 **Laser Current (SMA)**
+<WRAP center round important 60%>
+Never connect or disconnect the D2-100 Laser to a laser controller that is energized.  Always power down the laser controller completely before making connections to this laser.
+Always make sure to make a snug connection between the D2-100 and the current-carrying SMA cable, and between the cable and the laser controller.
+</WRAP>
 Current is provided to the DBR chip through an SMA connector.  The central conductor of the SMA connects to the laser anode, and the shield connects to the laser cathode.  //This is a direct, unprotected connection to the DBR chip, so care must be taken to avoid ESD damage.//
