Hardware Installation
Site Preparation
Attention
Before installing AT-3600 Series hubs, read the safety installation
requirements starting on page i.
Location
A manageable AT-3600 Series hub can operate as a standalone product,
installed in a chassis, in a 19-inch rack, or on a desk top. You can combine
multiple hubs in an ATI chassis.
Ventilation
The site must have adequate ventilation to provide an operating
environment consistent with AT-3600 Series specifications. Chassis
mounting requires 191 mm (7.5 in.) ventilation clearance on all sides.
AT-3600 Series hubs have internal fans to aid in cooling. 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. It is customary to use dedicated power
circuits or power conditioners to supply power to the network devices. This
helps isolate the network equipment from electrical power “noise.”
Installing Hubs
This section contains two separate procedures for installing manageable
AT-3600 Series hubs:
❑
Standalone installation
❑
Installation in a managed hub configuration in a concentrator
chassis
