LaCie 12big rack network Quick Install Guide 1. Introduction 1.1. Safety All plug-in modules and blank plates are part of the fire enclosure and must only be removed when a replacement can be immediately added. The system must not be run without all units in place. In order to comply with applicable safety, emission and thermal requirements no covers should be removed. Permanently unplug the unit if you think that it has become damaged in any way and before you move it. • An enclosure can weigh up to 36kg (79.2lb). Do not try to lift it by yourself. • The unit must only be operated from a power supply input voltage range of 100-240 VAC, 50-60 Hz. • The plug on the power supply cord is used as the main disconnect device. Ensure that the socket outlets are located near the equipment and are easily accessible. • The power connection must always be disconnected prior to removal of a PSU module from the enclosure. • A safe electrical earth connection must be provided to the power cord. Check the grounding of the enclosure before applying power. • Provide a suitable power source with electrical overload protection to meet the requirements laid down in the technical specification. • This equipment is intended to operate with two working PSUs installed in the Power Supply Module. Before removal/ replacement of a PSU disconnect all power for isolation. • A faulty PSU must be replaced with a fully operational one within 24 hours. Caution: If this equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. Introduction page 2 Warning: Do not remove covers from the PSU. Danger of electric shock inside. Return the PSU to your supplier for repair. Caution: The RJ45 sockets on the motherboard/PCI cards are for Ethernet connection only and must not be connected to a telecommunications network. Warning: The enclosure top cover must be secured, when the enclosure is in normal use, by rotating the lock 90° to the 'locked' position. This is to prevent users/operators from accessing the service areas. 1.2. Rack System Precautions The following safety requirements must be considered when the unit is mounted in a rack. • 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 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 (back pressure created by rack doors and obstacles not to exceed 5 pascals (0.5mm water gauge)). • 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 an 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".
