Rack Mount Guidelines
This document provides information for mounting the Archive Appliance Express enclosure into an
Electronics Industry Association (EAI 310-D) standard 19” (48.3 cm) rack. The standard 19" rack must
have between 22" and 34" (56 to 142 cm) between front and back mounting columns to provide
sufficient depth for the enclosure. The appliance takes up 2U of rack space. In this document, one rack
unit (1U) equals 1.75" (4.445 cm).
If the unit is installed in a closed or multi-rack assembly, refer to the following guidelines:
• The operation temperature of the rack environment may be greater than the ambient temperature.
Be sure to install the unit in an environment that is compatible with the maximum rated ambient
temperature. See Appendix A Specifications in the User Manual.
• When mounting the equipment in the rack, make sure mechanical installation is level to avoid a
hazardous condition. The rack must be specified to safely support the combined weight of all
equipment.
• When connecting the equipment to the supply circuit, check equipment nameplate ratings to avoid
overloading circuits that may cause damage to over-current protection devices and supply wiring.
• Maintain reliable grounding for rack-mounting equipment. Pay particular attention to supply
connections.
• Allow sufficient air circulation or space between units when installed in a closed or multi-unit rack
assembly to ensure the operating ambient temperature of the rack environment is not greater
than that specified for the library in Appendix A in the User Manual.
• The unit is designed to use a three pronged grounding type plug. Equipment grounding ensures
safe operation. Do not interfere with or remove the grounding means, and verify equipment is
reliably grounded when mounted within a rack.
WARNING
Use safe lifting procedures when installing the appliance in the
rack. The appliance weighs about 33 lbs (15 kg).
