The allegations include two alleged sexual assaults that she said occurred in 2001.
Dixon seeks unspecified compensatory and punitive damages in her lawsuit.
The window closes this month.
Dixon first accused Reid of misconduct in December 2017.
At that time, Reid spoke to The New York Times.
Im proud of my track record promoting, supporting, and uplifting women at every company Ive ever run.
That notwithstanding, if I have ever said anything capable of being misinterpreted, I apologize unreservedly.
In her legal filing today, Dixon claimed Reid began harassing her shortly after arriving at Arista in 2000.
The second alleged assault occurred several months later during a ride home from an event in New York.
Dixon claimed Reid groped, kissed, and penetrated her without consent.
Dixon said her career stalled after that, as Reid became hostile.
She said her budgets were slashed and her artists rejected when she did not submit.
She left the industry to 2002 to attend Harvard Business School.
