CHAPTER 6 OPERATION AND MAINTENANCE
Operation and Maintenance
This chapter describes maintaining the system and configuration data as well as updating the system soft-
ware. Replacing cards, modules and terminals are also described. The display and control panel of the
communication server as well as operations supervision using the event message concept, the operating
state display, and the error display are also topics covered in this chapter.
Data Maintenance
What data is stored where
The communication server’s data storage system consists of different elements:
• In the Flash components the following data are stored: the system software, the emergency system
software, the boot software for the SMB Controller, the MiVoice Office 400 application software
and its configuration data and maybe other application software. Furthermore system-specific
MiVoice Office 400 data (system ID, system type, sales channel, generation, DECT identification
numbers, IP address of the configuration server) are stored there. There is no EIM (Equipment Iden-
tification Module) available. The contents of the memory are retained even when there is no power
supply.
• In the RAM components (main memory) are stored volatile data that cannot be saved. It is available
only when the system is in operation.

System software
When we talk about the system software we have to distinguish between the SMB Controller system soft-
ware (based on Linux) and the MiVoice Office 400 application software, running in this Linux environment.
Both software packages are stored in compressed form in the Flash memory.
