Replacing the VTT Modules and Clock Modules Note Note the position of the VTT module before you remove it from the switch chassis because you must install the new VTT module in the same position. To replace the VTT module, perform these steps: Step 1 Remove the two screws that secure the VTT module. Step 2 Gently lift and remove the VTT module, placing it on an antistatic mat or foam. Step 3 Remove the new VTT from the antistatic bag. Step 4 Hold the module with the connector away from you.
