2.6
Backplane
The backplane interface provides for status & control communication between the IFMs,
NSM, PSUs and CSM. The CSM communicates its status & control data with HiProvision. User
data communication occurs between IFMs and the CSM. The IFMs are connected in a star
configuration to the CSM resulting in an individual data bus for each IFM. Data transfer is full
duplex. The Backplane Edition and Node Chassis Edition are factory set and cannot be
changed. These editions can be read out via HiProvision.
2.7
PE: Protective Earth
A PE (=Protective Earth) point is provided on the left-hand side panel of the node. The PE
connection ensures that all exposed conductive surfaces have the same electrical potential
as the surface of the earth.
It avoids the risk of an electrical shock if a person touches a device in which an insulation
fault has occurred. An insulation fault (a "short circuit") will cause a very high current flow,
which will trigger an overcurrent protection device (fuse, circuit breaker) and disconnects
the power supply.
