Solution
1. Check that there is no overload.
2. Check that the module power is
not derated due to a fan fault.
3. If the alarm persists, replace the
power module.
1. Check the bypass fan and air
channel. If the fan is faulty,
replace it.
2. Check that the ambient
temperature has not exceeded
40° C.
3. Check that there is no overload.
1. Check the inter-rack parallel
system CAN bus.
2. Rectify the disconnection or short-
circuit fault.
3. Replace the ECM.
Replace the inter-rack parallel cable.
