Replacing a CF card
CAUTION:
Do not remove the CF card when the router is booting or the CF card LED is flashing. Otherwise, the
file system on the hardware or the CF card might be damaged.
The CF card is installed on the MPU of the router.
To replace a CF card:
1. Verify the CF card LED status.

If the LED is on, you cannot remove the CF card. You must use the umount cfa0:
command at the CLI to unmount the CF card and wait until the CF card LED is off. After you
execute the
umount cf command, if you want to continue to use the CF card, execute the
mount cf
command in user view to mount the CF card again.
For more information about the
umount
and
mount
commands, see file system
management in H3C SR8800-F Routers Fundamentals Command Reference .

If the LED is flashing, it means that data is being read from or written to the CF card. In this
case, you cannot remove the CF card. Wait until the CF card LED stops flashing.

If the LED is off, it means that the CF card is unmounted, and you can remove the CF card.
