A judicial panel set up by the football governing body imposed a 12-month transfer embargo and a £160,000 fine on the Ibrox club after it was found guilty of five charges in relation to their finances and the appointment of Craig Whyte as chairman.
Supporters marched from Queens Park to Hampden, where they handed in a letter complaining about the outcome of the tribunal.
Former Rangers player Sandy Jardine also made a short speech at Hampden.
An SFA spokesman said: "We are now in receipt of the letter signed on behalf of the Rangers support and are grateful that today's event passed peacefully."
