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

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.”
