Installation

Datacryptor Ethernet User Manual

Airflow

Make sure that there is sufficient flow of air around the Datacryptor so that safe operation is not compromised. Maintain a clearance of at least 3 inches (7.62 cm) at the sides of the Datacryptor to ensure adequate air intake and exhaust. If installing in an enclosed rack, make sure the rack has adequate ventilation or an exhaust fan. An enclosed rack with a ventilation system that is too powerful can prevent proper cooling by creating negative air pressure around the Datacryptor.

Mechanical Loading

Keep the center of gravity in the rack as low as possible. This ensures that the weight of the Datacryptor will not make the rack unstable. Make sure that the rack is secured and use the proper mounting hardware to secure the Datacryptor to the rack.

Circuit Loading

Consider the connection of the Datacryptor to the supply circuit and the effect that overloading of circuits might have on over current protection and supply wiring. Consult the voltage and amperage ratings on the UL label affixed to the unit’s rear panel when addressing this concern. As the 1 Gig and 10 Gig Ethernet units are fitted with two hot swappable power supply units, consideration could be given to these types of Datacryptors using a different supply phase for each of the power supply units.

Disconnection

Power disconnection is achieved by removal of the plugs from the mains outlet sockets. Ensure that the socket-outlets are close to the unit, and can be easily identified and accessed.

Grounding

Maintain reliable grounding of a rack-mounted Datacryptor. Pay particular attention to supply connections other than direct connections to the branch circuit, such as the use of power strips.

Maintenance

Allow at least 19 inches (48.3 cm) of clearance at the front of the rack for maintenance. Use a cable-management system to help keep cables organized, out of the way, and free from kinks or bends that degrade cable performance.

Connect the Cables

Before beginning, make sure the necessary cables are available. See the Cabling Requirements section below for more information.
