40 x900 Series Switch
C613-03092-00 REV D
The following is example output from the show cflash test command when a
test is running.
Error messages are displayed when a file write fails. Failure could be because
of the card being removed or an error in the card itself. For more information
about these test commands and others for CFlash, see the Managing the File
System chapter in the Software Reference.
Secure Digital (SD) Card
Secure Digital cards are a memory expansion option for AT-9924Ts and
x900-24X switches. They use flash memory to provide non-volatile storage, and
are smaller than CompactFlash cards. They are removable and therefore
portable, and each card has a large storage capacity.
Data such as releases, GUIs, and configurations can be stored on SD cards, and
files can be manipulated with the command line interface (CLI). However, you
cannot run release, GUI, or package files directly from the card; they must be
loaded into NVS or onboard flash.
Important Anyone with a compliant reader can read SD cards so do not keep
sensitive data on them.
Approved SD card The Secure Digital card tested and approved for x900-24X switches is
AT-SM512A-002 512 MBytes (RoHS compliant). Storage capacity varies
because of formatting and additional functions that use available space. Cards
with a different capacity or from other vendors may also work with the switch.
Inserting and
removing an SD card
You can insert a card into the SD slot at any time. Just push the card into the
slot until you feel it latch.
When data is being written to or read from the card, the SD LED on the front
panel of the switch flashes green. Do not remove the card when it is active or
you will corrupt the data being read or written, and may corrupt other data on
the card. Wait until the LED remains off before releasing the card. To remove
the card, use a press-and-release action. Avoid touching the metal contacts.
To safeguard the data, store the card immediately in its case or somewhere
away from heat, humidity, or dust. Do not store it near electrostatic,
electromagnetic, magnetic or radioactive fields. If necessary, clean with a soft
dry cloth.
