The craft interface includes the following LEDs:
•
Alarm LEDs—One large red circular LED and one large yellow triangular LED, located on the upper right
of the craft interface, indicate two levels of alarm conditions. The circular red LED lights to indicate a
critical condition that can result in a system shutdown. The triangular yellow LED lights to indicate a less
severe condition that requires monitoring or maintenance. Both LEDs can be lit simultaneously. A
condition that causes an alarm LED to light also activates the corresponding alarm relay contact on the
craft interface.
•
Host subsystem LEDs—The host subsystem consists of a Control Board with a Routing Engine (CB-RE).
Three LEDs, MASTER, ONLINE, and OFFLINE, indicate the status of the Routing Engine function of the
host subsystem. A green MASTER LED indicates that the host is functioning as the master. The ONLINE
LED indicates that the host is online. The OFFLINE LED indicates that the host is installed but the Routing
Engine is offline. The Routing Engine component of the host subsystem LEDs is located on the upper
right of the craft interface and labeled RE0 and RE1.
•
Power supply module LEDs—A set of nine bicolor LEDs, labeled (PSM), indicates the status of each PSM.
Green indicates that the PSM is functioning normally. Red indicates that the PSM is not functioning
normally. The PSM LEDs are located at the top of the craft interface, and are labeled 0 through 8.
•
Line-card LEDs—Ten bicolor LEDs, LC0 through LC9, for the ten line cards (MPCs), indicate the status.
Green indicates the line card is online, green blinking indicates that the line card is booting, and red
indicates a failure. The line-card LEDs are located along the bottom of the craft interface.
•
SFB LEDs—Eight bicolor LEDs, SFB0 through SFB7, indicate the status of each SFB. Green indicates the
SFB is online, green blinking indicates the SFB is booting, and red indicates a failure. The SFB LEDs are
located along the middle of the craft interface along the bottom.
•
CB-RE—Two bicolor LEDs, CB-RE0 and CB-RE1, indicate the status of each CB-RE. Green indicates the
CB-RE is online, green blinking indicates the CB-RE is booting, and red indicates a failure. The CB-RE
LEDs are located along the bottom far left and far right of the craft interface.
•
Fan tray LEDs—Four bicolor LEDs, 0 through 3, indicate the status of the upper two and lower two fan
trays. Green indicates the fan trays are functioning normally, and red indicates that a fan tray has failed.
The fan tray LEDs are located on the upper middle of the craft interface.
Component LEDs
The following LEDs are located on various router components and display the status of those components:
•
MPC LED—One LED labeled OK/FAIL on each MPC faceplate indicates the MPC's status. For more
information, see the MX Series Interface Module Reference .
•
MIC LED—One LED labeled OK/FAIL on each MIC faceplate indicates the MIC's status. For more
information, see the MX Series Interface Module Reference .
•
SFB LEDs—One LED, labeled OK/FAIL, on each SFB faceplate indicate the status of the SFB. If no LEDs
are lit, the master CB-RE might still be booting or the SFB is not receiving power.
