File List

When new software is sent to you or downloaded from our web site, it will usually consist of a zip file containing any or all of the following files:

PnnnnBMO.dwn - main executable version n.nnn, rename it to 'image' before uploading to your router.

image4.cx - 'Fall-Back' image that will be loaded if main image is corrupted, this provides basic functionality only. If any other 'imageN.cx' files exists on the router they should be deleted before loading this file. x = number of contiguous sectors required for the image in flash

*.rom - Bootloader version n.nn

PnnnnBMO.web - web image, this holds all the web pages

PnnnnBMO.wb2 - alternate web GUI (not always present)

logcodes.txt - Event priorities and textual expansion of the event codes

config.fac - if provided this is the basic factory configuration, holding the user button in for 5 seconds will overwrite the power-up config with this file and reboot.

General Update Procedure

Step 1: Download the zip file for your product and extract all the files into a single folder on your PC.

Step 2: Connect to the router to be upgraded using an FTP or SFTP client. Check for the presence of a "Fall-Back" image with a name other than the file supplied in the zip (e.g. image4.c2) This would be any file of the form imageX.cY. If such a file exists then use the FTP or SFTP client to delete it.

Step 3: Next check for any files with a .web or .wb2 extension. If present delete them using your FTP or SFTP client.

Step 4: On your PC rename the PnnnnBMO.dwn file to image.

Step 5: Using the SFTP or FTP client, upload all the files extracted from the PC to the outer.

Note: Be very careful not to lose power or reset the unit during the following step, or you may render the unit completely inoperable. Step 6: Connect to the router's command line interface (e.g. via telnet, SSH or one of the local serial ports) and type:

move <*.rom filename> sbios <enter>

e.g. "move s556v31M.rom sbios"

This overwrites the current sbios with the new sbios file. When complete after a few seconds the router should return 'OK'.

Step 7: Connect to the command line interface (e.g. via telnet or SSH or one of the local serial ports) and type:

scan <enter>

The scan command checks that the flash directory and all files are OK. If it returns any CRC errors leave the unit powered on and please repair the file. If you need help repairing the file contact technical support and do not power down or reboot the router.

Please check that the "image" file has an extra "data ok". Do not reboot unless the image file says "data ok"

Example:

scan
Please wait...
      direct ....ok
       sbios ....ok
      mirror ....ok
       image ....ok, data ok
   sregs.dat ....ok
      x3prof ....ok
  CAcert.cer ....ok
  cert01.pem ....ok
 privrsa.pem ....ok
  templog.c1 ....ok
  config.fac ....ok
   image4.c1 ....ok, data ok
LOGCODES.TXT ....ok
When all is completed and if the scan checks are OK type:

reboot <enter>

to reboot the unit, do NOT physically re-power it.

Step 8: When the unit has finished rebooting you may log on to the Web interface, browse to Administration --> Version Info and check that the "Software Build Ver" and "Bios Ver" versions have been updated. You can also check the current versions from the command line interface by typing ATI5<enter>.

If you encounter any difficulty during the process above, please contact Technical Support immediately. Do not remove power from the unit unless you are advised to do so by Support.
