Replacing a CF card
CAUTION:
To prevent the file system on the hardware or the CF card from being damaged, do not remove the CF
card when the switch is booting or the CF card LED is flashing.
Before replacing a CF card, execute the umount command to unmount the CF card to ensure that the file
system on the CF card is not damaged when you remove the CF card.
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 load the CF card again.
After you replace the CF card, the system automatically loads the CF card.
To replace a CF card:
1. Log in to the switch to execute the umount command. For how to log in to the switch, see
"Connecting your switch to the network."
2. Use a hard object to press the eject button of the CF card reader as shown by callout 1 in Figure
57 . The reader ejects the card part way out of the slot.
3. Remove the CF card from the reader and put it in an antistatic shielding bag.
4. Install a new CF card. For the installation procedures, see "Installing FRUs."

Replacing a transceiver module
WARNING!
When you install or remove a transceiver module:
• Do not stare at the fibers to avoid hurting your eyes.
• Do not touch the golden plating on the module.
Make sure the optical transceiver modules at the two ends of an optical fiber are the same model.
