CompactFlash Card
CompactFlash (CFlash) cards are a memory expansion option for the following
switches running the AlliedWare operating system:
■
AT-8948
■
x900-48FE
■
x900-48FS
■
AT-9924T
■

Data such as releases, patches, and configurations can be stored on these cards,
and files can be manipulated with the command line interface (CLI). However,
release and patch files cannot be run directly from the card, but must be loaded
into either NVS or on-board flash.
Important
Anyone with a compliant reader can read CFlash cards so do not
keep sensitive data on them.
Approved
CFlash card
The CompactFlash card approved for the x900-48FE, x900-48FS, and AT-9900
series switches is AT-CF128A-00 128 MBytes. Other cards are unlikely to work
with the switch.
Inserting and
removing a
CFlash card
You can insert the card into the CompactFlash slot at any time; it takes about
two seconds to initialise. The following CLI message confirms that the card has
been inserted:
Info (1106257): Compact flash card 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 CFlash card is not compatible with the
switch:
Info (3106300): Compact flash card initialisation
unsuccessful.
Important
When data is being written to or read from the card, the CF LED on
the front 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.
