Appendix B Reading Led Indicators; Dc Ok Led - Cisco 7000 Series Hardware Installation And Maintenance Manual

A P P E N D I X
This appendix provides a summary of all the LEDs (status indicators) used in the router. The LED
on the interface processor end of the router and on the RP indicate the system power and processor
status; LEDs on the rest of the interface processors indicate the status of the individual interface
processor and its interfaces.

DC OK LED

The DC OK LED, on the interface processor end of the AC-input and DC-input power supplies, goes
on when the power supply is receiving AC or DC source power and providing DC power to the
internal system components. The power supply monitors its own temperature and internal voltages.
For a description of the power supply shutdown conditions and threshold status levels, refer to the
section "Environmental Monitoring and Reporting Functions" in the chapter "Product Overview."
