Concept of system operation Overview
The following hardware and software components are important for the operation of S140:
Service processor (SVP) in the S140 CPU.
This is responsible for the following tasks in the S140 CPU:
–
initialization
– monitoring
– controlling
– hardware diagnosis
The service/console processor (3970-SKP) with the SINIX operating system.
Operation of the S140 system is handled via a local PC, the 3970-SKP service/console
processor. S140 and 3970-SKP communicate with one another in three ways:
– serial line (V.24)
– type-S I/O channel
– internal LAN connection
The following components can be operated via the local 3970-SKP screen and remote
secondary consoles:
– the SINIX system of the 3970-SKP
– the SVP of the S140
– the BS2000 running on the S140
– consoles for up to 15 VM2000 guest systems
– BS2000 applications via 9750 emulation
Automatic Operator (ATOP).
The ATOP is a device which is connected to the 3970-SKP via a serial line. It makes the
following functions possible:
– automatic switching on and off of the S140
– automatic operation of the BS2000 system
The customer can program the ATOP to specify which operating functions should
be executed for which conditions.
Examples:
– automatic shutdown of the system in the case of fan failure.
– automatic command entry in reaction to certain BS2000 console messages.
It is possible to connect a radio-controlled clock or Global Time Server (GTS).
On/off facility makes it possible to switch the S140 on and off from the 3970-SKP.
