Configuration guidelines for use of software images with the 128MB 7210
SAS-D platform
The new 7210 SAS-D platforms with 128MB flash can boot entirely new software releases. The
older images cannot be used with the new devices. The older 7210 SAS-D platforms with 64MB
flash can use any image. All new devices are shipped with the latest bootrom. The system
bootrom, bootloader and Timos image introduces the following checks to prevent use of older
releases with the new hardware:
• If a user issues an admin reboot upgrade with an older boot.tim, then bootrom detects and
fails to load the bootloader, instead the bootrom uses the golden bootloader, loads it for
booting with the bootrom and finally loads both.tim.
• If a user issues an admin reboot upgrade with an older boot.tim, and an older both.tim,
then bootrom detects and fails to load the bootloader, instead the bootrom uses the golden
bootloader and stops booting as the user specifies an older version of the both.tim, which
the system cannot use. This process results in loss of management connectivity.
• If a user issues an admin reboot upgrade with an older boot.tim, an older both.tim as
primary, and a newer both.tim as secondary, then the bootrom detects and fails to load the
bootloader, instead the bootrom use the golden bootloader. The bootloader checks the
primary location for a compatible both.tim image and as the image is an older version the
boot fails. The bootloader then checks the secondary location for a compatible both.tim
image and as the image is a newer version image the bootloader successfully boots the
system.
•The admin>update-golden-bootstrap CLI command does not update the golden-
bootstrap image with the boot.tim specified in the parameter value, if the boot.tim is not a
new image.
Out-of-band (OOB) Ethernet Management Port
Note: Out-of-band Ethernet port is not supported on 7210 SAS-D and 7210 SAS-K devices.
The 7210 platforms support out-of-band ethernet management port for management of the node.
An Out-of-band Ethernet port can be used to download the TIMOS image file and the
configuration file by creating a BOF file manually. The out-of-band management port allows for
use of both IPv4 and IPv6. The Configuration guidelines section below provides information on
the platforms that can support IPv6 for out-of-band management port.
Please check the release notes to know the software release where support for out-of-band
management port is available and for software release availability of IPv6 support.
