Backing Up a Customer Database
Keeping three backups allows you to go further back in time to find an 
error-free database.
SX-200 EL/ML
Backing up the database copies the database from memory to a file on 
the attached maintenance PC. Back up a database after you make 
changes to it. To back up the customer database, use 
the Maintenance screen in the Terminal or Hyperterminal 
Communication’s Package and proceed with the following steps:
1. Select the following commands: 
SYSTEM
DATABASE
BACKUP
ENTER
The system prompts you for the file name.
2. Enter the file name.
ENTER
CONFIRM
The system then prompts you to exit to a local Kermit session. 
Ensure that the Kermit session is set to binary mode because the 
customer database information must be saved as a binary file.
3. In the Kermit session, issue the RECEIVE command. 
While the backup is in progress, the top seven-segment LED on the 
MCC shows “A”, and the lower seven-segment LED shows a dash 
that is circling in a clockwise direction.
After the file transfer has completed, the maintenance screen 
returns.
The message Download/Upload Successful  appears on the 
screen.Think of a meaningful filename. It can include abbreviations 
for the name of a remote site, the purpose or function of the 
database, or the version of the software.

SX-200 EL/ML Remote Software Download
Requirements:

A 4 MB Flash card. Make sure the toggle switch on the edge 
opposite the connector edge of the Flash card has the Write Protect 
disabled.

System option 109 (Remote Software Download) must be enabled. 
This is a purchasable system option.

The latest software downloaded onto your PC provided by MITEL 
On-Line or MITEL Product Support.
To Speed Up the Remote Software Download
To speed up the remote software download, increase the packet length 
to 900 and the block check type to 3 bytes CRC, using the Kermit 
protocol on your maintenance terminal.
To change the packet length
1. Select SYSTEM from the Maintenance screen.
2. Select the following softkeys:
DATABASE
SET_PARAM
RECEIVE
PACKET_SIZE
ENTER
The following message will display:
Enter Packet Length (10-1024)
3. Enter the Packet length (900) and select CONFIRM.
The screen confirms your setting with a display of the Kermit 
Receive Parameters and the Kermit Send Parameters.The remote software download time can take up to 3 
hours. We recommend that you do this operation during 
a slow time since the traffic on the switch affects the 
download time. To shorten the remote software 
download time to approximately 30 minutes, increase the 
size of the packet length to 900 and change the block 
check type to 3 bytes CRC.

Downloading the Remote Software
Downloading LIGHTWARE 19 software for the BCC III and the MCC 
with a 4 Meg Flash card requires a two step procedure. You download 
the software for the MCC first and then download the software for the 
BCC III. Because the system only accepts software that is compatible, 
the system will inform you of the status of the software during the 
download process.
1. Back up the database.
2. Load the new operating software from the PC.
Select the following commands from SYSTEM maintenance:
DATABASE
SW_RESTORE
ENTER
3. Select CONFIRM if you agree with the terms stated in the window.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.
