Craft Interface LEDs
The craft interface displays system status messages and allows you to troubleshoot the PTX5000. See
"PTX5000 Craft Interface LEDs" on page 23 .
NOTE: The FPC LEDs are located on the FPC faceplate.
LEDs on the craft interface include:
• Red and yellow alarm LEDs—One large red circular LED and one large yellow triangular LED indicate
two levels of alarm conditions. You can determine the cause of the alarm condition by looking at the
LCD on the craft interface.
• SIB LEDs—One bicolor green and red OK indicates the status of each SIB. One green (ACT) LED
indicates if the SIB is active and passing traffic. The SIB LEDs are located on the left of the craft
interface, and are labeled SIB0 through SIB8.
• 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.
