System Reset

Resetting the Acme Packet 3900 via the reset pushbutton on the rear of the chassis
performs a cold reboot. This action is the equivalent of disconnecting the power from
the system and then reconnecting it. There is no orderly termination of tasks, and the
system shuts down abruptly. You should only reset the Acme Packet 3900 when it
becomes unstable and no other means of gaining administrative control is possible.
During a system reset, certain files are not closed properly, and they may become
corrupted. If an unclean shutdown is detected, filesystem recovery/repair will be run to
ensure the system returns to a stable state. Filesystem verification also runs every 30
boots as a precautionary measure.
Note:
Always try to reboot first from the ACLI before performing a cold reset. Only
reset the system as a last resort.
•
Insert a rigid paperclip-sized tool into the small hole on the rear of the chassis. The
system immediately resets and begins its initialization and boot sequence.

Power Cycling

Power cycling the Acme Packet 3900 is the process of turning the chassis off and
then on again. When power cycling, it is imperative that you wait at least 10 seconds
between power down and power up to ensure that all components are completely
powered down before restarting the system.

Standby State for HA Nodes

When performing hardware maintenance on the Acme Packet 3900, it is best to
minimize any risk of interrupting network traffic or losing data. If the Acme Packet
3900s are configured as an HA node, you should only work on the node that is in
standby state.
