TX Matrix Connector Interface Panel (TX-CIP) Description


TX-CIP Description

The TX Matrix router contains one or two TX-CIPs—one for each Routing Engine—that install vertically into the front left of the chassis in the slots labeled CIP0 and CIP1 (see Figure 1). The front electrostatic discharge point is located near the bottom of the TX-CIP.

The TX-CIP is hot-removable and hot-insertable.

Control Plane Ports

Each TX-CIP contains four RJ-45 ports labeled LCC 0 through LCC 3. These ports provide T640 router control by connecting to Control Boards in up to four T640 routers through UTP Category 5 Ethernet cables.

  • The TX-CIP in the CIP0 slot connects to CB0 in each T640 router.

  • The TX-CIP in the CIP1 slot connects to CB0 in each T640 router.

See Control Plane Connections Between the TX Matrix Router and T640 Router.


The RJ-45 ports labeled LCC 4 through LCC 7 on a TX-CIP are reserved for future use.

Routing Engine Ports

Each TX-CIP has three ports for connecting the corresponding host subsystem to external management devices (see Figure 1). From these management devices, you can use the CLI to configure the TX Matrix router. The ports on TX-CIP in slot CIP0 connect to the Routing Engine in slot RE0, and the ports on the TX-CIP in slotCIP1 connect to the Routing Engine in slot RE1.

  • One 10/100-Mbps 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 out-of-band management. The port uses an autosensing RJ-45 connector to support both 10- and 100-Mbps connections.


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

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

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

Alarm Relay Contacts

Each TX-CIP has two alarm relay contacts—labeled RED ALARM and YELLOW ALARM—for connecting the TX Matrix router to external alarm devices (see Figure 1). Whenever a system condition triggers either the red or yellow alarm on the craft interface, the alarm relay contacts are also activated. The alarm relay contacts are located below the Routing Engine ports.
