Prior to removing an NIU (Network Interface Unit), the platform in which it is
installed must be in standby state if it is part of a HA pair before powering down the
chassis and removing the NIU. The following procedure describes how to remove an
NIU.
Make sure you are properly grounded with an ESD strap before
removing the NIU.
To remove an NIU:
1. If the target Acme Packet 4600 is part of a HA pair, ensure that it is in standby
state. For more information, see "Standby State for HA Nodes" on page 6-73.
2. Set the System Power Switch to STBY to power down the chassis. See "DC
Power Supplies (left) and System Power Switch (right)" on page 6-77.
3. Unplug all network and management cables from the NIU you plan to remove
from the Acme Packet 4600.
