T1600 T Series Control Boards (T-CBs) Description

 

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

  • 100-MB Ethernet switch for intermodule communication.

  • PCI bus to the Routing Engines.

  • Switch processor mezzanine board (SPMB).

  • Three LEDs, labeled MASTER, FAIL, and OK, are located on the T-CB faceplate, and indicate its status.

  • The T-CB online/offline button, located on the faceplate. This button is nonfunctional.

  • Two configuration switches, located on the faceplate: the M/S and CHASSIS ID configuration switches must always be set to S and 0 for a standalone T1600 router.

  • Two RJ-45 ports labeled AUX and CIP on the T-CB faceplate, which are not used for the T1600 router.
