− To engage the unit with the backplane connectors, press carefully and
simultaneously the levers (11) and (12) inwards (B) while at the same
time pressing (C) the unit via the unit front into the subrack.
− The lever movement and insertion force will engage the connectors of
the unit to the backplane connectors.
