CAUTION: Make sure you know what is on the card before updating firmware! Any IP
address, configuration, or strategy data that exists on the card will also be saved to flash
memory along with the firmware.
7. To update firmware, insert the card in the controller’s card slot. Carefully insert a
straightened paperclip or stiff wire into the small hole on the controller labeled R
ESET
.
Press and hold the Reset button just until the STAT LED turns solid green, and then
immediately release the button.
Firmware is updated and saved to flash memory. (If IP address, configuration, or
strategy files are on the card, they are also saved to flash memory.) When finished, a file
named
response
is placed in the root directory of the card; this file indicates the
success or failure of commands in the command file. Then the controller restarts.
8. Wait until the STAT LED blinks only once every five seconds, and then remove the card.
Booting from Firmware on the Card
You can also boot the controller from firmware on the card, rather than from the firmware in
flash memory, for example to test new firmware before updating it on the controller.
You can write to the card in one of two ways: either use your PC to FTP files to the card in
the controller, or use a card reader with your PC and simply copy files with Windows
Explorer.
NOTE: Controllers configured for Secure Strategy Distribution (SSD) cannot boot from the card.
1.
Locate the firmware file you wish to boot from and rename it to fit the 8 dot 3 filename
format (see
“Card Type and Format” on page 50 ).
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
2.
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.
3.
Copy the renamed firmware file to the
sdcard0/boot
directory on the microSD card.
Here’s how it might appear if you are looking at the card in the controller:

b = controller type (R1, R2)
