Kaleido-X (7RU)
Hardware Description & Installation Manual
To monitor airflow efficiency, the Kaleido-X offers on-board probing that monitors the
temperature in strategic areas. Use the table, below, to determine whether measured
values exceed recommended values.
The vast majority of installations meet these requirements. In the case of multiviewers
installed in an environment where cards are prone to exceed the recommended
temperature, Grass Valley recommends replacing the standard frame cooling fan assembly
with a special fan tray that will help improve the airflow within the equipment rack or
cabinet.
The Adapted Fan Tray (part number KXA-FAN-TRAY-1) is compatible with both
Kaleido-X (7RU) frame models (part numbers KXA-FR7, and KXA-FR7-B). It ensures a vertical
airflow (as opposed to the standard frame cooling fan assembly whose ventilation exhaust
is directed horizontally), and can be mounted in four different configurations:
• Fan assembly on the left, facing up, attached to top side of tray (default configuration)
• Fan assembly on the left, facing down, attached to underside of tray
• Fan assembly on the right, facing down, attached to underside of tray
• Fan assembly on the right, facing up, attached to top side of tray
If measured values exceed recommended values, make the necessary corrections to your
installation (please contact Grass Valley Technical Support for the recommended practice).
Power Supplies
The Kaleido-X is powered by dual redundant power supplies. These are installed at the top
of the frame above the cards. The supplies are installed and removed from the front of the
frame and are hot-swappable, so that a defective supply may be replaced without
removing the Kaleido-X from service.
Monitored values via XAdmin Temperature should not exceed
Input cards 75 ºC (167 ºF)
Output cards 83 ºC (181 ºF)
Keep in mind that these values are measured at the chip level and should be
interpreted as relative indicators of the cards’ internal temperature and of the
system’s overall ability to evacuate excess heat, in the context of your
specific system configuration.
IMPORTANT
There are two different models of 7RU frames, and two models of power
supply units. They are not interchangeable.
• If you have a frame model KXA-FR7-B then you need the KXA-PSU-7-B
power supply and you must ensure the supply is grounded before
connecting your system.
• If you have a frame model KXA-FR7 then you need the KXA-PSU-7 power
supply.
