connectors engage, ease the card into the backplane until fully engaged. Lock top and
bottom with a screwdriver. If resistance is met, remove the card and reinsert. If
difficulty persists contact the Airspan service centre.

mates with the backplane connector correctly. Any attempt to ram the card home or
force the card into he slot may cause damage to the connector. The board extractor
levers mat be used to assist with insertion, when the card is home press the body of the
DIP/LNA to ensure that the connector is fully engaged. If resistance is met remove the
card and reinsert. If difficulty persists contact the Airspan service centre.
