Replace the NIU in the Acme Packet 4600
chassis.
Replacing Transcoder DSP Modules
Up to twelve transcoder DSP modules that provide transcoding functionality to the
Acme Packet 4600 are installed on the NIU printed circuit board in slots 0 through 11.
Note:
Never remove the heatsink from the transcoder DSP modules.
There are slots for installing the transcoder DSP modules in two locations on the PCB
(two groups - the first of eight slots, and the second of four slots- See Figure 6 - 122).
Transcoder DSP modules should be installed consecutively in numerical order, starting
with slot 0.
