controller needs to reset to
detect the new sled.
• The reset to default button
does not work
Operational Code Firmware
Behavior
• FCB firmware disables
network/SNMP service
• FCB firmware update is done

protocol
• The firmware update may fail
but not be broken if you
install a compute sled into
the server enclosure while the
FCB firmware update is in
progress
• The reset to default button
does not work
