III. It is recommended that you back up your database before you

perform a system upgrade.

1. Back up the database.

2. Launch the Hyperterminal application and set up a connection at 19.2

bps.

3. Logon to the maintenance terminal and load the new operating

software from the PC.

Select the following commands from SYSTEM maintenance:

DATABASE

SW_RESTORE

CONFIRM.

4. When the message “Return to your local KERMIT session now”

appears, return to your KERMIT session.

5. Use KERMIT to transfer and send the remote.fix file.

If the system only has a BCC II and the remote.fix file has completed,

the maintenance screen shows the message “Download/Upload

Successful”.

If the system has a BCC III, continue with the next steps.

6. If necessary, use KERMIT to transfer and send the bccIII.fix file. To

see the status of the flash card, select the following commands:

SYSTEM

SHOW

IDENTITY.

7. After all the file transfers are complete and at a time of low or no

traffic, return to the Maintenance application. Select SYSTEM,

RESTART, RESET SYSTEM, and then CONFIRM to reset the

system to activate the new software.

Note that upgrading software for the BCC III with a 4 Meg Flash

card always requires you to download the software for the main

control card first.
