Four LEDs on each two-input 160-A DC power supply faceplate indicate the status of
the power supply. In addition, a power supply failure triggers the red alarm LED on the
craft interface. Table 14 on page 43 describes the functions of the power supply LEDs.

Fault Tolerance When One Input Fails or Is Disconnected
If either input fails, the router shuts down.
NOTE: We recommend that you install redundant power supplies.
If either input on one power supply fails, the other power supply
assumes the electrical load for both inputs. If one of the inputs on
the other power supply is not functional, the router shuts down.
