bridge
short-circuits.
Minor  The load is
excessive.
 Derating reduces
the rated system
power.
 The module is
damaged.
Critical  The bypass fan is
not functioning
properly, or the
air channel is
blocked.
 The ambient
temperature
exceeds the
upper threshold.
 The load is
excessive.

2. If the load is normal, replace
the power module.
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.
