Introduction
This chapter explains Acme Packet 4500 hardware maintenance procedures. This
chapter also provides hardware alarm information.
System Shut Down
Although several user-replaceable components of the Acme Packet 4500 are hot-
swappable, some Acme Packet 4500 maintenance procedures require that you shut
down the system.
Before you shut down or restart the Acme Packet 4500, ensure that there are no
active calls in progress. Procedures to reroute call and network traffic around the
Acme Packet 4500 are outside the scope of this guide.
You can set the Acme Packet 4500 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 can power off your Acme Packet 4500.
Shutting down the system is appropriate when you are replacing a physical interface
card, power supply, or are removing the Acme Packet 4500 from the equipment rack.
