Installation
27
• The rack design should incorporate stabilizing features suitable to prevent the rack from tipping or
being pushed over during installation or in normal use.
• When loading a rack with the units, fill the rack from the bottom up and empty from the top down.
• The rack should have a safe electrical distribution system. It must provide over-current protection
for the unit and must not be overloaded by the total number of units installed in the rack.
Consideration of the electrical power consumption rating shown on the unit’s nameplate should be
used when addressing these concerns.
• The electrical distribution system must provide a reliable earth for each unit in the rack.
• Each power supply in each unit has an earth leakage current of 0.75mA. The design of the electrical
distribution system must take into consideration the total earth leakage current from all the power
supplies in all the units. The rack will require labelling with “HIGH LEAKAGE CURRENT. Earth
connection essential before connecting supply”.
• The rack, when configured with the units, must meet the safety requirements of UL 60950-1:2005
(2nd edition) and IEC 60950-1 2nd edition.
3.2.4 Rack Installation Pre-Requisites
The SteelStore appliance is designed for installation into an industry standard 19-inch rack cabinet
subject to the following requirements:
• There must be a minimum depth of 707 mm (27.83 inches) from rack posts to maximum extremity
of appliance (excluding rear cabling).
• The rack must be able to support appliances weighing up to 32 kg (71 lb).
• There must be a minimum gap of 25 mm (1 inch) between the rack cover and front of the appliance.
• There must be a minimum gap of 50 mm (2 inches) between the rear of the appliance and the rear
of the rack to maintain the correct air flow around the appliance.
• Use in a fully enclosed rack installation is not recommended.
• The rack design should take into consideration the maximum operating ambient temperature for the
unit, which is 35°C.
• The system must be operated with low pressure rear exhaust installation. The back pressure created
by rack doors and obstacles must not exceed 5 pascals (0.5mm water gauge).
Warning Operation of the appliance with ANY modules missing will disrupt the airflow and the system will
not receive sufficient cooling. It is ESSENTIAL that all apertures are filled before operating the
unit. Dummy drive carriers and/or blanking plates are available for this purpose.
