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 TX-CIPs are referred to as TX-CIP-0 and TX-CIP-1. The front electrostatic discharge point is located near the bottom of the TX-CIP.
The TX-CIP is hot-removable and hot-insertable.

Each TX-CIP contains four RJ-45 ports labeled LCC0 through LCC3. These ports provide T640 router control by connecting to T-CBs in up to four T640 routers through UTP Category 5 Ethernet cables. TX-CIP-0 and TX-CIP-1 are used to connect to T-CB-0 and T-CB-1 in each T640 router.

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-0 connect to the Routing Engine in slot RE0, and the ports on TX-CIP-1 connect to the Routing Engine in slot RE1.

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.
