Pre Installation

This section describes the recommended location and environment required for best performance of the Onyx FHM and the materials and tools needed to install the Onyx FHM.

Installation Location

The Onyx FHM is designed to be installed in either a 19-inch standard rack or chassis that conforms to EIA-310 dimensions, or to be mounted flush to a wall.

When front mounted in a 19-inch Rack or Chassis, the rack or chassis must have a front-to-back clearance (depth) of no less than 10.9 inches (277mm).

The Onyx FHM is air cooled by its integrated fans and relies on intake air that has a temperature of -40°C to 65°C. Ideally, the rack/chassis shall reside in an indoor climate-controlled environment. Additionally, if a 19” server chassis is utilized, adequate airflow through the chassis and clearance of at least 6 inches (153mm) from the front doors of the chassis must be ensured.

Do not install the Onyx FHM where the relative humidity of the surrounding air can exceed 95% or where it will be exposed to falling or dripping water or other liquid contaminates.

To best ensure long-term performance of the Onyx FHM, install the device in a location with minimal dust in the environment, or where dust mitigation (air filtering) is present.
