The Trusted
cooling within a module rack of a Trusted
trays within a module rack is on a basis of one per module chassis.
The Trusted
mounted vertically at the rear of a 2U high chassis (the illustration above is a
view of the Fan Tray from the rear of the chassis). The chassis containing
the fans incorporates a baffle to prevent air drawn by the fans flowing
through the module chassis immediately above the Fan Tray. Air exhausted
by the fans into the rear of the System cabinet is drawn upwards and out of
the cabinet by roof-mounted fans – see SDS-8271
The Fan Tray is powered from dual 24V dc supplies arranged such that
the fans are supplied in pairs via 250mA anti-surge fuses. The 0V supply is
connected via a terminal block – see block diagram overleaf.
Each fan is capable of moving 69m
speed of 3100 rpm. Protection against overloading and reverse polarity is
provided electronically for each fan.
