A.1 Smart Card
The configuration is stored in a card in the device and is read each time the device boots. This configuration is gen-
erally stored in the Flash memory of the device. However, in some models, you can use an external device in order
to store the configuration: a
Smart Card
, which simplifies the transfer of configurations from one device to another.
The information is compressed in order to take advantage of the space available in the
Smart Card
. The choice of
the active storing medium where you read the configuration and where this is stored is carried out through console
commands. These commands can be found in more detail in the “Dm704-I Configuration and Monitoring” manual.
A.1.1 Description and insertion
The
Smart Card
is a card with an integrated circuit permitting you to store and process information. The available
space is variable, however it can always be measured in Kilobytes. The external aspect of the card is displayed in
the following figure: on one side of the card you can see the integrated circuit and on the other there is an arrow in-
dicating which way to insert the card.
Fig. 14:
Aspect of a SmartCard
In those models that have this device, the
Smart Card
is inserted in the slot located on the front panel of the equip-
ment. The card should be placed in the slot so that the arrow is face up and the chip face down. The card must be
carefully inserted following the arrow until a small click is heard.

SmartCard insertion slot
Next to the insertion slot you can see a LED which indicates the card activity. This LED lights up in green when it is
reading or writing in the card and remains off when there is no activity.
Note
DO NOT extract or introduce the card when the activity LED is on. Otherwise, data stored in the card
may be lost.
A.1.2 Viewing the content
The content of the
Smart Card
may be viewed from either the console or through FTP.
• In order to view the content of the
Smart Card
, or the free space, use the ‘FILE LIST’ command from the configura-
tion menu (please see manual “Dm704-I Configuration and Monitoring”). Given that the
Smart Card
is a slow
device, it may take a few seconds to respond.
