T1600-SIB Description

Figure 1 shows a T1600-SIB. T1600-SIBs are supported only on standalone T1600 routers. A T1600 router in a routing matrix does not support T1600-SIBs.

Each T1600-SIB consists of the following components:

• Switch fabric ASICs.
• High-speed links to each FPC.
• SIB online/offline button, located on the SIB faceplate.
• Three LEDs—ACTIVE, OK, and FAIL—located on the SIB faceplate that display the status of the T1600-SIB. The OK and FAIL LEDs are replicated on the craft interface.
