ST950 ELV CPU Card
Variants
There are two variants of the ST950 CPU card which differ only in the amount of
RAM available on the EFC module.
•
667/1/46010/001 – 64M RAM
•
667/1/46010/101 – 128M RAM
The 101 variant is compatible with all applications and is required when connecting
to Stratos (see section 7.4.6). See 667/SU/46000/000 for full compatibility
information.
General
The CPU Card controls the system. It holds the controller configuration and
performs the function of configuration, control and management. The primary
external data interfaces are shown in Figure 19 and detailed in Table 5.
One serial phase bus and two GSPI bus connectors are available on 3 separate
RJ45 sockets on the rear of the CPU Card. The forth RJ45 socket is reserved for a
future GSPI Manual Panel is blanked off and should not be used.
The RJ45 socket marked "LSLS" on the CPU Card must be connected to the LSLS
cards in most cases. For controllers where the LSLS cards are located in the 19"
rack along with the CPU Card, the front serial phase bus connector is used with a
10way IDC cable link to the 1st LSLS.
The two GSPI interface RJ45 sockets are identical and both marked "SIO". One of
these is connected to the IO cards and the other, to Intelligent Detector Backplanes.
It is not important which connector is used for the IO and which is used for the
Intelligent Detector Backplanes.
