Chapter 2 Site Planning 2-5

■ Route interface 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

SANnet II 200 FC, SATA, and SATA SE 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 60 pounds (27 kg) for each fully

configured array you plan to place on it.

■ Do not place the arrays 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 over 60 pounds

(27 kg).

■ Do not place the array in a vertical position. Place the array horizontally.

■ If you are installing more than one array, you can stack up to five arrays on top of

each other. Do not stack more than five arrays together.

■ 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 FC, SATA, or SATA SE array. Once you have configured your

array with an IP address, an Ethernet port can also be useful for configuring the array.
