Run the systemVerification command to verify that the switch does not have hardware problems. To
run this command root access is required. Refer to the Fabric OS Command Reference for more
information on this command.
On the Brocade 24000 and 48000, replace the specified FRU.
For the Brocade 3900, replace the motherboard FRU.
For the Brocade 200E, 3016, 3250, 3850, 4012, 4016, 4018, 4020, 4024, 4100, 4900, 5000,

Severity CRITICAL

Message
<timestamp>, [EM-1004], <sequence-number>, FFDC, CRITICAL, <system-name>,
ID>
Probable Cause Indicates that a field-replaceable unit (FRU) failed to power on and is not being used. The type of
FRU is specified in the message.
The FRU ID value is composed of a FRU type string and an optional number to identify the unit, slot,
or port.
The Brocade 3250 has one power supply and three fans, and the Brocade 3850 has two power
supplies and four fans. Values for the individual fans and power supplies for these switches might
display, but these parts cannot be replaced: the entire switch is a FRU.
The Brocade 3016 does not have any fans, power supplies or world wide name (WWN) cards.
The Brocade 200E, 4012, 4016, 4018, 4020, and 4024 have 4 fans and 1 power supply, but these
parts cannot be replaced: the entire switch is a FRU.
Recommended Try reseating the FRU. If the message persists, replace the FRU.

Probable Cause Indicates that a blade in the specified slot or the switch (for nonbladed switches) is being shut
down for environmental reasons; its temperature or voltage is out of range.
Recommended Check the environment and make sure the room temperature is within the operational range of the
Action switch. Use the fanShow command to verify fans are operating properly. Make sure there are no
blockages of the airflow around the chassis. If the temperature problem is isolated to the blade
itself, replace the blade.
Voltage problems on a blade are likely a hardware problem on the blade itself; replace the blade.
