Function

Description

Input protection

Input overvoltage protection

In this protection state, the power module is turned off and stops supplying power. When the system recovers from input overvoltage, the power module can automatically start supplying power again.

Input undervoltage protection

In this protection state, the power module is turned off and stops supplying power. When the system recovers from input undervoltage, the power module can automatically start supplying power again.

Input overcurrent protection

In this protection state, the power module is turned off and stops supplying power. The power module cannot automatically start supplying power again and needs to be replaced.

Output protection

Output overvoltage protection

In this protection state:

  • If output overvoltage is caused by the power module itself, the power module stops supplying power. When the system recovers from output overvoltage, the power module cannot automatically start supplying power again.
  • If output overvoltage is caused by increase of the input voltage received from the external power source, the power module stops supplying power. When the system recovers from output overvoltage, the power module can automatically start supplying power again.

Output overcurrent protection

In this protection state, the output current is limited to a certain value. When the system recovers from output overcurrent, the power module can automatically start supplying power again.

Output short-circuit protection

In this protection state, the power module supplies power intermittently, and the output current is limited to within a range. When the system recovers from output short-circuit, the power module can automatically start supplying power again.

Overtemperature protection

When the temperature of the power module exceeds a specified threshold, the power module stops supplying power. When the temperature falls into the normal range, the power module automatically resumes power supply.

Hot swapping

The power module is hot swappable.

1. Power switch
NOTE:
  • When the power switch is turned ON, the power module supplies power to the chassis.
  • When the power switch is turned OFF, the power module does not supply power to the chassis.
2. Ejector lever
NOTE:

Raise the ejector lever to release the power module from the slot, and lower the ejector lever to lock the power module in the slot.

Indicator

Color

Description

INPUT

Green

Steady on: The input power of the power module is in the normal range.

Blinking: The power module is in an input undervoltage or input overvoltage condition.

Off: The power module receives no input power.

OUTPUT

Green

Steady on: The output power of the power module is in the normal range.

Off: The power module provides no output power.

ALARM

Red

Steady on: The power voltage is experiencing overtemperature, external short circuit, output overvoltage, output overcurrent, or a fan failure.

Blinking: Communication between the power module and CMU has been interrupted.

Off: The power module is working normally.
