Caution
: Power supply cords shall have conductors with a cross-
sectional area not less than 4mm

. This cross-sectional area
corresponds to a minimum 10AWG wire.
Cooling System
Cooling is provided by the two Advanced Cooling Modules (ACMs)
located at the rear of the enclosure. Each of the ACM units contain two
variable speed fans. The enclosure requires four fans for normal
operation, but will operate correctly with one fan failed (redundancy is
lost if one fan is failed in either ACM), however, it is recommended
that the failed fan be replaced as soon as possible. The ACM units can
be hot swapped. The LS Module monitors and controls the speed of
each fan. The speed is set depending on the ambient temperature and
failed status. The fans are set to full speed if one fan is failed. The
following table shows how the fan speed relates to temperature
change.
Note
: All fans in an enclosure are set to the same speed.
