CompactFlash Card
AT-9800 Series switches have a CompactFlash slot on their rear panel.
CompactFlash cards increase the flash memory available for file storage.
CompactFlash files can be manipulated using the command line interface. Any
type of data, including releases, patches, GUIs and configurations can be stored
on CompactFlash cards. However, release, patch, and GUI files cannot be run
directly from CompactFlash. These files must be loaded into either NVS or
on-board flash. CompactFlash functionality is supported by Software Version
2.5.1 and later.
Important
Anyone with a compliant reader can read CompactFlash cards so
do not keep sensitive data on them.
The following CompactFlash cards have been approved for use with AT-9800
Series switches:
■
AT-CF032A-00 32MB CompactFlash card
■
AT-CF128A-00 128MB CompactFlash card

Installing and removing a CompactFlash card
CompactFlash cards can be inserted into the CompactFlash slot at any time. It
takes approximately two seconds for an inserted card to be initialised. The
following CLI message confirms that the card has been inserted:

The following message confirms that the card is ready to use:
Info (1106268): Compact flash card initialisation successful.
The following message means that the CompactFlash card is not compatible
with the switch:

Important
When data is being written to or read from the card, the
CompactFlash Activity LED on the rear panel of the switch is green. Do
not
remove the card when it is active or you will corrupt the data. Wait until the LED
is off before ejecting the card.
