The clock generation board has space for four reset switches and/or reset server connections and four red LEDs on it's front panel. Each switch or reset server connection pulls a different reset line low When an 8 by 8 or 16 by 16 switch fabric is being used, two or more of these reset lines are connected together. In order to avoid two or more drivers clashing, some of links 9 to 12 should be removed (see table 1). Currently, the switches have 2 reset server connections: one (the lower one) to driver the left side of the upper and lower backplanes and the other to driver the right side.
