TX Matrix Plus Router SIBs
In the TX Matrix Plus router, one data switching plane consists of one or two TXP-F13
SIBs connected internally through the midplane to four TXP-F2S SIBs. For the TXP-4
configuration, there are a total of five data switching planes in the routing matrix. One of
the five data switching planes acts as a backup spare to the remaining data switching
planes. If faults are detected in an active data switching plane, the plane is taken offline,
and the backup spare plane is brought online. When a failed component is replaced and
brought online, the data switching plane in which it resides becomes the new backup
spare plane.
