TX Matrix Plus Midplane Description

The midplane is located in the center of the chassis and forms the rear of the TXP-F2 SIB card cage (see Figure 1). The TXP-F2S SIBs, TXP-CIPS, TXP-CBs, and Routing Engines install into the midplane from the front of the chassis, and the TXP-F13 SIBs install into the midplane from the rear of the chassis. The power supplies and cooling system components also connect to the midplane.

The midplane performs the following major functions:

• Power distribution—The TX Matrix power supplies are connected to the midplane, which distributes power to all the TX Matrix components.
• Signal connectivity—The midplane provides signal connectivity between all TX Matrix components for monitoring and controlling the system.
• Redundancy connectivity—The midplane provides redundant paths for all critical connections.
