158 Using the System Setup Program

By default, the FCB controller uses DHCP to acquire an IP address. The

system MUST follow the same DHCP retry mechanism that exists in the

BMCs (any parameter needed for this MUST be stored in the configuration

file). DHCP client MUST retry forever.

FCB Firmware Behavior

The following table lists the FCB firmware behavior.

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
works
