NIU/TCM Removal and Replacement

This section describes how to remove and replace either an NIU or a transcoding Carrier Unit (TCU). Both of these components are fastened to the rear of the Acme Packet 6300/6350 using the same type hardware (i.e., ejection levers and captive thumbscrews).

Prior to removing an NIU/TCU, the platform in which it is installed must be in standby before powering down the chassis and removing the component(s). The following procedure describes how to remove an NIU/TCU.

Note:

Make sure you are properly grounded with an ESD strap before removing the NIU/TCU.
