■
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
SANnet II 200 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.
