Guidelines for DC-powered equipment
A DC-powered installation must meet these requirements:
• Use a 15 amp external branch circuit protection device to install the unit.
• For permanently connected equipment, incorporate a readily accessible disconnect in the fixed wiring.
• Use only copper conductors.
• Cabling for the system must be grounded on both sides.
• Use one power feed for each individual power supply.
Caution: Install DC-powered equipment only in restricted access areas, such as dedicated equipment
rooms, equipment closets, or similar locations.
Avertissement : Installer le matérial alimenté par courant continu uniquement dans des zones à accès
reglementé, telles que des salles de matériel, des armoires de materiel ou tout emplacement similaire.
Platform airflow diagram
When you install the platform into a rack, it is important to understand the unit's airflow direction so that
you can ensure proper cooling.
The platform employs a negative pressure fan system, which draws cold air in from the front of the
chassis.
