Replacing a T320 Craft Interface

 

The craft interface is hot-insertable and hot-removable. When you install the craft interface, allow several minutes for the display to reflect the current state of the router. Before you remove the craft interface, remove the front upper fan tray. For instructions on removing a front fan tray, see Removing a T320 Front Fan Tray.

The craft interface is located on the front of the chassis above the FPC card cage. The craft interface weighs approximately 2 lb (0.9 kg).

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 Removing a T320 Front Fan Tray.

To remove the craft interface (see Figure 1):

  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. Completely loosen the screws at the four corners of the craft interface.
  3. Insert the blade of a flat-blade screwdriver into the slot on one side of the craft interface, then gently pry that side out from the chassis.
  4. Repeat Step 3 for the other side of the craft interface.
  5. Grasp the craft interface by the top and bottom edges and carefully pull it straight out of the chassis.
