Technicolor - Thomson Electronic Accessory Gecko Frames Signal Processing System ユーザーズマニュアル

Both the 8900 BNC/Video and Balanced Audio frames are equipped with 
IP address storage capability on the rear backplane. When an 8900NET 
module is installed (with version 3.0 software or later), the IP address 
assignments made on the 8900NET module for network configuration are 
stored on the frame. The current network configuration information will 
then stay with the frame if the 8900NET module is moved.

Older version 8900 frames do not have IP address storage capability. IP 
address information is stored only on the 8900NET module. Refer to 

The convection frame and the forced-air frame provide a great deal of flex-
ibility in the type of modules that can be installed. Conventional low power 
analog DAs can be used alongside higher power serial digital modules 
with all modules performing to their full specifications.

For installations that require only low power modules or modules that 
have a combined total dissipation of less than 30 watts, the convection 
frame will provide adequate cooling.

The 30 watt TX-A/-V frame is best used for modules with less than 5.5 watts 
power dissipation. When total power dissipation approaches maximum, 
provide as much space as possible between the modules.

For installations where the modules dissipate greater than 30 watts, a 
forced air frame must be used.

CAUTION Do not leave a fan front cover off of an air-cooled frame for extended periods. 

For reliable operation, the forced-air cover should not be removed for longer 
than five minutes when cooling more that 30 watts.
