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 Routing
Engine (CB-RE). Three LEDs,
the Routing Engine function of the host subsystem. A green

offline. The Routing Engine component of the host subsystem LEDs located on the
upper right of the craft interface and labeled
Power supply module LEDs—A set of eighteen bicolor LEDs, labeled (
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 in the
top of the craft interface, and are labeled
through 17 for the top PSMs.
Line card LEDs—Twenty bicolor LEDs,
(MPCs), and through
LC10
indicates the line card is online, green blinking indicates that the line card is booting,
and the red indicates that a failure. The line card LEDs located along the bottom of
the craft interface.
SFB LEDs—Eight bicolor LEDs,
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,
Green indicates the SFB is online, green blinking indicates the SFB 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,
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.
The following LEDs are located on various router components and display the status of
those components:
