Site Preparation
Protection is typically achieved by deploying the product in a cabinet that is sealed
and is provided either with air-to-air heat exchangers or with air-conditioning and/or
heaters as required for the local climate. If the cabinet is the type that allows outside
air to ventilate the cabinet, it must have Hydrophobic Membrane filters, at the air inlet
and air exit, with all other parts properly sealed against outside contaminants and
moisture. Typically, cabinets that comply with Telcordia GR-487, Generic
Requirements for Electronic Equipment Cabinets, provide this level of protection.
The ambient air temperature must be within the specifications defined in
Table 5
For proper thermal performance, the following conditions must be met:
