4 Boot Options
This chapter provides information about configuring boot option parameters.
4.1 System Initialization
When the 7210 SAS device is powered on, the system executes the boot.tim file
(also known as the boot loader or the bootstrap image) from the file system located
on one of the storage media available on the 7210 SAS platform. The boot.tim file
is the image that reads and executes the system initialization commands configured
in the Boot Option File (BOF).
If the boot.tim file is absent or invalid, and cannot be loaded, the platform-specific
handling is as follows:
• 7210 SAS-M
On this platform, the boot ROM loads the golden bootstrap image. The golden
bootstrap image is equivalent to a boot.tim file, but it is present outside the file
system, and can be updated and checked using special CLI commands.
• 7210 SAS-Mxp, 7210 SAS-R6, 7210 SAS-R12, 7210 SAS-T, 7210 SAS-S 1/
10GE, 7210 SAS-Sx 1/10GE, and 7210 SAS-Sx 10/100GE
Note: Some 7210 SAS platforms (including 7210 SAS-Mxp, 7210 SAS-R6, 7210 SAS-R12,
7210 SAS-T, 7210 SAS-S 1/10GE, 7210 SAS-Sx 1/10GE, and 7210 SAS-Sx 10/100GE)
do not ship with the bootstrap image. For these platforms, you must use one of the following
devices to access the boot.tim file to boot the system. Insert the device containing the
bootstrap image in the specified storage media location before powering on the system, as
follows:
• external flash
Insert the compact flash into the external compact flash slot.
• SD card
Insert the SD card into the SD card slot.
• USB device
Insert the USB storage device into the USB port.
Refer to the appropriate chassis installation guide for more information about the
prerequisites for the specific 7210 SAS platform. See Contents of Factory-shipped
7210 SAS Systems for a list of contents shipped with the system on each 7210 SAS
platform.
