without using a proper ground might damage the equipment. To avoid damage, use proper antistatic protection before handling any components.




Cabinets, Racks, and Rail Kits

The Sun StorageTek 5220 NAS Appliance can be installed in the Suntrademark Rack 900, the Suntrademark Rack 1000, or third-party racks that comply with the requirements. Although the system is installed in a single cabinet or rack, the appliance and the back-end storage units require different rails to support them.



Note - A cabinet is a rack with a door and the two terms are used interchangeably.



Requirements for Racks and Cabinets

Requirements to support installation of the storage system:

Rack density varies widely based on systems installed, power distribution installation (in-cabinet, external), power source (single-phase, three-phase), and whether redundant power is required. Some rack vendors do not support a fully-loaded rack because of the amount of power required. For power specifications, refer to Appendix A.

Requirements for Rail Kit



Note - Not all third-party racks are compatible with these slide rail kits.



Slide Rail Kit for the Appliance

The Sun StorageTek 5220 NAS Appliance is supported with the slide rail kit (370-7669-02) and cable management arm (370-7668-02). The slide rail kit contains four-point mounted slide rails and is designed to enable the Sun StorageTek 5220 NAS Appliance to be installed in the Sun Racktrademark 900, the Sun Rack 1000, and other ANSI/EIA 310-D-1992 or IEC 60927 compliant racks. No other kits are available to allow two-point, front-mount, or mid-mount installation.

The slide kit includes hardware that enables mounting to any of the following types of rails:

Universal Rail Kit for Back-End Storage

Use the universal rail kit to mount the controller and expansion units in any standard Sun cabinet, such as the Sun Rack 900/1000 cabinet.


Preparing for the Installation

Use the following procedures to prepare for installation:

Preparing the Cabinet



Note - The rack must have an AC power disconnect. This power source disconnect must be easily accessible, and it must be labeled as controlling power to the entire rack, not only to the appliance



Be sure the location of the cabinet or rack complies with the following requirements and that it has been installed as described in its installation instructions:

Before you begin mounting the rail kits, do the following:

1. Stabilize the cabinet as described in the cabinet documentation.

2. If the cabinet has casters, make sure the casters are locked to prevent the cabinet from rolling.

3. Remove or open the front panel.

4. Remove or open the vented back panel.



Note - Sun Microsystems makes no warranties or guarantees as to fit, form, or function of the Sun StorageTek 5220 NAS Appliance system installed in third-party racks or cabinets. It is the customer's responsibility to ensure that the rack or cabinet can house the Sun StorageTek 5220 NAS Appliance system in all conditions that might exist. All racks and cabinets must comply with local building and construction codes.



Proper Grounding Technique

You must maintain reliable grounding of this equipment. Review specifications in Appendix A to determine the appropriate AC branch circuit size for the quantity of units in your configuration and your operating voltage. Always follow your local electrical codes for loading circuits.



caution icon

Caution - The controller unit and expansion units contain several components sensitive to static-electrical discharge. Surges of static electricity (caused by shuffling your feet across a floor and touching a metallic surface, for example) can cause damage to electrical components. It is important that proper grounding techniques be observed.



Avoiding Damage to Internal Components



caution icon

Caution - Do not power on any units until after you have connected the Sun StorageTek 5220 NAS Appliance to the network.



Grounding the Rack During Installation

The safe ground conductor provides proper grounding only for the Sun StorageTek 5220 NAS Appliance. You must provide additional proper grounding for the rack and other devices installed in it.

Review specifications in Appendix A to determine isolation and continuous power requirements.

Planning the Installation

At a minimum, the system has an appliance and the controller unit. Your system can have one or two expansion units, installed now or at a later date. Plan the placement of the rails carefully because they are spaced differently, depending on whether you are installing a unit or an appliance.

In general, the installation is accomplished in the following order:

1. Install the universal slide rail kit for the controller unit, starting at the bottom of the rack.

2. Install the universal slide rail kit for each expansion unit, starting above the controller unit.

3. Mount the controller unit at the bottom of the cabinet.

4. Mount each expansion unit, from the bottom up.

5. Install the slide rails for the appliance.

6. Install the cable management kit.

7. Mount the appliance.

8. Install the power cords.



caution icon

Caution - The controller and expansion units must be installed in the cabinet starting from the bottom up to distribute the weight correctly in the cabinet. The appliance is installed last. Uneven loading of the rack can cause dangerous instability.





Note - Some procedures require two people to complete.
