Removing the M120 Craft Interface

The craft interface is located on the front of the chassis above the FPC card cage. The craft interface weighs approximately 1.6 lb (0.73 kg).

To remove the craft interface (see Figure 1):

Note: Removing the front upper fan tray before you remove the craft interface makes it easier to grasp the craft interface as you remove it. For instructions on removing a front fan tray, see Replacing an M120 Fan Tray.

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
2. With a 3/8-inch nut driver or pliers, loosen and remove the two nuts that secure the craft interface to the chassis. Also remove the two washers located behind the nuts.
3. Grasp the craft interface by the left and right flanges and carefully pull it straight out of the chassis.
