Cabinet and Rack Specifications |
The Sun StorageTek 6140 Array can be installed in any NEBS-compliant, standard 19" 4-post cabinet with 24-26" spacing between posts. This includes all StorEdge Expansion, SunFire, and Sun Rack 900/1000 cabinets. This chapter describes the physical, environmental, and electrical requirements for these cabinets, as follows:
To ensure safe and proper operation of the system, and ease of maintenance, make sure that all of these requirements have been met before beginning the installation of the cabinet.
This section describes the physical, electrical, and environmental requirements for the Sun StorEdge Expansion cabinet.
The floor area at the installation site must provide enough stability to support the weight of the cabinet and installed trays, sufficient space for installation and servicing of the cabinet and components, and sufficient ventilation to provide a free flow of air to the cabinet.
TABLE 2-1 provides the physical dimensions of the Sun StorEdge expansion cabinet.
TABLE 2-2 lists cabinet clearance and service access requirements.
The total weight of a populated Sun StorEdge Expansion cabinet depends on the number and type of modules installed in the cabinet. TABLE 2-3 lists the weight of an empty cabinet and the maximum weight of each component. Use these weights to estimate the total weight of your system, based on the number of modules installed in the cabinet. Record the total weight in an easy-to-find place to reference when checking flooring load or elevator weight restrictions.

This section describes the environmental conditions that are prerequisite to installing the cabinet.
TABLE 2-4 lists operating and nonoperating temperature, relative humidity, and altitude ranges for the Sun StorEdge Expansion cabinet.
0.15 g on z-axis; 0.10 g on x- and y-axes; 5 to 500 Hz sinusoidal |
0.5 g on z-axis; 0.25 g on x- and y-axes; 5 to 500 Hz sinusoidal |
Cabinet airflow is from front to back. Allow at least 30 inches in front of the cabinet, and at least 24 inches behind the cabinet, for service clearance, proper ventilation, and heat dissipation.
The AC power sources must provide the correct voltage, current, and frequency specified on the module model and serial number label. The cabinet can run within the limits shown in TABLE 2-5.
This section describes the physical, electrical, and environmental requirements for the Sun Fire 6800 cabinet.
The floor area at the installation site must provide enough stability to support the weight of the cabinet and installed trays, sufficient space for installation and servicing of the cabinet and components, and sufficient ventilation to provide a free flow of air to the cabinet.
TABLE 2-6 provides the physical dimensions of the Sun Fire cabinet.
Sun Fire cabinets can be placed next to each other, without space between them, since there are no side clearance requirements during operation. However, if access is desired for removal of side panels, allow approximately 2 feet (60 centimeters) of space on each side.
TABLE 2-7 lists cabinet clearance and service access requirements.
The total weight of a populated Sun Fire cabinet depends on the number and type of modules installed in the cabinet. TABLE 2-8 lists the weight of an empty cabinet and the maximum weight of each component. Use these weights to estimate the total weight of your system, based on the number of modules installed in the cabinet. Record the total weight in an easy-to-find place to reference when checking flooring load or elevator weight restrictions.

This section describes the environmental conditions that are prerequisite to installing the cabinet.
TABLE 2-9 lists operating and nonoperating relative humidity, and altitude ranges for the Sun Fire cabinet. The table also provides the optimum operating condition in the recommended operating environment. Operating computer equipment for extended periods of time at or near the temperature or humidity extremes is known to significantly increase the failure rate of hardware components.
The air intake screens act as electro-magnetic interference (EMI) and radio frequency interference (RFI) filters, stopping both EMI and RFI emissions from the system. These screens are honeycomb screens, which also collect and trap dust and debris particles.
The Sun Fire cabinet's air intake screens require periodic inspection and cleaning. To prevent restricted airflow and possible equipment failure, inspect the air intake screens for debris and trapped particles every three months of operation. Consider the level of debris on the screens and surrounding area in the decision as to when to remove and clean the air intake screens.
The AC power sources must provide the correct voltage, current, and frequency specified on the module model and serial number label. The cabinet can run within the limits shown in TABLE 2-10.

This section describes the physical, electrical, and environmental requirements for the Sun Rack 900/1000 cabinets.
The floor area at the installation site must provide enough stability to support the weight of the cabinet and installed trays, sufficient space for installation and servicing of the cabinet and components, and sufficient ventilation to provide a free flow of air to the cabinet.
TABLE 2-11 provides the physical dimensions and weight of the Sun Rack 900-38, 900-36N, and 1000-38 cabinets.
The total weight of a populated Sun Rack 900/1000 cabinet depends on the number and type of modules installed in the cabinet. TABLE 2-12 lists the weight of an empty cabinet and the maximum weight of each component. Use these weights to estimate the total weight of your system, based on the number of modules installed in the cabinet. Record the total weight in an easy-to-find place to reference when checking flooring load or elevator weight restrictions.

This section describes the environmental conditions that are prerequisite to installing Sun Rack cabinets.
TABLE 2-13 lists operating and nonoperating temperature, relative humidity, and altitude ranges for the Sun Rack 900/1000 cabinets.
Cabinet airflow is from front to back. Allow at least 30 inches in front of the cabinet, and at least 24 inches behind the cabinet, for service clearance, proper ventilation, and heat dissipation.
The AC power sources must provide the correct voltage, current, and frequency specified on the module model and serial number label. The cabinet can run within the limits shown in TABLE 2-14.
