TX Matrix Plus TXP-CB Description

 

Each TXP-CB works with the Routing Engine to provide the following control and monitoring functions for the TX Matrix Plus router.

TXP-CB Components

Figure 1 shows the TXP-CB.

 TXP-CB

Each TXP-CB consists of the following components (see Figure 1) :

  • 1-GB Ethernet switch used for intermodule communication.

  • PCI bus to the Routing Engines.

  • Switch Processor Mezzanine Board (SPMB).

These components are located on the TXP-CB faceplate:

  • Three Routing Engine ports—ETHERNET, CONSOLE, and AUX—located below the Routing Engine, for connecting the Routing Engine to external management devices.

  • Two port LEDs—ETHERNET and ACT—located next to the ETHERNET port indicate the port status and speed.

  • Three status LEDs—MASTER, FAIL, and OK— indicate the status of the TXP-CB.

  • Online/offline button, located below the status LEDs.

Routing Engine Ports on the TXP-CB

Each TXP-CB has a set of ports that you use to connect the Routing Engines to external management devices (see Figure 1). From these management devices, you can use the CLI to configure and manage the TX Matrix Plus router.

The management ports on each TXP-CB connect to the Routing Engine installed into that TXP-CB. Each TXP-CB includes the following ports:

  • ETHERNET—10/100-Mbps/1-Gbps Ethernet port for connecting to a management network. Connects the Routing Engine through an Ethernet connection to a management LAN (or any other device that plugs into an Ethernet connection) for management of the routing matrix. The port uses an autosensing RJ-45 connector to support 10-Mbps, 100-Mbps, or 1-Gbps connections. Two small LEDs on the left edge of the port indicate the connection in use.

  • CONSOLE—One asynchronous serial port for connecting to a console. Connects the Routing Engine to a system console through an RS-232 (EIA-232) serial cable.

  • AUX— One asynchronous serial port for connecting to a modem or other auxiliary device. Connects the Routing Engine to a laptop, modem, or other auxiliary device through an RS-232 (EIA-232) serial cable.

Note

If a TX Matrix Plus router contains two host subsystems, connect both TXP-CBs to your external management network.
