Install Power Supplies; Install Fan Trays - Aruba 8360 Series Installation And Getting Started Manual

Cooling air flow in Aruba 8360 switches is Port-to-Power or Power-to-Port, depending on which power
supply and fan tray options are installed. To reverse the cooling air flow direction in an 8360 switch, you
must replace the existing power supplies and fan trays with power supplies and fan trays having the
opposite air flow direction. All fan trays and power supplies installed in an 8360 switch must have the same
air flow direction. See Fan Trays
