Before You Install
WARNING
: The PoLRE switch can be installed in any indoor location in all countries except in
Finland, Norway and Sweden, where, in these three Nordic countries, it must be installed in a
restricted access location .
The location has to meet the following size, distance and environmental criteria.
Size Requirements
Select a standard 19" equipment rack or, for a standalone PoLRE switch, a flat, stable surface capable of
supporting the size and weight of the PoLRE switch, its installable components and cabling. Refer to PoLRE
Switch Dimensions, page 4.
Ensure that you have enough rack space for all equipment. Shelves and rear supporting brackets are not
mandatory. See Installing the Switch in a Rack, page 21.
Physical Location Requirements
Power
The PoLRE switch must be placed within 6 feet of an available AC power source. Do not use an extension
cord to connect the equipment to a power outlet.
Ventilation
To ensure proper ventilation of the PoLRE switch, leave at least 2 inches of unobstructed space on all
sides of the switch. If the fans are blocked, the unit could overheat. Refer also to Operating/Storage
Environment, page 5.
Downlink
The Phylink adapters can be installed up to 1200' (365m) away from the PoLRE switch.
