5 VDC Additional Power Supply (H51X)
The 5 VDC power supply can be extended by a H51X additional power supply consisting of the
B 9361 set and at least an F 7126 power supply unit.

System Bus
The HIQuad X system is based on the redundant system buses A and B. Each system bus is
controlled and monitored by one processor module located in the base rack. For redundant
operation, the system must be operated with two processor modules. In redundant operation,
communication runs on both system buses simultaneously. If only one processor module is
inserted in the base rack, the system runs in mono operation with only one system bus.
Redundant operation ensures that, if one processor module fails, communication is maintained
by the redundant processor module via one system bus. To ensure redundant operation again,
the defective processor module must be replaced immediately.
It is not allowed to interconnect the system buses of several HIQuad X systems!
No active elements such as switches may be connected to the system bus.
NOTICE
System malfunction possible!
Using system bus connectors XD1...XD4 on the back of the backplane PCB as normal
Ethernet connections may cause the system to malfunction.
Only use the system bus connectors XD1...XD4 to connect to the I/O processing
modules (F-IOP 01).
Do not interconnect or cross system bus A and system bus B.
The system buses connect the I/O level to the processor modules via the I/O processing
modules (F-IOP 01). To do so, the RJ-45 interfaces on the rear side of the base racks must be
connected to the I/O processing modules, see Chapter 3.2. The maximum length of the patch
cable between two system bus subscribers is 50 m. The cable diameter must be selected in
relation to the cable length.
