Server enclosure
with storage sleds
only
•FCB firmware enables
network/SNMP service
• FCB firmware update is done
by TFTP via SNMP set object
property
•FCB firmware detects sled
modules during initialization
only. When you replace a
storage sled with a compute
sled, the FCB controller
needs to reset to detect the
compute sled.
• The reset to default button
works
•FCB firmware enables
network/SNMP service
• FCB firmware update is done
by TFTP via SNMP set
object property
• Use the SNMP SET/GET
commands to request for a
specific variable
• FCB firmware send traps to
remote client when critical
errors occur.
• You can download or upload
the FCB configuration
information by TFTP via
SNMP set object property
• 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
