2.2 Installation environment requirements
It is necessary for 7360 ISAM FX and 7360 ISAM WM shelves to be installed in
GR-3108-CORE Class 1 Controlled Environments or Class 2 Protected Equipment
Outside Environments, such as specific buildings or structures, to ensure reliable
equipment operation.
2.2.1 General information on GR-3108-CORE Class 1 and
Class 2 environments
Equipment placed in GR-3108-CORE Class 1 environments is designed to be
protected from direct exposure to weather and environmental stresses.
A Class 1 environment location usually has the active means of controlling the
temperature within its defined space, and to maintain a preset temperature range.
This control may be achieved through thermostat-controlled fans, refrigeration units,
heat exchangers, coolers, or heaters.
Table 3 shows examples of what would or would not qualify as a Class 1 controlled
protected environment.
Table 3 Class 1 controlled protected environments
The 7360 ISAM FX and 7360 ISAM WM equipment is designed to comply with
GR-3108-CORE Class 2 operating, storage, humidity, altitude, and fire resistance
requirements when installed in an OSP environment.
Danger — EMC/ESD requirements.
Ensure that the EMC/ESD conditions meet GR 1089 CORE
[35], GR-499-CORE [37].
Follow the antistatic procedures when handling units.
Most 7360 ISAM FX plug-in units and powered equipment
contain devices susceptible to electrostatic discharge (ESD)
that can damage circuitry in unconnected conditions.
Correct example of a Class 1 controlled protected
environment
Incorrect example of a Class 1 controlled protected
environment
A weather-protected, flood-resistant roofed structure
with closed, protective walls, and having active
temperature and humidity control.
A roofed structure with open walls.
