Reading LED Indicators
This appendix provides a summary of all the LEDs (status indicators) used in the router system. The
LEDs on the chassis front panel and on the RP indicate the system power and route processor status;
LEDs on the rest of the interface processors indicate the status of the individual interface processor
and its interfaces.

Front Panel LEDs

Three system status LEDs on the front of the router, shown in Figure B-1, indicate the status of the
system and the power supplies. The normal LED goes on to indicate that the system is in a normal
operating state. The upper power and lower power LEDs light to indicate that a power supply is
installed in the indicated power supply bay and is providing power to the system. The power LEDs
go out if the power supply in the corresponding bay reaches an out-of-tolerance temperature or
voltage condition (for descriptions of thresholds and status levels, refer to the section "Environmental
Monitoring and Reporting Functions" in the chapter "Product Overview"). The front panel normal
LED is controlled by the RP, which contains an identical normal LED that provides system status on
the rear of the chassis.
Figure B-1 Router Front Panel LEDs
On the router front panel, the upper and lower power LEDs light when the power supply in the
corresponding bay is installed and supplying power to the system. Both LEDs should light in systems
with redundant power. The front panel LEDs are described in the following section.
