Frequently Asked Questions (FAQs)

Q14. How do I update the firmware code of the modems in my

CommPlete Server?

A14. The instructions in this file use the scenario of updating the MT5634HD8

modems in slots 2-4. The steps below use this scenario to provide you with

examples of the commands to enter. The instructions also assume that you are

using a controller running 2.40 firmware or later.

1. Using an FTP client program, such as the one that comes with 95/98, delete

from the controller at least half of the files in directory "B:\MMM\MR.LOG\".

These files are event files that controller generates hourly, and they usually

take up all the space the B drive

2. Transfer the firmware file to the root directory of the controller's drive.

CAUTION: Do NOT transfer the firmware file to the controller's A The A

drive does not have enough space for the Transferring the file to the A drive

will cause errors in 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 perform.)

4. Log in as the supervisor. The default username and password are

"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 firmware 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 firmware file is the correct size, type UPDATE

HD8_104C.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 the firmware 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 firmware, 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.

10. To find out how much of the update that the controller has performed, type

UPDATE. The controller will respond with "No Update in Progress" when the

update is complete. In addition, the controller will reset the modems after

flashing them, causing the modems' LEDs to flash brightly for about twenty-

five seconds.
