GFC-8322 and Reference Overview
The GFC-8322 comes standard with every OG3-FR series frame. Its primary function is to distribute
the reference signals to openGear cards installed in the frame. This section provides a general overview
of the GFC-8322.
GFC-8322 Card
Location in Frame
When facing the frame door, the GFC-8322 is located on the left side of the OG3-FR series frame. This
card comes pre-installed in the designated slot immediately to the right of PS1, and is secured with a
metal retaining latch.
Reference Distribution
The GFC-8322 receives the analog reference signals driven to the REF 1 and REF 2 BNCs located on
the rear panel of OG3-FR series frame. The GFC-8322 then distributes both reference signals to each
of the 20 slots in the frame.
Parameter Storage
Frame settings such as the frame IP address, frame name, and the frame serial number are stored on the
GFC-8322 via its Serial EEPROM.
Troubleshooting
During normal operation, the GFC-8322 must never be removed from the OG3-FR series frame. To
ensure this, the metal retaining latch located on the front of the GFC-8322 must be engaged (pushed
down) to prevent accidental removal of the GFC-8322 from its slot.
Verify that the GFC-8322 is properly seated in its slot and the retaining latch is engaged when
troubleshooting any of the following conditions:
• reference signals are unavailable to the cards installed in the frame
• loss of network connection or the network settings for the frame were reset to the default
values
