Updating the Firmware and Configuration
The firmware and configuration are saved in flash memory in the ServerNet II Switch.
Upon power on or a hard reset, the ServerNet II Switch starts running the firmware and
configuration.
Firmware and Configuration File Names
Table 4-31 lists the firmware and configuration files provided on the SUT. These same
files are available in the T0569AAB and T0569AAE SPRs.
Firmware and Configuration Compatibility With the NonStop
Kernel
Before updating the firmware and configuration of an installed cluster switch, you must
ensure that ServerNet nodes connected to the cluster switch are running a version of
the NonStop Kernel that is compatible with the new firmware and configuration.
Table 4-31. Firmware and Configuration File Names
Description File Notes
ServerNet II Switch
firmware file
$SYSTEM.SYSnn.M6770 None.
ServerNet II Switch
configuration library file
$SYSTEM.SYSnn.M6770CL “CL” stands for Configuration
Library. Depending on the
configuration file version, this
file supports up to three
configurations (X1/Y1, X2/Y2,
and X3/Y3).
ServerNet II Switch
configuration reserved
file
$SYSTEM.SYSnn.M6770CR “CR” stands for Configuration
Reserved. This file is empty
and is reserved for future use.
Caution. All nodes attached to a cluster switch whose firmware and configuration will be
updated with T0569AAB or T0569AAE must be running a version of the operating system that
is compatible with the T0569 SPR to be downloaded. Any nodes that do not meet these
requirements might experience permanent loss of Expand traffic across the cluster switch
when the new firmware and configuration are loaded on the cluster switch. Ta bl e 4- 32
on
page 4-99 describes the NonStop Kernel requirements for ServerNet nodes connected to
cluster switches that will be updated.
