Legacy Module Support
Installation of 8500 and 8800 modules shipped prior to November 15, 1999 
will cause interruption of the 8900TFN frame communication bus. 
Modules shipped after this date have pins removed in the rear connector to 
provide compatibility. Compatible modules can be identified by the 
absence of connector pins 10 and 50 (see 
). Incompatible legacy 
modules can be returned to Grass Valley for upgrade to the new connector.
Note
If an unmodified legacy module is installed in the frame, the frame commu-
nication bus will be interrupted and all module icons in the frame status 
display will be red. This problem occurs with legacy modules only and does 
not occur with Gecko 8900 Series modules.
