LaCie 12big Rack Network User Manual Foreword page 5 Safety Guidelines Safe Handling CAUTION: If this equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. ✦✦ All plug-in modules and blanking 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 and all bays must be fitted with plug-in modules. Permanently unplug the unit if you think that it has become damaged in any way and before you move it. CAUTION: A fully assembled LaCie 12big Rack Network enclosure can weigh up to 30kg (66lb), 22kg (48.4lb) without drives installed. Do not try to lift it by yourself. Do not lift the enclosure by the handles on the power supplies, as they are not designed to support that weight. CAUTION: The removal of the enclosure top cover or the power supply mounting cage must only be performed by a service person. Potential hazards include: rotating fans and hot surfaces. 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 service areas). Safety ✦✦ The LaCie 12big Rack Network 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. ✦✦ This equipment is intended to operate with two working Power Supply Units (PSUs) housed in a Power Supply Mounting Cage. Before removal/replacement of a PSU disconnect all supply power for complete isolation. ✦✦ A faulty PSU must be replaced with a fully operational PSU within 24 hours. Please refer to section 6.3. Environment. ✦✦ A safe electrical earth connection must be provided to the power cord. Check the grounding of the enclosure before applying power. CAUTION: Bifurcated power cords MUST NOT be used with the LaCie 12big Rack Network enclosure, this system does not support their use. ✦✦ Provide a suitable power source with electrical overload protection to meet the requirements laid down in the technical specification. ✦✦ Hot surfaces (heatsinks) are exposed when the enclosure top cover is removed. Disconnect power and allow to cool before removal/replacement of the SAS Expander PCB. CAUTION: Do not remove covers from the PSU. Danger of electric shock inside. Return the PSU to your supplier for repair. BBU Battery Safety (RAID option) Please refer to section 5.9. Replacing the Battery Backup Unit. CAUTION: There is a danger of explosion if the battery is replaced by an incorrect type. Dispose of used batteries in accordance with the manufacturer's instructions and National regulations. Equipment Handling Precautions CAUTION: Operation of the Enclosure with ANY drive carrier modules missing will disrupt the airflow and the drives will not receive sufficient cooling. It is ESSENTIAL that all apertures are filled before operating the unit. Dummy drive carrier modules must be fitted to unused drive bays. CAUTION: The RJ45 sockets on the Motherboard/PCI cards are for Ethernet connection only and must not be connected to a telecommunications network. CAUTION: Boot drives are fragile and must be handled with care during removal/replacement.
