Chapter 8 Upgrade of XSCF Firmware and Maintenance 8-7
8.1.7 Firmware Update Types and Timing
The firmware update includes two types: operator's update and automatic update
(automatic matching of versions).
TABLE 8-1 describes the firmware update types and
update times.
TABLE 8-1 Firmware Update Types and Timing
Type Description Conditions Update Time
Operator's update
(XCP update) Imports XCP and updates
the XSCF firmware and
OpenBoot PROM firmware
on the XSBs belonging to all
domains (including pooled
domains).
This is also referred to as
"XCP update." The system power is off
(input power is on and all
domains are stopped), or
power to the domains is on.
Note: The update is
completed at the time of a
reboot for application in all
domains. XCP update time
Automatic update
(Automatic matching
of versions) • When a CMU (Note 1) is
added or replaced, or the
XSCF Unit is replaced,
the firmware version of
each replacement
component is
automatically matched to
the version of the
replaced component.
(Note 2)
However, when a
component is replaced in
the state of input power off
(The cold replacement), the
firmware is not updated
automatically.
• When the DR function is
used to add, move, or
replace a system board
(XSB), the firmware
version is automatically
matched to the firmware
version in the domain
that uses the system
board.
The system power is off
(input power is on and all
domains are stopped), or
power to the domains is on.
• In the system with
redundant XSCF Units, If
you replace an XSCF
Unit by using the
maintenance guidance,
the firmware version of
the replacement XSCF
Unit is matched to the
firmware version of the
replaced XSCF Unit.
• In CMU addition or
replacement, the target
domain need not be
rebooted for application
of the OpenBoot PROM
firmware. However,
when the domain is
powered off, the number
of versions is matched by
the startup of the
domain.
• Time of CMU addition or
replacement. Or time of
replacement of an XSCF
Unit that is configured
redundantly
• Time of addition, move,
or replacement of a
system board by the DR
function
