1. Locate the firmware file you wish to boot from.
2. (Firmware below R9.4a only): Rename the file to fit the 8 dot 3 filename format (see “Card Type and
Format” on page 44 ).
Recommended naming scheme:
PPP-TMM.mmb
where:
Example of an original firmware filename:
snap-pac-r2-R9.0a.bin
Example of the same firmware file, renamed:
R2-R9.0a
3. Create a directory on the card in the root and name it:
boot
Remember, if you are looking at the card in the controller , you create the
boot
directory in the
sdcard0
directory. If you are looking at the card in a card reader , create the
boot
directory at the top
level. The controller’s file system treats the card as a directory named sdcard0.
4. Copy the renamed firmware file to the
sdcard0/boot
directory on the card.
Here’s how it might appear if you are looking at the card in the controller:
IMPORTANT:
The boot directory must contain only one firmware file. If it contains more than one, the wrong
firmware may be loaded.
5. If the card contains a command file or any other firmware files, delete them.
6. To boot the controller from firmware on the card, turn the controller off and insert the card in the
controller’s card slot. Turn the controller back on. (Or insert the card and then quickly push and release
the controller’s Reset button.)
If the boot directory exists on the card, the STAT LED blinks green three times, quickly. Firmware is loaded.
If the STAT LED blinks red, see “Blink Codes” in this chapter to determine the problem.
If the STAT LED blinks green two times, either the boot directory is not present, the firmware file is invalid
or does not match the controller, or the controller is an SSD controller.
When the STAT LED no longer blinks steadily, but blinks only once every five seconds, you can remove the
card. When the card is removed, the controller continues running the firmware on the card until power is
cycled or the controller is reset. If you need to know whether the controller booted from the card or from
