LEDs on each power supply faceplate (see Figure 24 on page 46) indicate the status of
the power supply. In addition, a power supply failure triggers the red alarm LED on the
craft interface. Table 17 on page 46 describes the functions of the power supply LEDs.

Fault Tolerance When One Input Fails or is Disconnected
If this input fails, the router shuts down.
NOTE: We recommend that you install redundant power
supplies.
If an input on one power supply fails, the other power supply
assumes the electrical load for all inputs. If one input on the other
power supply is not functional, the router shuts down.
State Description
On steadily Circuit breaker is on.
Off Circuit breaker is not turned on, or
host subsystem has detected a
failure and has turned the circuit
breaker off.
