2.11.1 Front Panel Cooling Area
The left one-fourth of the EFP front panel board and the portion of the PDB in this area are cooled by
40 Ч 40 Ч 56 mm dual-rotor fans internal to the PSUs. One PSU is sufficient to cool this portion of the
front panel board area and two PSUs provide cooling redundancy for this area.
PSU fans draw air in through the bezel from the front of the system and from vents in the left front
side of the chassis over this portion of the front panel board and PDB, through and exhausting out the
rear of the PSUs. The left wall of the PCI fan air duct and the PSU guide wall provide an air flow
barrier between the front panel board cooling area and the PCI cooling area
