LaCie 12big Rack Network User Manual Installation page 19 2.3.4. Special Tools and Equipment There are no special tools required but in order to complete the assembly of some configurations you may need the following: ✦✦ Flat blade screwdriver (not supplied) ✦✦ Torx driver (for drive module locks) 2.3.5. Rack Installation Pre-Requisites The LaCie 12big Rack Network Enclosure is designed for installation into an industry standard 19 inch cabinet capable of holding the unit. ✦✦ Minimum depth 707mm (27.83 inches) from rack posts to maximum extremity of enclosure (excludes rear cabling). ✦✦ Weight: up to 30kg, dependent upon configuration, per enclosure. ✦✦ A minimum gap of 25mm (1inch) clearance between the rack cover and front of drawer; and 50mm (2 inches) rear clearance between rear of drawer and rear of rack is recommended in order to maintain the correct air flow around the enclosure. ✦✦ The rack should present a maximum back pressure of 5 pascals (0.5mm water gauge). CAUTION: Operation of the enclosure system with ANY 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 Carriers and/or Blanking Plates are available for this purpose. Fig. 13 - Rack Mounting Rail Kit 2.4. Rack Mounting Rail Kit A set of rack mounting rails is available for use in 19 inch 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. Please contact your supplier to ensure suitable mount rails are available for the rack you are using. Important Please refer to section Rack System Safety Precautions before you begin the assembly procedure. 2.4.1. Mounting Rail Kit Installation Please refer to the detail drawings supplied with the Rack Mounting Rail Kit for assembly details (Xyratex P/N 82864-01). This drawing is also shown in 8. Rack Kit Reference Drawing.
