T640 T-Series Control Boards (T-CBs) Component Description
Each T-CB consists of the following components:
- 100-MB Ethernet switch for intermodule communication.
- PCI bus to the Routing Engines.
- Processor subsystem (SPMB).
- Three LEDs, located on the T-CB faceplate, indicate its status. Table 1 describes the functions of the T-CB LEDs.
- The T-CB online/offline button, located on the faceplate. This button is nonfunctional.
- Two configuration switches, located on the faceplate:
- For a standalone T640 router, the M/S and CHASSIS ID configuration switches must always be set to S and 0.
- For T640 routers connected to a TX Matrix platform, the M/S and CHASSIS ID configuration switches must always be set to M and the chassis identifier (ID) of the router. In this case, both T-CBs must have the same chassis ID. For more information, see the TX Matrix Router Hardware Guide.
- Two RJ-45 ports labeled AUX and CIP on
the T-CB faceplate.
- For a standalone T640 router, these ports are not used.
- For T640 routers connected to a TX Matrix platform, only the CIP port is used. For more information, see the TX Matrix Router Hardware Guide.
