T1600 LED Overview

Craft Interface LED Overview

The craft interface displays system status messages and allows you to troubleshoot the T1600 router. The craft interface is located on the upper front of the router. It contains LEDs, buttons, and an LCD display showing status messages for the router.

LEDs on the craft interface include the following:

• Alarm LEDs—One large red circular LED and one large yellow triangular LED, located on the upper left of the craft interface, indicate two levels of alarm conditions. You can determine the cause of the alarm condition by looking at the LCD on the craft interface.

  See T1600 Craft Interface Alarm LEDs and ACO/LT Button.

• Host subsystem LEDs—Three LEDs (one green MASTER, one green OK, and one red FAIL) indicate the status of each host subsystem. The host subsystem LEDs are located on the upper right of the craft interface, and are labeled HOST0 and HOST1.

  See T1600 Craft Interface Host Subsystem LEDs.

• SIB LEDs—Two LEDs (one red FAIL and one green OK) indicate the status of each SIB. The SIB LEDs are located on the upper right of the craft interface, and are labeled SIB0 through SIB4.

  See T1600 Craft Interface SIB LEDs.

• FPC LEDs—Two LEDs (one red FAIL and one green OK) indicate the status of each FPC. The FPC LEDs are located along the bottom edge of the craft interface, and are labeled FPC0 through FPC7.

  See T1600 Craft Interface FPC LEDs.

Component LED Overview

• Connector interface panel (CIP) LEDs—Two small LEDs on the left edge of the ETHERNET port on the CIP indicate the connection in use.

  Note: When RE-C1800 are installed, the LEDs are always yellow for both a 10-Mbps connection and 100-Mbps connection.

  See T1600 Connector Interface Panel (CIP) LEDs.

• SIB LEDs—Three LEDs on each SIB faceplate—ACTIVE, OK, and FAIL—indicate the status of that SIB.

  See T1600-SIB LEDs and TXP-T1600 SIB LEDs.

• T-CB LEDs—Three LEDs on each T-CB faceplate—ACTIVE, OK, and FAIL— indicate the status of that T-CB. If no LEDs are lit, the T-CB is not receiving power.

  See T1600 T-CB LEDs.

• LCC-CB LEDs—Three LEDs on each LCC-CB faceplate—ACTIVE, OK, and FAIL— indicate the status of that LCC-CB. The ACT and LINK LEDs indicate the status of each port. The JCS LINK port and LED are not currently supported. If no LEDs are lit, the LCC-CB is not receiving power.

  See T1600 LCC-CB LEDs.

• SCG LEDs—Three LEDs on each SCG faceplate indicate the status of that SCG. If no LEDs are lit, the SCG is not receiving power.

  See T1600 SCG LEDs.

• PIC LEDs—Each port on each PIC has an LED that indicates the status of the port.

  See the T1600 Core Router PIC Guide .

• Power supply LEDs—LEDs on each power supply faceplate indicate the status of that power supply.

  See T1600 Three-Input 240-A DC Power Supply LEDs , T1600 Four-Input 240-A DC Power Supply LEDs , or T1600 Three-Phase Delta and Wye AC Power Supply LEDs .
