II.4. DS200L
Six-rack cabinets are used in the DS200L systems. 2 of TW200 towers can be installed into
six-rack cabinet. The rack structure of TW200 is similar to the usual DS200 rack structure.
The main differences are that; CC card is used instead of CPU200 and Utility 4E1 card can
be mounted on to the UTIL200 card. Furthermore, redundant CC card can not be installed. 1
TW200 tower consists of 1 main rack and maximum 2 auxiliary racks. TW200 racks consist
of the parts below:
•
RACK200 basic metal rack structure
•
SPS200 AC/DC Power Supply (for small capacities)
•
SPS248 DC/DC Power Supply
•
BPL200-AUX Backplane (only for auxiliary rack)
•
BPL200-MAIN Backplane (only for main rack)
•
BPL200-SPS Backplane or BPL200-SPSX Backplane
•
CC communication unit, the CPUKON Card and the DS200 CPU-FC CPU Flat Cable
•
The UTIL200 Utility Card and the Utility 4E1 card
•
The EX200 Expansion Modules (at most 14 modules)
II.4.A. RACK STRUCTURE OF TW200 (TOWER 200)
A TW200 tower consists of maximum 3 TW200 racks, namely a main rack and two auxiliary
racks. (In fact, only a single main rack is enough to establish a tower.) The rack structure of
TW200 is same as the DS200 rack structure (see section II.1.B). The UTIL200, CPUKON
and other cards that are used in DS200 racks are also used in TW200 racks. However, since
the PCU Block functions as the main processor in the DS200L system, no CPU200 card is
available. The CC200 card is employed instead of the CPU200 card. Necessary information
on the CC200 and UTILITY 4E1 cards are supplied below.
II.4.B. THE SIX-RACK CABINET
Six rack slots are available in this cabinet, which are required to install a system with at most
six racks. Hence, it is used for six-rack systems. Two TW200 towers of the DS200L systems
can be placed in a 6-rack cabinet.
Details regarding the elements of a 6-rack cabinet have been illustrated in the figure below.
