Step 4: Replace the M320 Router Craft Interface

The craft interface is located on the front of the chassis above the FPC card cage.

Action

To remove the craft interface, follow these steps:

NOTE: Removing the front upper fan tray before you remove the craft interface might make it easier to grasp the craft interface as you remove it. For instructions on removing a front fan tray, see the appropriate router hardware guide.

1. Attach an ESD wrist strap to your bare wrist, and connect the wrist strap to one of the ESD points on the chassis.
2. Remove the upper cable guards by loosening the three captive screws on each cable guard.
3. Completely loosen the four captive screws that attach the craft interface to the chassis.
4. Grasp the craft interface by the left and right flanges and carefully pull it straight out of the chassis. (See Figure 79.)
