Cabinet Specifications and Site Requirements

C H A P T E R 2

This chapter describes the physical, environmental, and electrical requirements for the Sun Rack 1000-38 (STK5800) cabinet, which is the cabinet used for the Sun StorageTek 5800 System.

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.

To ensure safe and proper operation of the system, and ease of maintenance, make sure that all of these requirements are met before using the cabinet. It contains the following sections:

Dimension and Weight

TABLE 2-1 provides the physical dimensions of the Sun Rack STK5800 cabinet.

TABLE 2-1 Sun Rack STK5800 Cabinet Dimensions
Dimensions	Height	Width	Depth
American	74 in.	23.5 in.	35.4 in.
Metric	188 cm	59.7 cm	89.9 cm

A fully loaded Sun Rack 1000-38 (STK5800) cabinet has a maximum weight capacity of 1500 pounds (680.4 kilograms). The total weight of your Sun Rack STK5800 cabinet depends on the number and type of components installed in the cabinet. TABLE 2-2 displays the weights of each different configuration. Use these weights to estimate the total weight of your system, based on the number of components installed in the cabinet. Record the total weight in an easy-to-find place to reference when checking flooring load or elevator weight restrictions.

TABLE 2-2 Sun Rack STK5800 Cabinet and Component Weights
Component	Total Weight
8-node cell (nodes, switches and cables)	705 lbs (319.8 kgs)
16-node cell (nodes, switches and cables)	990 lbs (449.1 kgs)
Dual cell (nodes, switches and cables)	1265 lbs (573.8 kgs)

Table form to compute the weight of the componants by multplying the quantity times the weight of each componant. Componants include the cabinet, chassiss, controller, controller tray, expansion tray, power supply, and disk drives.

Environmental Requirements

This section describes the environmental conditions that are prerequisite to installing Sun Rack cabinets.

Temperature, Humidity, and Altitude

TABLE 2-3 lists operating and nonoperating temperature, relative humidity, and altitude ranges for the STK5800 rack.

TABLE 2-3 Cabinet Temperature, Humidity, and Altitude
Specification	Operating	Nonoperating
Temperature	41˚F to 95˚F (5˚C to 35˚C)	-45.4˚F to 154.4˚F (-43˚C to 68˚C)
Relative humidity (RH)	7% to 93% noncondensing	93% noncondensing at 104˚F (40˚C) for 5 days
Altitude	0 to 10498.7 feet (0 to 3.2 km) at 104˚F (40˚C)	0 to 40,026.2 feet (0 to 12.2 km) at 32˚F (0˚C) for 4 hours

If you plan to operate a system at an altitude between 3280 ft. to 10,000 ft. (1000 m to 3048 m) above sea level, lower the environmental temperature 3.3˚F (1.7˚C) for every 3280 ft. (1000 m) above sea level. TABLE 2-4 lists the acceptable humidity ranges in which the 5800 system is designed to operate.

TABLE 2-4 5800 System Relative Humidity (RH), Noncondensing

Specification	Maximum Rate of Change per Hour
Operating range	20% to 80%
Storage range	10% to 93%
Transit range	5% to 95%
Maximum dew point	79˚F (26˚C)
Maximum gradient	10% per hour

Airflow and Heat Dissipation

Rack airflow is from front to back. Allow at least 30 inches (76.2 cm) in front of the rack, and at least 24 (60.96 cm) inches behind the rack, for service clearance, proper ventilation, and heat dissipation.

Maximum Heat Output

The maximum heat output for the 5800 system is as follows:

Half cell: 2420 watts (8257 BTU/hr)

Full cell: 4420 watts (15082 BTU/hr)

Dual cell: 8840 watts (30163 BTU/hr)

TABLE 2-5 lists the remaining power available for additional equipment in a rack when a 5800 system is installed in the rack.

TABLE 2-5 Remaining Power Available in Rack After 5800 System is Installed
Installed 5800 System	Power Available for Additional Equipment in Rack
Half cell	11660 watts
Full cell	9660 watts

Power Requirements

The AC power sources must provide the correct voltage, current, and frequency specified on the component model and serial number label. The cabinet can run within the limits shown in TABLE 2-6.

TABLE 2-6 Rack AC Power Requirements
Parameter	Requirements
Nominal voltages	200 to 240 VAC
Operating voltage	180 to 264 VAC
Frequency range	50 to 60 Hz Single Phase
Current	32A (2 x 16A) maximum
AC power plug	NEMA L6-20P (North American) IEC 309 16A 3-Position (International)
AC power receptacle	NEMA L6-20R (North American) IEC 309 16A 3-Position (International)
Power cords required	2 for half-cell and full-cell configurations 4 for dual-cell configurations

Network Requirements

Your network must include the following features to allow for successful installation and administration of the 5800 system.

If you want to administer the 5800 system using the command-line interface (CLI), the system from which you want to access the CLI must be running a secure shell (SSH) client.

If you want to administer the 5800 system using the graphical user interface (GUI), you must have a Java-enabled web browser on your network. Refer to the Sun StorageTek 5800 System Release Notes for versions of Java that are supported.

You must reserve three IP addresses on your network per half-cell or full-cell for data, administration, and service access.

There must be at least one Network Time Protocol (NTP) server available on the network.

If you want to have system alerts emailed to an administrator, you must have an email address available for this purpose and a Simple Mail Transfer Protocol (SMTP) server available on the network.

None of the hosts located on the same subnet as the 5800 system can use the following addresses, which are reserved for use by the 5800 system:

10.123.0.1

10.123.0.2

10.123.45.1

10.123.45.100 through 10.123.45.116
