    Technical white paper Page 10 • Avoid tight-bend radii. Cables should never be bent tight enough to cause a crease in the sheathing. Fiber cables must not violate their minimum bend radius without exception. • When securing cables inside the rack, the bundle should be dressed in such a way as to avoid interference with installed components or rack side panels or rails.
  • Page 12: Installation And Maintenance Precautions

    Moving racks with casters Racks with casters should be moved with care. Sudden stops, excessive force, and uneven surfaces may cause the product to overturn. HPE G2 Racks have casters that are fixed in the front and swivel in the rear due to stability and safety concerns. Therefore, it is both recommended and easier to move the rack with the back as the leading edge.

  • Page 16: Equipment Clearance And Floor Loading

    Technical white paper Page 15 Equipment clearance and floor loading A clearance of 1219mm (48 in) in front of a configured rack and 762mm (30 in) to the rear of a configured rack is recommended. All buildings and raised computer room floors are engineered to provide a specific floor loading. Warning When configuring a solution, make sure that the floor loading specifications are followed.
  • Page 17: Rack And Accessory Footprints

    Technical white paper Page 16 Rack and accessory footprints When accessories, such as stabilizing kits are added to a particular rack, the footprint of the rack will extend into rack rear row and infringe upon necessary clearances. See figure 7 and 8. Figure 7.
  • Page 18: Front Door Clearance

    There are slight differences between the opening allowances of the Infrastructure Racks and HPE G2 Advanced Series Racks due to the different geometries and construction of the doors.
  • Page 19: Qualified Shipping

    Qualified shipping All HPE G2 Racks can be shipped in two standard shipping configurations, depending on the shipping environment and configuration. Shipment of empty racks is typically done on a standard wooden pallet. Racks for shipping configured loads are on a shock pallet.
