Kaleido-X (7RU)
Installation & Service Manual
Monitoring the Temperature of the Kaleido-X
For optimal performance, it is strongly recommended that you operate the Kaleido-X in an
environment with an ambient temperature lower than 20 ºC (68 ºF).
There are two factors that could influence airflow inside the frame:
• altitude
• airflow obstruction at the rear of the unit
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 (contact Grass Valley Technical Support for the recommended practice).
IMPORTANT
When measuring the ambient room temperature, take your readings
from directly in front of the Kaleido-X frame.
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 shed excess heat, in the context of your specific
system configuration.
