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.
