2 Chassis Installation
32 M9506A-BC1 5-Slot AXIe Chassis with Integrated Controller User Guide
Ventilation
The chassis is designed to dissipate up to 250 W per instrument
slot. Depending on load, the chassis and power supply fans may exhaust
significant heat. Whether used on the benchtop or rack-mounted, operate in a
well-ventilated environment and allow at least 2” (5 cm) clearance around both
sides of the chassis.
Airflow through the chassis is from right to left; that is fresh air is drawn in from the
right side and exhausted from the left side.
When installing the instrument(s) into a cabinet consideration shall be given to the
convection flow into and out of the cabinet. Consideration shall also be given to
the individual instruments to avoid having the heated discharge of one instrument,
now becoming the cooling intake air for another instrument.
Another area of concern is verification that the maximum ambient operating
temperature of the instrument(s) is not exceeded by cabinet installation. Keysight
recommends forced air convection whenever an instrument is installed in a cabinet
and further recommends that the maximum operating temperature of the cabinet
be reduced 10 °C from the lowest, of the maximum operating temperature of a
single instrument.
If there are any concerns or special requirements a Keysight Field Engineer should
be consulted to assure instrument temperature compliance and performance.
CAUTION
Do not block the vent holes on the chassis. This may cause
overheating and damage to components. Leave a gap of at least
2” (50mm) around all vent holes and fan exhaust areas.
