return to service. This causes a soft-reboot rather than a system power cycle.
Caution Make sure you are properly grounded with an ESD strap
before removing the NIU.
NIU Removal
To remove an NIU:
1. Unplug all network and management cables from the NIU you plan to
remove from the Acme Packet 6100.
Note: This will cause a link loss on all connections.
2. Using a #2 Phillips screwdriver, unscrew the two captive thumbscrews
located on each side of the NIU. The screws are spring-loaded and will
push forward, but they will not fall out of the NIU.

3. Pivot the two ejection levers outward at the same time, pulling the card out
of its connection to the motherboard and away from the system chassis.
This action disengages the NIU from the system, severing all electrical
contact to the processing unit.
