Maintenance
System Shut Down
This chapter explains Acme Packet 6300/6350 hardware maintenance procedures and
provides hardware alarm information. Although several user-replaceable components
of the Acme Packet 6300/6350 are hot-pluggable, some Acme Packet 6300/6350
maintenance procedures require that you shut down the system.
Before you shut down or restart the Acme Packet 6300/6350, ensure that there are
no active calls in progress. Procedures to reroute call and network traffic around the
Acme Packet 6300/6350 are outside the scope of this guide.
You can set the Acme Packet 6300/6350 to reject all incoming calls from your system
with the set-system-state command. When set to offline, this command lets calls in
progress continue uninterrupted, but no new calls are admitted.
After all call processing has stopped, you must halt the operating system before you
power off your Acme Packet 6300/6350. Shutting down the system is appropriate
when you are replacing a physical interface card, storage device, power supply, or are
removing the Acme Packet 6300/6350 from the equipment rack.
