Mounting the Unit
If installing the unit in a rack, install the rack-mount ears on the two sides of the front panel and mount the unit in a standard 19-inch rack cabinet. The unit is intended to be installed in one orientation only. The unit should be mounted so the front panel interface keys are to the left of the display area.
The NetClock unit will install into any EIA standard 19-inch rack. NetClock occupies one rack unit of space for installation, however, it is recommended to leave empty space of at least one rack unit above and below the NetClock unit to allow for best ventilation.
Rack mounting requirements:
- The maximum ambient operating temperature must be observed. See for the operating temperature range specified for the type of oscillator installed in your NetClock unit.
- If the NetClock unit is to be installed in a closed rack, or a rack with large amounts of other equipment, a rack cooling fan or fans should be part of the rack mount installation.
- Installation of the unit in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.
- Follow the mounting directions described below to prevent uneven mechanical loading, possibly resulting in a hazardous condition.
- Do not overload power supply circuits. Use only supply circuits with adequate overload protection. For power requirements, see Input Power.
- Reliable grounding of rack-mounted equipment must be maintained. Particular attention must be given to supply connections other than direct connections to the branch circuit (e.g., use of power strips).
