sections:
• Cabinet and Rack Requirements, page A-1
• Cable Management Guidelines, page A-3

Cabinet and Rack Requirements

This section provides the requirements for the following types of cabinets and racks, assuming an
external ambient air temperature range of 0 to 104oF (0 to 40oC):
• Standard perforated cabinets
• Solid-walled cabinets with a roof fan tray (bottom to top cooling)
• Standard open racks
Note If you are selecting an enclosed cabinet, we recommend one of the thermally validated types, either
standard perforated or solid-walled with a fan tray.
Note Do not use racks that have obstructions (such as power strips), because the obstructions could impair
access to field-replaceable units (FRUs).
This section includes the following topics:
