PNC State of Health Indexes
The Inter-PN and Inter-SN Indexes form the state of health vector, which is used
to track and compare the states of health of both PNCs. The fields making up the
indexes are two digit numbers separated by periods (.), with each field
representing a different class of faults. The fault class fields are arranged in order
of decreasing importance from left to right. In other words, each field in the index
supersedes the following fields in determining which PNC is healthiest. A fault
class drives an interchange only when all of the higher priority fault classes are
equal. A zero entry indicates no faults in that class. Increasing numbers indicate
increasingly higher numbers of faults present in that class.
The Inter-PN Index contains five fields (XX.XX.XX.XX.XX), and the Inter-SN Index
has two (XX.XX). The Inter-PN Index reports faults in connectivity between port
networks and supersedes the Inter-SN Index, which reports faults in connectivity
between switch nodes. (The Inter-SN Index is only meaningful for systems with a
center stage switch having 2 switch nodes, each of which is duplicated).
The meaning of each fault class field is given in the following table. A zero entry
indicates that there are no such faults reported. Higher numbers indicate
increasing number of faults. All zeros indicates perfect state of health. Unless the
PNCs are locked, the active PNC’s state of health should always be equal to or
better than the standby’s. (Otherwise, the system would perform a spontaneous
interchange.)
