SD Flash Memory Card
The Cisco IR8340 router supports a flash memory card that makes it possible to replace a failed router without
reconfiguring the new router. The slot for the flash memory card is on the front of the router. The flash card
is hot swappable and can be accessed on the front panel in non hazardous locations only. A cover protects the
flash card and holds the card firmly in place. The cover is hinged and closed with a captive screw. This prevents
the card from coming loose and protects against shock and vibration.
For more information on inserting and removing the flash memory card, see
Card, on page
