Hardware Installation
Site Preparation
Attention
Improper installation of the chassis can expose personnel to high voltages,
risking the possibility of injury or death. Before installing TurboStack
hubs, read the See Electrical Safety and Installation Requirements on
page i.
Location
A TurboStack hub can operate as a standalone product, or installed in a
chassis or in a 19-inch rack.
Ventilation
The site must have adequate ventilation to provide an operating
environment consistent with TurboStack specifications. Hubs have
internal fans to aid in cooling. Chassis models are also equipped with fans.
For the fans to function correctly, you must not block the ventilation
openings located on the sides of the chassis.
Attention
Maximum ambient temperature is 40
o
C with a department concentrator
chassis.
Power
Power connections for each unit should be able to provide 50 watts at 120
VAC for U.S.A. versions or 240VAC for international versions. It is
advisable to use dedicated power circuits or power conditioners to supply
power to the network devices. This aids in isolating the network
equipment from electrical power “noise.”
