5 Maintenance Introduction
System Shut Down
This chapter explains Net-Net 6300 hardware maintenance procedures. This chapter
also provides hardware alarm information. Although several user-replaceable
components of the Net-Net 6300 are hot-plugable, some Net-Net 6300
maintenance procedures require that you shut down the system.
Before you shut down or restart the Net-Net 6300 ensure that there are no active
calls in progress. Procedures to reroute call and network traffic around the Net-Net
6300 are outside the scope of this guide.
You can set the Net-Net 6300 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 Net-Net 6300. Shutting down the system is appropriate when you
are replacing a physical interface card,Storage Device, power supply, or are
removing the Net-Net 6300 from the equipment rack.
