TX Matrix Plus TXP-CB Description

TXP-CB Components

Figure 1 shows the TXP-CB.

Figure 1: TXP-CB

• 1-GB Ethernet switch used for intermodule communication.
• PCI bus to the Routing Engines.
• Switch Processor Mezzanine Board (SPMB).

• Three Routing Engine ports—ETHERNET, CONSOLE, and AUXILIARY—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 TX Matrix Plus TXP-CIP). 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 iinstalled 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.
• AUXILIARY— 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.
