V.3.A.3. REDUNDANCY
It is possible to backup the PCU200 block upon wish, with another PC that is a one-to-one
copy of it. The redundant and functional PCU200 blocks are in connection with each other
through ethernet ports and in case of any malfunction that occurs in the functional PCU200
block, the redundant PCU200 directly becomes functional.
V.3.B. THE CC MODULE
The CC module, instead of the CPU module, is used in the DS200L system.
The function of the CC200 module is to provide communication between the PCU200 block
and the racks. The CC200 card and the CPUKON card work in coordination again.
CC card has:
■ 1 Ethernet port
■ 16 MB Flash Memory
■ 64 MB RAM
■ Linux operating system
NOTE: No redundant CC200 is used in the TW200 towers. Since the PCU200 block fulfills
the tasks of CPU200 card, redundancy of the PCU200 block is available in the DS200L
exchange.
