Check that the rectifier is inserted in the subrack and secured properly. If the rectifier has
poor contact with the subrack, reset it and secure it to the subrack.
If the alarm persists, replace the rectifier.
Check whether the AC input voltage is greater than the rectifier AC overvoltage alarm
threshold or lower than the rectifier AC undervoltage alarm threshold.
If the rectifier input voltage is within a normal range but the alarm persists, replace the
rectifier.
Check whether the ambient temperature exceeds the upper threshold.
The battery voltage is below the lower threshold.
The battery temperature exceeds the upper threshold.
If the AC input power is unavailable, recover the AC power supply.
If the ambient temperature is higher than the upper threshold, decrease the temperature.
The battery voltage is below the lower threshold.
The ambient temperature exceeds the upper threshold.
If the AC input power is unavailable, recover the AC power supply.
If the ambient temperature is higher than the upper threshold, decrease the temperature.
