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.
Displaying data
about a CFlash card
To display information about a CompactFlash card, including card size, file
count, and serial number, insert the card and enter the command:
show cflash
To display cluster ranges on a card, insert the card and enter the command:
show cflash test
The following figure is an example of output from the show cflash test
command when no test is running.
Testing a CFlash card It is important to fully test the hardware interface of the switch to the CFlash
card. This test consists of reading vendor information and reading and writing
to every part of the card.
To test the card, insert it in the CF slot and enter the command:
enable cflash test start=startnumber end=endnumber
where startnumber and endnumber are positive integers within a cluster range.
The end number must be higher than the start number. Cluster ranges are
displayed in the output of the show cflash test command.
The test software reads the file allocation table and displays a list of free
sectors. Sectors can be tested as single sectors or as a range. The test consists of
a write/read/verify cycle.
To stop the test, use the disable cflash test command. To display test results
while a test is in process, enter the show cflash test command. Also, use this
command when testing is not active to display the blank clusters range on the
card.
