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.
