Overview

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
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.

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.

EMC/ESD requirements.
Danger —
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.
