6 Operation and Maintenance
This chapter describes maintaining the system and configuration data as well as up-
dating the system software. Replacing cards, modules and terminals are also de-
scribed. The display and control panel of the communication server as well as oper-
ations supervision using the event message concept, the operating state display, and
the error display are also topics covered in this chapter.
6. 1 Data Maintenance
6. 1. 1 What data is stored where
The communication server’s data storage system consists of different elements:
• In the Flash components are stored the system software, the boot software and the
configuration data. 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.
• The EIM card (Equipment Identification Module) contains the system-specific data
(system ID, system type, sales channel, licence code, generation, DECT identifica-
tion numbers, IP address of the configuration server). The contents of the memory
are retained even when there is no power supply.
• The data of applications on the applications server (if a CPU2-S applications card is
fitted) is stored on a hard disk.
