Hardware Installations and Upgrades number of units installed in the rack. Consideration of the units' nameplate rating should be used when addressing these concerns. • The electrical distribution system must provide a reliable earth for each unit and the rack. • Each storage system has an earth leakage current of 0.75 mA. 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 and IEC 6095-10. Rack Mount Rail Kit A set of mounting rails is available for use in 19-in rack cabinets. These rails have been designed and tested to handle the maximum enclosure weight and to ensure that multiple enclosures may be installed without loss of space within the rack. Use of other mounting hardware may cause some loss of rack space. Assembling the Rail Kit Please refer to the Rail Kit Install Guide: Intel® Storage System SSR212MA/Intel® Storage System SSR212CC supplied with the rack mounting rail kit for assembly details.
