2.2.3.3 Arrangement in the rack
The heat deflection shield R7AI removes the hot air aspired by the fan unit
through the subrack below to the front or rear of the rack. If equipment is
producing heat below the FOX615 subrack, a heat deflection shield R7AI is
also required below the cable tray.
Depending on the evacuation of the heated air, there are two ways of install-
ing the heat deflection shield R7AI (refer to
Figure 2 and Figure 3 :
• Evacuation to the rear:
The heat deflection shield R7AI is installed in such way that the
− cold air flows from the cabinet air inlet into the subrack
− heated air evacuates from the subrack to the rear
Figure 2: Evacuation of heated air to the rear (recommended for 19-
inch installation at the bottom of a cabinet)
• Evacuation to the front :
The heat deflection shield R7AI is installed the opposite way in order to
allow the
− heated air from the subrack below to evacuate through the front door
air outlet.
