Hardware Description & Installation Manual
Frame Cooling Fans
Primary ventilation for the cards installed in the frame is handled by six fans located at the
top rear of the frame, behind the power supplies.
These fans draw air into the frame through a grille and filter in the front door, and exhaust it
through the grate on the rear of the fan assembly.
Power Supply Cooling Fans
Each power supply has two (KXA-PSU-7) or three (KXA-PSU-7-B) fans located on the front of
the supply (behind the extraction handle, in the case of the KXA-PSU-7 power supply).

Card Cooling Fans
Some of the cards in the Kaleido-X system are equipped with on-board fans to ensure
proper cooling of key components. These fans focus the air flow provided by the frame
cooling fans.
Air Filter
Cooling air drawn into the Kaleido-X frame by the ventilating fans passes through a filter
located behind a grille in the front door of the frame. To clean the air filter, see
Cleaning the
Air Filter , on page 32.
IMPORTANT
The Kaleido-X requires a constant flow of cooling air during operation.
DO NOT OPERATE THE UNIT IF THE FRAME COOLING FANS ARE NOT
WORKING.
To replace a defective fan, see
Replacing a Defective Cooling Fan , on page 33.
