| |
operation
of the power supply. This signal shall be a TTL compatible high
|
| |
level
for normal operation; low level for fault conditions. |
| |
Power-good
shall go to low level at least 1 ms before the +5V output |
| |
voltage
falls below the regulation limits described in 3.1 DC output |
| |

be minimum line voltage and maximum load. |
| |
All waveform
transitions shall be smooth and monotony, i.e. no oscillations. |
| |
The power-good

System Fault Signal |
| |
The Hot-Swap
Redundant Power Supply shall give fault signal (an open |

that will indicate the status of the power supply operation. |
| |
If one
of the power supply unit shut down, the power fault signal could
be |

generated.
This signal shall be high level for normal operation; Low level |
| |
for fault
conditions. |
| |
|

Alarm
Beeping Sound |
| |
The alarm
system monitors the power supply failure and provides alarm to |
| |
indicate
the status of the power supply. By checking the LED on the |
| |
power
supply, end users will be able to locate the defective power unit.The |
| |
alarm
system will give a beeping sound to indicate the power supply |
| |
failure
until that particular power unit is replaced. |
| |
Beeping
sound could be suspended before the failure power supply unit |
| |
replaced. |
