LEDs
The LEDs described in the following sections indicate the basic
status of hardware components.
LEDs on the Craft Interface
The craft interface provides status and troubleshooting information at a glance.
It is located on the front of the chassis above the FPC card cage, as shown in
Figure 1. The LEDs on the craft interface include the following:
Alarm—The circular red alarm LED at the upper left of the craft interface
indicates a critical condition that can result in a system shutdown. The
triangular yellow alarm next to it indicates a less severe condition that requires
monitoring or maintenance. Both alarms can occur simultaneously. When
an alarm LED is lit, the LCD describes the cause of the alarm. For more
information about the alarm LEDs, see “Alarm LEDs and Alarm Cutoff/Lamp
Test Button” on page 28. For more information about the causes of alarms,
see “Chassis and Interface Alarm Messages” on page 209.
FPC—For each of the FPC slots in the router, there are two LEDs and an
offline button located on the craft interface directly above the slot. The green
LED labeled
OK
and the red LED labeled
FAIL
indicate FPC status. For more
information, see “FPC LEDs and Offline Button” on page 31.
Host module—Two sets of LEDs at the upper right corner of the craft interface
indicate the status of the two host modules. Each set includes three LEDs—a
green one labeled
MASTER
, another green one labeled
ONLINE
, and a red one
labeled
OFFLINE
. For more information, see “Host Module LEDs” on page 31.
