This chapter outlines the site-planning requirements and basic safety requirements for the installation and use of Sun StorEdge 3320 SCSI arrays. Customers are asked to complete a Section 2.8, Preinstallation Worksheet and to prepare the site for installation according to the worksheet details and the specified site-planning requirements.
Review the details of this chapter before installing a Sun StorEdge 3320 SCSI array. Topics covered in this chapter are:
| Note - Refer to the Sun StorEdge 3320 SCSI Array Release Notes for the current lists of supported operating systems, host platforms, software, and qualified cabinets.
|
2.1 Customer Obligations
The customer is obliged to inform Sun Microsystems, Inc. of any and all ordinances and regulations that would affect installation.
|
Caution - When selecting an installation site for the Sun StorEdge 3320 SCSI array, choose a location that avoids excessive heat, direct sunlight, dust, or chemical exposure. Such exposure greatly reduces the product’s longevity and might void your warranty.
|
The customer is responsible for meeting all government codes and regulations concerning facilities. The customer is also responsible for compliance with the following requirements:
- Meet all local, national, and international codes covered in this specification. The subjects covered include fire and safety, building, and electrical codes.
- Document and inform Sun Microsystems, Inc. of any deviations from this specification.
2.2 Safety Precautions
For your protection, observe the following safety precautions when setting up your equipment:
- Follow all safety precautions and requirements specified in the Sun StorEdge 3000 Family Safety, Regulatory, and Compliance Manual.
- A fully loaded array weighs over 57 pounds (26 kilograms). Use two people to lift the array to avoid injury.
- Follow all cautions and instructions marked on the equipment.
- Ensure that the voltage and frequency of your power source match the voltage and frequency inscribed on the equipment’s electrical rating label.
- Never push objects of any kind through openings in the equipment. Dangerous voltages may be present. Conductive foreign objects could produce a short circuit that could cause fire, electric shock, or damage to your equipment.
- To reduce the risk of electric shock, do not plug Sun products into any other type of power system. Sun products are designed to work with single-phase power systems having a grounded neutral conductor. Contact your facilities manager or a qualified electrician if you are not sure what type of power is supplied to your building.
- Your Sun product is shipped with a grounding-type (three-wire) power cord. To reduce the risk of electric shock, always plug the cord into a grounded power outlet.
- Do not use household extension cords with your Sun product. Not all power cords have the same current ratings. Household extension cords do not have overload protection and are not meant for use with computer systems.
- Do not block or cover the openings of your Sun product. Never place a Sun product near a radiator or heat register. Failure to follow these guidelines can cause overheating and affect the reliability of your Sun product.

2.3.1 Electromagnetic Compatibility (EMC)
The following is required for all installations:
- All AC mains and supply conductors to power distribution boxes for both the rackmounted array and the desktop array must be enclosed in a metal conduit or raceway when specified by local, national, or other applicable government codes and regulations.
- The supply conductors and power distribution boxes (or equivalent metal enclosure) must be grounded at both ends.
- The supplied arrays require voltages within minimum fluctuation.
- The facilities voltage supplied by the customer must maintain a voltage of not more than (+/-) 5 percent. The customer facilities must provide suitable surge protection.
2.4 Electrical and Power Specifications
All Sun StorEdge 3320 SCSI arrays require two independent power sources. Each array has two power-supply-and-fan modules for redundancy.
Each Sun StorEdge 3320 AC array requires two 115-VAC/15A or two 240-VAC service outlets. All AC power supplies are autoranging and are automatically configured to a range of 90 to 264 VAC and 47 to 63 Hz. There is no need to make special adjustments.
Each DC array requires two -48 VDC service outlets, and has an input voltage range of -36 VDC to -72 VDC.
| Note - To ensure power redundancy, connect the two Sun StorEdge 3320 SCSI power modules to two separate circuits (for example, one commercial circuit and one UPS).

2.6 Layout Map
It is helpful to create a sketch or layout map to indicate the exact location for the Sun StorEdge 3320 SCSI array installation as well as the location of the hosts, console, and Ethernet connections that will be connected to it.
As you lay out the components, consider the cable lengths that will be used.
2.6.1 Rack Placement
Follow these guidelines when preparing a rackmount placement for your system.
- Ensure that the floor surface is level.
- Leave enough space in front of the rack to access components for servicing.
- Leave enough space in back of the rack to access components for servicing.
- Keep power and interface cables clear of foot traffic. Route cables inside walls, under the floor, through the ceiling, or in protective channels or raceways.
- Route interface cables (excluding fiber-optic cables) away from motors and other sources of magnetic or radio frequency interference.
- Stay within the cable length limitations.
- Provide two separate power sources for the array. These power sources must be independent of each other, and each must be controlled by a separate circuit breaker at the power distribution point.
2.6.2 Tabletop Placement
Sun StorEdge 3320 SCSI arrays can be positioned on a desk or a table. Follow these guidelines when preparing a tabletop placement for your system.
- Choose a desk or a table that can support 57.2 pounds (26 kg) for one fully-configured array or 116 pounds (52 kg) for two arrays.
- Do not place the array on the edge of the table. Set the array so that at least 50 percent of the array is inside the table or desk leg support area. Failure to do this might cause the table to tip over.
- Leave enough space in front and in back of the array to access components for servicing. To remove the components requires a clearance of 15 inches (37 cm) in front and in back of the array.
- Provide a minimum space of 6 inches (15 cm) in front and in back of the array for adequate airflow.
- Keep power and interface cables clear of foot traffic. Route cables inside walls, under the floor, through the ceiling, or in protective channels or raceways.
- Route interface cables away from motors and other sources of magnetic or radio frequency interference.
- Stay within the cable length limitations.
- Ensure that the operating system for the array does not exceed the specifications.
- Use two people to lift the array to avoid injury. The array can weigh up to 57.2 pounds (26 kg).
- Do not place the array in a vertical position. Place the array horizontally.
- If you are installing multiple arrays you can stack up to five arrays on top of each other. Do not stack more than five arrays in one stack.
- Provide two separate power sources for the array. These power sources must be independent of each other, and each must be controlled by a separate circuit breaker at the power distribution point.
2.7 Console and Other Requirements
A console with at least one serial port connection is necessary for installation and configuration of your Sun StorEdge 3320 SCSI array. Once you have configured your array with an IP address, an Ethernet port can also be useful for configuring the array.
| Note - Sun StorEdge 3000 family arrays require at least CAT-5 Ethernet cable.
