Updating the Boot Code
If you have determined that your modems are compatible with 2.00 or later boot
code, then you may update them. WARNING: Boot code version 2.02 requires
that you have a controller running firmware version 2.40 or later. The following
instructions assume that your controller meets this requirement. To update the
controller, download the latest firmware from the CommPlete Resources web
page (see Q61), and follow the instructions that accompany the firmware.
1. Using an FTP client program, such as WS_FTP, delete from the controller all
of the files in the directory "B:\MMM\MR.LOG\". These files are event files
that the controller generates hourly, and they usually take up all the space on
the B drive.
2. Transfer the boot code file to the root directory of the controller's B drive.
CAUTION: Do NOT transfer the boot code file to the controller's A drive.
The A drive does not have enough space for the file. Transferring the file to
the A drive will cause errors in the file and, perhaps, errors in the system.
3. Close your FTP session. Then open a Telnet session with the controller.
(Note: A terminal attached to the controller with a null-modem serial cable
will perform the same function that the Telnet session will perform.)
4. Log in as the supervisor. The default username and password are both
supervisor.
5. At the # prompt, type B: to change to the B drive.
6. Type DIR or LS to display the contents of the root directory. Compare the
size of the original boot code file to the size of the copied file on the
controller. If the sizes do not match, then delete the copy from the controller
and re-transfer the original file to the controller. The copy MUST be the same
size as the original for the update to work properly.
7. If the controller's copy of the boot code file is the correct size, type UPDATE
-BOOT BT_202.HEX modems, where "modems" is the specifier(s) of the
modems you wish to update. (For example, 2A:2H identifies the first eight
modems on the modem card in slot #2.) The controller will display the
conditions of the update—-the number of devices and the name of boot code
file—-and it will ask you if they are correct.
8. Press ENTER to confirm the conditions, or type n to abort the update process.
If you confirm the conditions, the controller will check the file for errors. DO
NOT PRESS ANY KEYS DURING THE FILE CHECK. Doing so will abort
the file check and start the update of the boot code, which risks flashing
damaged code into the modems.
9. If the controller finds no errors in the file, it will start updating the modems.
The # prompt will reappear, and the modems will reset. During the update,
the CD LED on each of the modems will flash each time its modem receives
a packet of boot code from the controller.
