We will present some results of two-dimensional particle-in-cell simulations of magnetic reconnection, starting from a recently found collisionless force-free current sheet equilibrium (for the force-free Harris sheet). A number of features will be discussed, such as the time evolution of the electron pressure tensor, magnetic and electric fields, current density, and reconnection rate. These features are compared with those from a Harris sheet plus guide field simulation.
