The Summa processing core is a
4U 19’ rack mount unit designed
for installation into standard 19’
equipment bays.
Airflow
The core is cooled by fan assisted
convection. Air is drawn in through
inlets at the base/front and exits via 3
fans mounted to the rear of the core.
The speed of each fan is monitored and
System Status error reports are generated
for any failures. Air inlets and fans should
be left clear and unobstructed to ensure
air can flow through the card frame. No
clearance is required above or below the
core for cooling.
Support
The weight at the rear of the core should
be adequately supported to prevent
stress on the front racking angles. This is
particularly important when the units are
mounted in mobile installations. Calrec
will not accept liability for damage caused
by insufficient support.
Calrec supply adjustable rear support rails
with each Summa core that can be fitted
during installation if required. The support
rails can be fitted in different positions
depending on the depth of the bay being
used. Rear racking angles slide over the
support rails so the depth can be adjusted
to match the position of the rear core
fixings in the equipment bay.
